Note: The Extend Analysis for All Paths option is currently only available for setup analysis.
The Path Characteristics are reported on the worst setup path along with the worst setup path to the startpoint cell (
PrePath) and the worst setup path from the endpoint cell (
-extend option incurs higher runtime as several timing analyses are required to collect the characteristics of all reported paths.
