When physical optimization is skipped on a candidate primitive cell, the PHYS_OPT_MODIFIED property of the cell is updated to reflect the skipped optimizations. When multiple optimizations are skipped on the same cell, the OPT_SKIPPED value contains a list of skipped optimizations.
- Architecture Support
- All architectures
- Applicable Objects
- The PHYS_OPT_SKIPPED attribute is placed on the cells.
