PHYS_OPT_MODIFIED

When physical optimization is performed on a primitive cell, the PHYS_OPT_MODIFIED property of the cell is updated to reflect the optimizations performed on the cell. When multiple optimizations are performed on the same cell, the PHYS_OPT_MODIFIED value contains a list of optimizations in the order they occurred.

Architecture Support

All architectures.

Applicable Objects

The PHYS_OPT_MODIFIED attribute is placed on the cells.

Value
