CLK-30001: Gated Clock Should Feed a Predefined Number of Clock Ports for Power Efficiency
Description
To effectively reduce power consumption using gated clocks, a design should not contain a gated clock that drives fewer than the predefined number of clock ports based on the parameter "clock_pin_threshold".
Parameters
Name | Description | Type | Default Value | Min Value | Max Value |
---|---|---|---|---|---|
clock_pin_threshold | Clock Pin Threshold | integer | 10 | 1 | |
clock_spines_data | Clock Spines Threshold | integer | 25 | 1 |
Recommendation
Ensure that all gated clocks in the design drive at least the predefined number of clock ports. The following example shows a gated clock that feeds more than the predefined number of clock ports:
