Incremental Placement Summary

The following example of the Incremental Placement Summary includes a final assessment of cell placement reuse and run time statistics.

Incremental Routing Summary

The Incremental Routing Summary displays reuse statistics for all nets in the design. The categories reported include:

Fully Reused
The entire routing for a net is reused from the reference design.
Partially Reused
Some of the routing for a net from the reference design is reused. Some segments are re-routed due to changed cells, changed cell placements, or both.
New/Unmatched
The net in the current design was not matched in the reference design.
