the problem with this particular irate individual is that he's assumed that because TSMC's DRC rules are only accessible under NDA that automatically absof*** everything was also "fake open source".
idiot.
sigh.
clearly didn't read the article.
whilst both Staf Verhaegen and LIP6.fr signed the TSMC Foundry NDA, we in the Libre-SOC team did not. we therefore worked entirely in the Libre world, honoured our committment to full transparency, whilst Staf and Jean-Paul and the rest of the team from LIP6 worked extremely hard "in parallel".
the ASIC can therefore be compiled with three different Cell Libraries:
* LIP6.fr's 180nm "nsxlib" - this is a silicon-proven 180nm Cell Library * Staf's FreePDK45 "symbolic" cell library using FlexLib (as the name says, it uses the Academic FreePDK45 DRC) * the NDA'd TSMC 180nm "real" variant of Staf's FlexLib
i was therefore able to "prepare" work for Jean-Paul, via the parallel track, commit it to the PUBLIC REPOSITORY (the one that's open, that our resident idiot didn't bother to check existed or even ask where it is), which saved Jean-Paul time whilst he focussed on fixing issues in coriolis2.
it was a LOT of work.
