CLK-30001: Gated Clock is Not Feeding at Least a Predefined Number of Clock Ports to Effectively Save Power
Description
A design should not contain a gated clock that drives fewer than the predefined number of clock ports.
Parameter
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. |
Recommendation
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:
