Let me know...

If you encounter a bug in the program, please send details of the problem along with the Crash Report to bug@zofzpcb.com.
Set of gerber files (a subset even better) allowing me to repeat the problem is substantially helpful. The files will be kept secret.

ZofzPCB Log

Bug List / To Do / deferred:

  1. Space Navigator revision - features update.
  2. GerberX2 "%TF.FileFunction" for autoload.Gerber X2 logo
  3. Alberto's reported bugs in flattening - rewrite cross detection to n*log(n) scan line algorithm, as it is in effects/triangulation.
  4. There is unnatural transparency gradient, close to the board edges, when observed from some angles. Best fix would be "per pixel fog". I am slowly allowing myself to think about this more GPU power demanding method.
    gradient of bottom
  5. Sometimes board outline is routed via the drill file. This could be detected and possibly used instead of the board outline drawing Gerber file.
  6. I have build the menu (GUI) system on top of DXUT (3D graphics). I did it to enable working in a fullscreen mode. Fullscreen mode saves resources, especially for the older GPU - I still have fear that some users may suffer on GPU performance. It could be useful to have both systems: native windows GDI-GUI and current DXUT.
  7. Single layer board auto file to stackup assignment have top/bottom problems.

hot fix 4 of 4

  1. Some configurations of the edges, the "hollow" effect triangulation could cause a problem, visible as covering of holes. In a very specific cases, the algorithm could crash.
    shortcuted circle
  2. The "Net Selection Effect" menu is initially disabled, until a file load is executed.
  3. Truncated Reference Names in the IPC356 could not be matched to BOM file, causing the columns auto detection fail. The fix works only if the names do not overlap, after truncation.
  4. As it is taking so long to publish the new version - beta test release 1.0.18 (2019-11-07)

ver 1.0.5 (2019-03-08)

hot fix 3 of 4

  1. Binary mesh file (.zofzproj) format bug, related to complex apertures.
  2. Binary mesh file (.zofzproj) format is now LZWA compressed and AES encrypted.
  3. Binary mesh file (.zofzproj) format can be saved in a View-Only mode (premium feature). Component Modeler license is not required to view the components in this mode.
  4. When creating the View-Only file, it is possible to limit functionality, like UHD printouts, allowing viewing, but limiting reading of certain manufacturing details.
  5. More 3D components, THT: oscillator can, 4-pin push-button, 4-pin universal DIP, 2-row pin headers, including 90deg, barrel power connector; SMD: power inductors.

hot fix 2 of 4

  1. Board Outline, declared in stackup, but rendering to no "loop", i.e. no surface, can cause a crash. A simple bug fix it is not enough, as the resulting PCB will be simply empty - that is confusing
  2. Grouping tracks/pads/etc... into groups of overlapping objects. Creating the copper netlist and separating objects for geometry calculation. In case of 2 outlines (polygons) touch test, one of the segments of one of the polygons was spiked, in most of the cases. It was a kind of "how was it working at all?" error. One victim, as far as I know.
  3. Inability to detect the footprint features will no longer result in an exception (crash), but just an undetected component type.
  4. Crash when saving .zofzproj file containing a sparse BOM table.
  5. Reading BOM component designator ranges, like: "R1, R5-R10, R15-R17"

hot fix 1 of 4

  1. Fixed problem witch the IPC356 parser option: "Long ID/Pin name correction". The option allows to read an non compliant file, where component id and pin name text are longer then assigned space in the ipc356 specification. The option is enabled by default. Lines containing a "M" marker are not read, also from the compliant files, if this option was enabled.
  2. The shape recognition algorithm was unable to find pin "1" in case there were only non-plated holes in a component. Such condition could be caused by above bug. Uninitialized value was used as index, causing a crash somewhere later in the execution, because of a memory corruption.
  3. In some rare cases, rendered PCB, saved as a ".zofzproj" file, was corrupted.
  4. Component geometry detector crash on some complicated BGAs.

features

  1. BGA/PGA components packages.

 

ver 1.0.0 ()

Download

features

  1. Freemium model - Gerber Viewer is free, Component Modeler is premium.
  2. More components in the modeler: QFN/DFN, 4/5-Bump, 4-pin SO and DIP, 4/2-pad chip-crystal, push-button...
  3. Micro Via display, including buried vias and micro via netlist check.
  4. Improved hole metallization display, added separate internal and external surface.

fixed bugs

  1. Non-plated holes are removing copper now, as plated holes do.
  2. Zero length tracks - still some annoying problems fixed.
  3. IPC356 sometimes contains burred vias, "no-copper" error was shown.
  4. Jump to a single via node (not containing a component pin) was a jump to (0,0)

 

ver 0.9.107 ()

Download

hot fix

  1. Component recognition crash on complex packages,reading IPC356.
  2. Single layer board volume (core) - wrong thickness calculation (zero=transparent) when no mask or silkscreen.

 

ver 0.9.105 ()

Download

hot fix

  1. Gerber read: Zero sized straight track segment removal removes one more legit track.
  2. Rendered Board (.zofzproj) Save/Load when no components are present bug.

 

ver 0.9.103 ()

Download

features

  1. Added right panel check-box allowing to disable display of holes and board edges, named "Verticals".
  2. Added drill file settings, allowing for stacked vias, µvias, filled vias. Copper layers and netlist are handled properly. Vertical elements of the new via styles, still need to be added.

fixed bugs

  1. Single layer board volume (core) - wrong thickness calculation (zero). The pcb-volume is assumed to spread from bottom surface of top copper to top surface of bottom copper.
  2. "Opaque" marking of the color setup slider should be on it's right side
  3. Component Library, single row multi-pin (>3) THT components, like SIP-4 or TO-220/5 may have not correctly ordered pins. The problem is visible by net / pin selection.
  4. Gerber read: Zero sized straight edges of polygons can be misinterpreted, especially if the given polygon contains only zero sized straight edges (and is therefore a null object).

 

ver 0.9.100 ()

Download

feature

  1. Component Modeler License check instead of time limitation of the Component Modeler functionality.

 

ver 0.9.025 ()

Download

fixed bugs

  1. Zero sized drill used for routing (actually a meta information drawing on the drill "layer") caused a crash.
  2. Gerber flash without giving any new coordinate was ignored. Example: flash at the end of track, without repeating the coordinate.
  3. Components having pins in the same place (a "virtual" component in the particular case) crashed the component shape detection.
  4. [Set Equal Spacing] button in Board Outline "layer" in stackup dialog was not updating the stack display thickness values, when no extra core layers needed to be inserted.

 

ver 0.9.023 ()

Download

hot-fix

  1. PLCC case pin-netlist shift bug.
  2. UI improvements: mouse LMB click on component/pin when Netlist or Components dialog is open.
  3. Mixing RMB popup menu Model and Component List dialog editing could cause a crash.

 

ver 0.9.022 ()

Download

hot-fix

  1. Crash on running Netlist/Test, when a net selection is open.
  2. Hidden component right-click list broken.
  3. Component search/edit UI bugs.
  4. Component editing is now immediate. A separate dynamic mesh buffer for the edited component is implemented.

 

ver 0.9.021 ()

Download

hot-fix

  1. Sometimes calling the Model Menu can crash the program. This happends after removal of the model menu, by poping up some other dialog.
  2. Gerber stray space character after '*' star character.

 

ver 0.9.020 ()

Download

features

  1. A lot of new component classes are added to the internal library.
  2. Menu system for selecting component types and adjusting component parameters.
  3. Mathematical operations for aperture macro definition: unary "-" and "+" and parentheses "(", ")" are added, as defined in GerberX2.
  4. Some file names are longer then dialog box - implemented horizontal scroll bar.
  5. Option to sort files by date/time.
  6. Lighting - simple ambient and difuse light dialog.
  7. CAM_Load_Rules - added sections OrCAD (Alexiej) and Cadence Allegro (Benjamin).
  8. CAM_Load_Rules - must be more visible - added edit button in the autoload dialog.

bug fixes

  1. Aperture Macro rotation center adjusted to the new clear Gerber definition.
  2. Aperture Macro rotation for circle added as option - defined by GerberX2.
  3. Save/Restore of the program window position and size may permanently prevent the program from starting, if minimized or otherwise inactive window position is saved. The Direct3D can initialize only in visible window - program was exiting with Direct3D device error.
  4. There was a hot-fix for old PCAD inserting space characters in Gerber files. The hot-fix was also removing spaces in G04 (comment). That was making problems when the comment string was starting with digits. eg. G0433...)
  5. Excellon routing offset matching to Gerber was not working. Slots could disapear or be miss-placed.
  6. The macro definition was not flattened before it's use. Negative drawing was preserved and was destroying parts of drawing outside the macro.
  7. Very short arcs were replaced by a full circle. This condition detection is now set to trigger on equal points only.
  8. Irregular pinout (via IPC356) could hang the program.

bug fixes

  1. Adding step and repeat have been changing ".zofzproj" format. This should have been accompanied with the .zofzproj version being incremented. I missed this. Unfortunately ".zofzproj" files which are saved by version 0.5.0015, are unreadable by any other version.

 

ver 0.5.0017 ()

Download

features

  1. Window position is stored in registry and restored on the program start.
  2. Easy switching between Display and ManualEdit of the stack file assign dialog.
  3. Random color generator for net colors is connected to net names, if IPC356 is loaded.
  4. When IPC356 is loaded, net color edits are stored in the .camset file, related to the net names.
  5. Zipped Gerbers-set file input. Unzipping (and zipping) is transparent to all browsing functions, including New/Auto
  6. Step and repeat for Gerbers and NC-drill files (finally).
  7. Single Layer Mode is activated by Ctrl + left mouse button click on the layer enable check-box now. That replaces Double-click activation.
  8. Freemium Stub
    1. Components visualisation is divided in 2 levels: Extruded models (free) and Model Tables (premium).
    2. STEP component models, when implemented, will belong to the premium part.
    3. Premium functionality is temporary free, till March 1, 2017.

bug fixes

  1. If the program window dimension changes, or is in any other way recreated, during the triangulation phase, the program crashes.
  2. Samba folders were not sorted. Actually there was no file-list sort at all.
  3. Buffer overrun in Auto-offset. Histogram bins max value "512.0" instead of "511.5" and "round" used for speed.

 

ver 0.5.0015 ()

Download

features

  1. Reading of the BOM file. Component info is displayed on the right plane.
  2. Tabelarized Component Library, autodetection. In case a component is not identified, the former "extruded" form is displayed. The component tables are stil under development. Currently, implemented are: L-lead (QFP, SO, SOT, DPACK), J-lead, DIP, chip capacitors (resistors).

bug fixes

  1. GUI bug - folder selection crash. I could not see it for a long time, but it seems I have fixed it with your help.

 

ver 0.5.0012 ()

Download

features

  1. Cross-Section of the PCB and components. Use "DEL" key, also measurement maker(s).
  2. Hole diameter display (was forgotten while in the implementation).
  3. Wheel zoom movement time constant setting in "Navigate" menu. Plus shift-key speed modifier. Ctrl and shift works also for keyboard controlled movements.
  4. Possibility to switch off auto-offset matching for drills and IPC356. Priority for zero offset if matching, in this case, is detected.

bug fixes

  1. PCB Outline processing, finding the correct outline, in case of multiple "T" connections, can explode in time or memory usage - possibly leading to crash. This often hapends if some tracks are misinterpreted as outline (in wrongly set meta drawing) or when mutlipe lines are not finised to exactly the same point.
  2. IPC356 autodetection of rotation angle units, when radians are used. Why to use radians anyway if there are only 3 digits of precision assigned for rotation?! 90deg=>157=>89.954deg
  3. Netlist related operations could crash if there were no components on a bottom side, in some cases.
  4. Removal of board outline of rendered board caused crasch.
  5. But report tool can handle "portable version" stored log file.

 

ver 0.5.0008 ()

Download

features

  1. More layer types can be used in the CAM_Load_Rules.txt - autoload script. Layers can be defined in each section. When particular section is used as a rule for filenames, associated layers are added to the program. Alternatively, layer types previously defined in the Stackup / More Layer Types can be used. See the description inside CAM_Load_Rules.txt

bug fixes

  1. If last object in an object list flattens to nothing, some other objects may be removed.
  2. Board outline containing sequentially equal points may cause crash.
  3. Board outline path selection could create empty loops by going back and forth the seme lines, in some cases.
  4. IPC356: if the 317-Through-Hole line entry was used to describe a SMD feature, it was read incorrectly, causing the Component-Mesh-Modeler to crash.
  5. IPC356: unnamed nodes are assumed to be not-connected. The node name is automatically generated in form: " N/C_nnnnn". The same should be done to nodes named "N/C".

 

ver 0.5.0006 ()

Download

features

  1. Right mouse button drag moves the PCB.
  2. IPC356 does not contain information about THT component placement side (top/bottom). It is now possible to swap those components to the bottom side. Use right mouse button click on selected component.
  3. It is possible to hide unwanted components individually. Use right mouse button click on selected component.
  4. State of component hide and swap is saved together with the PCB stackup and rendered board files.
  5. Possibility to add more layer types. Acces via Menu: Stackup / More Layer Types. The extra types are saved together with stackup (.camset) and with rendered project (.zofzproj).
    Loading stackup file, adds to current set of layer types. Loading rendered project overwrites the types set.
    Layer types alone, are saved and loaded together with the Color Presets.
  6. All colors preset is saved and restored by stackup and rendered board files.
  7. Beside above, rendered board save/restore contains: state of layer enable checkboxes, the Component checkbox, the Hollow checkbox and saved camera positions (0..9)

bug fixes

  1. Semitransparent Solder Mask was drawn twice in the Hollow mode, possibly reducing the frame rate.
  2. Semitransparent Solder Mask transparency (alpha) value was reversed in the Hollow mode.
  3. Portable version cannot access its init file. Parameters are not saved for the next time the program is open. The path to the file is changed, by error, to the c:\windows directory and therefore not accessible without administrative privileges.
  4. Sometimes, when routing and drills are on separate files, auto-fit drills to Gerbers fails. One of the drill files is shifted or not visible.
  5. Overlapped, but not continuous routing on the drill "plate" may lose some of its components.

bug fixes

  1. Gerber parsing: resistance to missing coordinate number, assumed 0.
  2. Excellon parsing: linux style end-of-line character disturbed VC file seek exactnes - multipassing errors.

Download

features

  1. Menu changes:
    1. view / net selection effect
    2. netlist / crosscheck - function of CPN keys
  2. Keys:
    1. CPN, C, for crosscheck versus measurement selection
    2. Ctrl */ rotate to the nearest rectangular rotation
    3. Home rotates to the nearest rectangular position
    4. Ctrl-Home, rotates to zero angle - as Home before
  3. DialogBoxes:
    1. Screenshot directory and use-project-directory check box
    2. Dialogs are not 'transparent' for the mouse click or drag
  4. Component Display Feature.
    At the moment, the only information about component is taken from IPC356 file. Components are represented by set of basic shapes: cube, pin/cylinder, rect-chip-filling. The actual component shape selection is guessed, based on e.g. component designators. (see IEEE 315 or Wikipedia). Also the THT component layer is always assumed to be TOP.
    Therefore, urgently, more features must be added:
    • Reading IDF (or BOM) file - identify component, footprint, THT-layer.
    • Component options: component disable switch or transparent switch.
  5. Related to above, component mouse selection and component's shadow mouse selection in case of disabled components.
  6. Clear selection and display rule: Selected Object and Hoover Object.
    Selected object, if used, takes over the right panel display. The hoover display is back after de-selection, e.g. esc key.
  7. Orthogonal camera screen-shots are now physically scaled (DPI).
  8. Cross-Check - direction Orcad->ZofzPCB and ZofzPCB->Orcad. (orcad needs a script).
  9. User Interface scaling - 4K displays or higher DPI displays.
  10. Flattening crash recovery.
  11. Several sections of CAM_Load_Rules.txt are added.

bug fixes

  1. Drill/Gerber fitting problem.
  2. Loading Gerber, possible infinite loop.
  3. Loading Gerber, Regular Polygon ADD..P predefined aperture, rotation not converted to radians.
  4. Loading IPC356, more tolerant file parser.
  5. Loading IPC356, empty file crash (example: no components and pins).
  6. Loading Excelon, cannot recall.
  7. Some settings were not saved to registry.
  8. Some features (e.g. distance markers) were not working correctly in Orthogonal camera.
  9. Issue with single layer board without plated holes.
  10. Auto-Loading a PCB without defined outline may cause crash by memory read exception.
  11. Auto-Loading a PCB with only one copper layer does not insert a core layer.
  12. PCB with only one copper layer have wrong displayed board edge thickness.
  13. Strange display artefact - That is division by zero (or even 0/0) in the vertex shader.
  14. Auto-reading (composing) from only a drill file will now add a bare core to the project. Also bug about negative board outline.
  15. If excellon Guess Option is dissabled, vey likely a bug will render all positions to zero.
  16. drills without any copper layer are rendered incorrectly (bottom of the box), minor visual problem.
  17. Statistical Guessing of the trailing or leading zeros is added in excelon.
  18. drill from/to coper number wrong display bug fixed.

features

  1. AutoLoad suggests the path and name for saving the .camset file.
  2. Camera FOV (Field Of View) setting and orthogonal projection setting.
  3. Objects clearly outside of the Board Outline are removed.

bug fixes

  1. Introducing a new features in the netlist-browsing, I have managed to block the old one.
  2. ESC-key is not stopping the autopilot, but it is expected to.
  3. New version check function contact the website via wrong port (443 instead of 80). Till now that was working. Due to some kind of update, my provider has removed this redirection. I will make a notice about the new version release via the website and the social media.
  4. Above problem also disables the bug report tool.
  5. Auto-Load fail when simplified algorithm - could not decide gerber or excelon, after 20 first lines.
  6. If two outlines follow directly each other in the Gerber file and first point of the second is equal to the last point of the first then those two outlines will be connected. If the outlines overlap, XOR will be then applied instead of ADD.

 

ver 0.4.0004 ()

Download

features

  1. "Netlist/Nodes (PCB)" and "Netlist/Nodes (IPC356)" board browsing. The difference between those two methods plays role in case of discrepancies between PCB-detected netlist and IPC356 netlist.
  2. Reading the board outline from copper layers in addition to former method, that is using a separate layer. Meta image is distinguished from the layer image by using "impossible" thin tracks. The "meta-way" is now officially accepted by the Gerber Specification.
  3. Auto-Load works from a command line parameter if you specify just the folder path. If you specify a file of ".zofzproj" or ".camset" type, it is also loaded, as it was before.
  4. Automatic adding of core/prepreg in between copper layers, when [Set Equal Spacing] in BoardOutline / Thickness is pressed.

bug fixes

  1. Drill routing of more complicated shape, a multi-segment path, does not store mesh reference. Trying to highlight some nets (jump net, error, pin) can cause program crash.
  2. Drill routing of more complicated shape, a multi-segment path likely causes false positive detection of short circuit.
  3. False warning about unsaved work on program exit.
  4. Aperture Macro Comment not implemented. When encountered, causes syntax error: "Macro Primitive Type ?"
  5. False positive error: "Aperture Macro argument undefined."

features

  1. Changed format of .zofzproj file.

bug fixes

  1. Loading a rendered board (.zofzproj). if a layer is above some nomber of triangles, corrupted image is displayed.
  2. Macro expansion: add and subtract error - multiply and division is ok.

 

ver 0.4.0002 ()

Download

features

  1. Gerber Image Polarity "Force Negative" and "Force Positive" setting in addition to existing "Default Negative" and "Default Positive" settings.
  2. Auto-file-detection checks file content to be Gerber for layers and Gerber or Exelon for drills. This modification solves ambiguous sections, e.g. Protel99se v.s. Kicad "drl" and "txt" - Protel creates "drl" files in a rare binary format, whose could be taken as Kicad excellon drill files. This functionality is a stub for GerberX2 "%TF.FileFunction" - based autoload.Gerber X2 logo
  3. Some Gerber export modules can generate longer numbers (more digits) than format declared in the same Gerber file header. Workaround is possible in case of trailing zeros removal mode.
  4. edit box functionality: home, end, left, right, shift keys are operational.

bug fixes

  1. PCB outline drawing conversion to polygon: - non-closed shape correction range bugs:
    1. added range setting not working (view/sender effects/pen rad enlarge)
    2. added range setting applied only on already connected lines
    3. limit-rectangle (speed-up technique) rounding errors
  2. PCB outline crash when more than 800 lines
  3. Error-stop on depreciated Gerber command G55
  4. Hollow border can produce overlapping circles - sometimes visible e.g. on semitransparent solder mask

features

  1. Beside signed installation package, there is a companion version, running directly from a folder, without installation and associated privileges. It keeps all settings and examples in the same directory, whenever you place it.
  2. Two more color presets from Christian Weidner, including OSHPark purple.
  3. Ultra High resolution screenshots. x1 (current resolution) to.. x10 19200x10500. download example
  4. Gerber parser allows for Gerber X2 codes: %TF %TA %TD codes, but ignores its content. You can read Gerber X2, but ZofzPCB makes no use of the new additional information at the moment.
  5. Still not correctly interpreting board outline drawing when using single line as a board cut-out. this can happen in panelisation. Example: two rectangles, one inside the other, form a frame shape. This may be not intended.
  6. Additional syntax in CAM_Load_Rules.txt autoload script:
    • Plated/Non-Plated option (Drill_PTH/Drill_NPTH).
    • drills from-to assignment.
  7. Added section "Mentor" and section "Proteus" to the CAM_Load_Rules.txt autoload script.
  8. Added Mentor specific Excellon drill size definition.

 

ver 0.4.0000 ()

I need some pleasure too. Feature-freeze dissolves. I have decided to add correct thickness for tracks and other layers. It is possible to switch it off in the view menu. This could be required if those additional triangles overheats your GPU, causing too low frame rate. This is now an official release.
I have arranged for code certificate. That is securing the install package transfer.
  1. I have 3 reports about error in the triangulation, it seems to be the same bug - transparency fade-out band extraction (used for preparing the hollow effect). It is related to creating band (or ribbon) inside big surfaces, in case of bumpy track drawing e.g. horizontal tracks only. I am still searching the solution faster then n^2. bumpy edge of dorizontal tracks
  2. Some old software does not generate Gerber image polarity parameter %IPPOS*% or %IPNEG*%. Therefore I have added "Def. Negative" checkbox. The checkbox defines image polarity in case the Gerber file does not declare it (default polarity). Now I found that there are some Gerber files simply declaring wrong image polarity. This is driving me crazy. What to do?
  3. Extremely long "flattering" time. Detailed description:
    for the "flattering" I am still using bounding rectangles to limit the edges crossing algorithm. It works for local and short tracks. But when it is not efficiently working, I have n^2 operations, and this can grow huge. The second stage (triangulation) I have already n*log(n) – scan line sweep algorithm successfully implemented. And I am planning to apply this to the first phase too. (edges are circles – that is the difficult point). So, n*log(n) is much faster then n*n, I have already seen this. (n is a big number.) Additionally, since I am using double precision and(especially for circles) I am using 3 value logic: (yes – no – do not know), there is a possibility that I need to solve binary equation system to meaningfully decide what edges are staying and what are removed. Sometimes it takes a very big matrices to solve (n^3 for the Gaussian back-substitution algorithm)! Solution for this is a double-double arithmetic package – a very cool approach, using pair of double numbers to have almost quadruple precision. This should minimize the ‘do-not-know’ state, as it did in triangulation.
  4. Spaces (character 32) in the Gerber files are forbidden by format definition. But somehow, there are Gerber files containing spaces, as I have seen, in the aperture definitions.
  5. Gerber file read, statements like: $1=$2+$3 - there is a chance of exception.
  6. Lack of pads or IPC356 test-points on one side and simultaneous lack of THT pads-test-poins causes auto-scale and auto-offset calculations for IPC356 fail, placing components and test-points almost at infinity.
  7. IPC356 Load errors were not displayed.
  8. Multiple IPC356 netlist test-points definitions on a single place could cause problems by error browsing.
  9. Only first type of IPC356 errors were displayed correctly. Next sections listings interpretations were shifted.
