I am using SOC encounter for APR for the 1st time. It seems a LEF file is required for Floorplanning, but I cannot find any LEF in the std cell library. So can you please give me any hint ?Is LEF mandatory ?
Lef is mandatory as it has the size of the cell and the pin locations. If you have gds u can dump out a lef through cadence virtuouso. But lef is a must view.
