Hi all, I’ve been playing around with the various tools out there and was wondering if anyone could shed some light on if there’s anything “special” that OpenLANE does to get DRC clean results for sky130? If I build, for example, the GCD example design in
https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts targeting sky130hd, I get DRC errors. However, it seems like both OpenLANE and the OpenROAD flow scripts are just wrappers over a Yosys->OpenROAD flow, so I’m curious if there’s anything in particular that makes OpenLANE give clean results, while OpenROAD does not (or does it just take a whole bunch of small tweaks combined?)
