12/08/2023, 10:22 AMIts not working. The pin it shows is different. When I checked with [get_pins *] command, in OpenLane, It give some kind of numbered pins [ex pin_01234_x].

12/08/2023, 8:22 PM@Munjani Jayesh it is highly likely that your hierarchy is being flattened. You need to find the flat name to constrain the clock on. Or, you need to turn off synthesis flattening for that module in Yosys.
