Figure 1. Report Bus Skew: Summary Section

This section provides a table that summarizes all set_bus_skew constraints. For each constraint, it shows:

  • The requirement
  • The worst actual bus skew observed
  • The calculated slack

Use this table to quickly identify any bus skew violations.

Additional Table Features

  • The Constraint column shows the position number of the timing constraint. This number matches the one in the timing constraints editor (TCE)
  • The From and To columns include hyperlinks to the specified objects (cells or pins) from the set_bus_skew command
  • You can click these links to select all startpoints or endpoints associated with a specific constraint. After you select it, press F4 to open the schematic
