This section provides a summary of all the Bus Skew constraints, with their requirements, the actual worst bus skew, and slack for each constraint. The summary table can be used to quickly see whether any of the Bus Skew constraints is violated.

Figure 1. Report Bus Skew: Summary Section

The Constraint table column represents the timing constraint position number that matches the position number reported inside the Timing Constraints Editor (TCE).

The From and To table columns include hyperlinks to the objects specified inside the set_bus_skew command. The objects can be cells or pins. It is possible to click on the hyperlinks to select all the startpoints or endpoints of a specific Bus Skew constraint. After the objects have been selected, the schematic can be opened with F4.
