: Using set_false_path and set_multicycle_path to prevent the tool from wasting effort on non-critical or multi-cycle routes.
Before 2021, optimizing for 16 corners meant 16 separate runs. The 2021 guide details how to use to reduce runtime by 40-60%. synopsys timing constraints and optimization user guide 2021
