Description

The advanced analysis and default analysis report the maximum frequency differently; the report from TRACE using the "-a" option differs from the report from TRACE using the "-u" option.

Solution

The default analysis includes pad-to-setup paths in the calculation of the overall period/frequency of the design, while the advanced analysis does not include pad-to-setup paths. 

NOTE: TRACE uses the default analysis if an option is not used.
