#1236 Incorporate JSON metrics report from OpenROAD into OpenLane Issue created by ravi-varadarajan OpenROAD currently dumps out metrics in JSON format with the use of -metrics <metrics_file_name>. There are also dedicated tcl commands to dump out the area/timing/power metrics which can be called during the various stages of the flow. We would like to modify the OpenLane scripts to use the -metrics option when invoking OpenROAD and also update the tcl scripts to set the design stage and invoke the appropriate metrics reporting functions. Once the final stage is done, we will need a utility function like genMetrics.py in ORFS to aggregate all of the metrics. I can help answer any questions regarding the changes required The-OpenROAD-Project/OpenLane
