CLK-30001: Gated Clock is Not Feeding at Least a Predefined Number of Clock Ports to Effectively Save Power


A design should not contain a gated clock that drives fewer than the predefined number of clock ports.


Name Default Value Description
Clock_Pin_Threshold 10

Minimum number of clock pins that the gated clock should drive to save power efficiently. Specify this parameter in the Parameters field of the Design Assistant Settings dialog box.


To effectively reduce power consumption using gated clocks, ensure that all gated clocks in a design drive at least the predefined number of clock ports. Consider the following examples of a gated clock that feeds more than the predefined number of clock ports:
