The maximum achievable frequency (Fmax) of a global clock network in Versal devices is dependent on the clock routing and clock extent. The Vivado timer automatically computes the Fmax for each clock net based on the clock routing and reports slack under worst pulse width slack (WPWS) in the timing summary report. If the Min Period constraint is met, no further action needs to be taken. Otherwise, the following recommendations will maximize the frequency that a global clock network can support.
