Install KiCAD nightly build -to work with the Cryptech Alpha PCB.</p> - -<p>The schematics are mostly converted. A few components do not connect with their -nets (e.g. C9 and C10 on sheet rev02_01), but maybe a manual overhaul will be -needed anyways at the end of conversion. A bigger issue is that no components -get footprints associated with them in the schema, so generating a new netlist -won't work at all. The footprints exists in some form in the PCB, so we only -need to figure out how to reference them properly in the schema.</p> - -<p>All the copper layers convert reasonably well. The challenges are mostly -around filled polygons on the various layers. A python script (fix-pcb.py) -modifies parameters to get a fairly close result.</p> - -<p>I'm currently looking into ensuring the drill hole sizes are right, and the -non-copper layers have been largely ignored this far.</p> - -<h2>Issues</h2> - -<p>Two layers (Altium Gerber files CrypTech.G1 and CrypTech.G2) have fills -that I have not been able to reproduce. I targeted not missing any copper, -accepting that the KiCAD gerber fills reach more places, so add some copper -on those layers.</p> - -<p>Drill hole sizes have not been checked. KiCAD seems to add ~0.85 mil more -clearance around vias. This needs to be double checked but I'm hoping that -we can just tolerate that.</p> - -<p>Importing WRL files (3D models) required some hacking of the altium2kicad -tool that I haven't been able to work on upstreaming yet. Something is still -not right here, but the board does have a fair amount of component (including -the more special ones) in KiCAD 3D view.</p> - -<p>Another hack that has not been upstreamed is loading more of the source -files, IIRC to get all component footprints properly converted.</p> - -<p>The KiCAD board does not pass DRC checks yet. I believe part of this is -because design rule settings aren't (fully?) imported from Altium. Need -to figure out the settings used for this project, and fix all drill sizes -I think.</p> -``` - -[[RepositoryIndex(format=table,glob=user/ft/alpha_to_kicad)]] - -| Clone `https://git.cryptech.is/user/ft/alpha_to_kicad.git` | -|---| |
