Hi, everyone.
I want to input the floorplan information of Encounter to DC(topographical_mode) to improve the timing of the design. The floorplan information is DEF file format, and it can be read into dc -topo by extract_physical_constraints command correctly, and the "compile_ultra -scan -num_cpus 2 -timing_high_effort_script -congestion" was executed correctly. But when the optimization finished, the tool shown the following error and exit. Can anyone help me about it? Thank you
Error: Fail in placement: Over Utilization
Severe Error: Fatal error: Placer did not complete. (PSYN-375)
Error: DC Topographical Failed to place the design. (OPT-1405)
Error: compile_ultra Topographical stage has abnormally terminated. (OPT-100)
Best regards!
