Timing analysis is the static verification that ensures your design behaves predictably when loaded and run on hardware. It accounts for manufacturing and environmental variations, which are captured in delay models grouped by timing corners and corner variations.

To verify your design, you need to analyze timing against all recommended corners. For each corner, perform all checks under the most pessimistic conditions. Your design must pass the following four analyses:

  • Max delay analysis in the slow corner
  • Min delay analysis in the slow corner
  • Max delay analysis in the fast corner
  • Min delay analysis in the fast corner

Each check uses delays that reflect the most pessimistic scenario. The tool always associates the following checks with specific delay types:
