This section provides access to the detailed timing paths for each Bus Skew constraint. There is an associated reference path that can be expanded for each timing path endpoint .

The bus skew calculation is:

Actual Bus Skew = Endpoint Relative Delay - Reference Relative Delay - Relative CRPR

Figure 1. Example of Detail Path for the First Endpoint and its Reference Path

It is possible to select a path and look at the detailed timing path report inside the Property pane. The schematic of the path and/or reference path can be generated by clicking the schematic icon and pressing F4 (the endpoint path and its reference path can be selected together).
