Vivado Timing - Where can I find the Fmax of a clock signal in the timing report?

Description

Where can I find the Fmax of a clock signal in the timing report?

Solution

The Fmax value of a clock signal is not explicitly given in the report_timing/report_timing_summary report. 

To calculate the Fmax, use the following equation:

Min Period = Actual Period - WNS

Fmax = 1/Min Period

WNS is the worst negative slack of the clock signal in the Intra-Clock Paths section.
