Hello, together with @Mario Romero, @Francisco Aguirre and @Lucas Irribarra Zúñiga we are trying to submit our design via the Efabless platform, but the precheck is generating OEB errors. The main error type that calls our attention is "ERROR: No model match...", referring to devices from the PDK library. Do you have any idea of what we could be doing wrong? I attached our OEB log file. @Mitch Bailey @Tim Edwards @jeffdi @Anton Maurovic (efabless support)

@Jorge Marin Thanks for reporting this. The quick, local fix is to add the following line to

$PRECHECK_ROOT/checks/be_checks/tech/sky130A/cvc.models

MP sky130_fd_pr__pfet_g5v0d16v0 Vth=-0.2

Unfortunately, even if it passes the local check, the platform check will most likely fail and you’ll need to ask efabless to override the precheck failure. Sorry for the trouble. I’ll create a PR for the platform precheck after tapeout.

Thanks @Mitch Bailey for your reply. Do you know how can I get this overriden by Efabless, so we can proceed to tapeout?

@Jorge Marin I’ll ask and get back with you.

Ok, thanks a lot @Mitch Bailey!
