Reproduction Material

• Upload a tarball containing the relevant design. multi_encoder_prj.zip

• List the commands used to run the design. Extract zip file and place multi_encoder_prj inside OpenLane/designs/ Inside OpenLane container: % ./flow.tcl -design multi_encoder_prj

Expected behavior

run_synthesis should be passed
