We are happy to announce that a post-route timing evaluation with the OpenROAD parasitic extraction tool (OpenRCX) is now available. The following links give post-routing timing evaluation examples with OpenRCX+OpenSTA using four post-route designs from the IEEE CEDA DATC’s RDF-2020 calibration testcases. An example calibration flow for Skywater130 technology with OpenRCX is in the Script archive.
