Why do I see only one timing corner reported in the TimeQuest timing analyzer report?

If the multicorner analysis option is not turned on, the TimeQuest timing analyzer only reports timing information for one corner and labels it as Worst-Case Timing Paths. These paths may not be the worst-case paths over all timing corners.

To report timing for all timing corners, perform the following step:

• In the Quartus II software version 12.1 and later:

1. Open the Settings dialog box from the Assignments menu and select the Compilation Process Settings category.
2. Turn on the Enable multicorner support for TimeQuest and EDA Netlist writer option.

• In the Quartus II software version 12.0 SP1 and earlier:

1. Open the Settings dialog box from the Assignments menu and select the TimeQuest Timing Analyzer category.
2. Turn on the Enable multicorner timing analysis during compilation option.
