6.2 Analyzing Your Design

The timing engine uses the following priorities when analyzing paths and calculating slack:

  1. False path
  2. Max/Min delay
  3. Multi-cycle path
  4. Clock

If multiple constraints of the same priority apply to a path, the timing engine uses the tightest constraint.

You can perform two types of timing analysis:

  • Maximum Delay Analysis
  • Minimum Delay Analysis
To perform the basic timing analysis, use one of the following methods to open the Timing Analysis View:
  • From the SmartTime Tools menu, choose Timing Maximum Delay Analysis or Minimum Delay Analysis.
  • From the SmartTime window, click the ??? icon for Maximum Delay Analysis or the ??? icon for Minimum Delay Analysis.
Note: When you open the Timing Analyzer from Designer, the Maximum Delay Analysis window appears by default.
