02/18/2025, 9:38 PMORFS (OpenROAD Flow Scripts) is a flow which uses both Yosys and OpenROAD to do RTL to GDS. You have posted an issue with Yosys. We don't support issues with Yosys unless they come from running ORFS.

02/20/2025, 2:24 PMFor what it's worth, the root cause is you used a single asap7 .lib file, one that only describes flops and latches (hence the seq in the name), which is useless for the purpose of technology mapping with abc, which deals with combinational logic only. There are multiple asap7 .lib files that all have to be used to successfully synthesize the typical design and ORFS merges them together for you
