Place and Route Multi-Run Script

The efx_run_pnr_sweep.py Python 3 script can be used to run place and route multiple times in succession.

efx_run_pnr_sweep.py [--help] [--force] [--timingSumReport [TIMINGSUMREPORT]]
    project XML {sweep_seeds, sweep_opt_levels} [--start_seed [START_SEED]]
    [--num_seeds [NUM_SEEDS]] | --end_seed [END_SEED]]

Note: You can use efx_run_pnr_sweep.bat to run the efx_run_pnr_sweep.py script in the Windows Command Prompt.

Notice: Refer to Place and Route Options in the Efinity Timing Closure User Guide for more information on when to use this script.
