2020-09-23Finished cleanup, fixed all pcbnew DRC errors reported. First attempt atPavel V. Shatov (Meister)
generating Gerbers. The result is somewhat surprising, since each Gerber is huge (10MB+). This turned out to be related to the way KiCAD fills copper polygons. Version 5.1.x that I use has support for some better pouring algorithm, while the 4.x version Fredrik used at the time of conversion had some different and obviously inferior pouring algorithm. I updated all the shapes to use the newer fill algorithm and this helped a bit, but didn't entirely solve the problem. Internal layers with large planes still produce very large Gerbers (~1MB), but they're more or less manageable now. Further research indicates there currently seems to be no way of further reducing Gerbers, see eg.: https://forum.kicad.info/t/gerber-files-are-too-large-due-to-thousands-of-drawn-features/17750
2020-09-23Renamed schematics sheets for consistency.Pavel V. Shatov (Meister)
2020-09-23Finishing cleanup. Fixed schematics DRC errors (mostly missing NC flags on somePavel V. Shatov (Meister)
of the pins of the newly added componets). Also updated pages to show "rev.04", not "rev.02"
2020-09-23Did some cleanup, also had to re-route VCC_PLL for iCE40.Pavel V. Shatov (Meister)
2020-09-23Entirely routed the design. Not useable right now, so far just reports zeroPavel V. Shatov (Meister)
unrouted nets. Will cleanup next.
2020-09-23Intermediate step, re-routing the design according to the changes in schematics.Pavel V. Shatov (Meister)
2020-09-23Almost finished doing edits to schematics. Added Lattice iCE40 UltraPlus FPGAPavel V. Shatov (Meister)
along with it's power subsystem and programming circuitry.
2020-09-23Continued doing edits. Removed AVR tiny tamper detection processor.Pavel V. Shatov (Meister)
2020-09-23Started editing the design. So far removed the old MKM component.Pavel V. Shatov (Meister)
2020-09-23Forward annotation (eeschema -> pcbnew) is now FULLY OPERATIONAL! Hoorah!Pavel V. Shatov (Meister)
2020-09-23Turns out multi-part components were not fully converted and were notPavel V. Shatov (Meister)
recognized properly during forward annotation. Had to do a couple of experiments to figure out how KiCAD handles this and then write some quick and dirty scripts to repair the multi-part symbols (STM32, Artix-7 and the 74_244 logic buffer were affected).
2020-09-23Fixed PCB footprint references. Basically had to just replace dashes withPavel V. Shatov (Meister)
underscores.
