When logic optimization is skipped on a candidate
primitive cell, the OPT_SKIPPED 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 OPT_SKIPPED attribute is placed on the cells.
