(unrelated to my previous question) I have a design that hangs openlane during synthesis. it doesn't crash, it pegs one CPU at 100% for at least 7 hours before i get tired of waiting and kill it. the log output stops growing mid-line. where can i file this bug?

Which

SYNTH_STRATEGY

is used?

possibly i am running into the same issue as this: https://github.com/The-OpenROAD-Project/OpenLane/issues/1514

Try

DELAY 4

if facing issues with

DELAY 0
