#1607 Add metrics generation to track QoR Issue created by vijayank88 Description OpenROAD supports metrics generation to track QoR. Command:

./openroad -metric file.json

Metrics.tcl

available here Implement metrics generation for OpenLane flow as well. Proposal Sample

metrics.json

for floorplan stage:
