7.1i ISE - Generated Timing Reports are not coincident in Speed Grade

描述

Keywords: ISE7, Project Navigator, ProjNav, Timing, Report, Speed, Grade

Project Navigator did not generate a timing report with the proper speed grade.

After I change the speed grade of the device and re-implement the design, the generated design is still based on the original speed grade. This is the case even after project cleanup or other operations.

解决方案

To work around this issue, perform the following:
1. Run the "Analyze Post-Place & Route Static Timing (Timing Analyzer)" under the Project Navigator GUI, or run the Timing Analyzer standalone.
2. Select "Analyze Against Timing Constraints", the result will be OK.
The proper timing report will be generated based on the selected speed grade.
