Agilex gated clock conversion - Agilex gated clock conversion Hello, I'm running Quartus 21.3 building for an Agilex FPGA. The clock gate conversion isn't working even though I have this set in the project file: set_global_assignment -name SYNTH_GATED_CLOCK_CONVERSION ON in the *.syn.rpt I see this message: Warning (20807): Automatic Gated Clock Conversion is enabled, but no clocks are explicitly identified and this family does not support automatic clock recognition during synthesis. Add GATED_CLOCK_CONVERSION_BASE_CLOCK assignments to properly identify base clocks. The SDC constraints don't seem to make a difference on the clock roots that I want converted. Furthermore, I haven't found a way for the tool to take the GATED_CLOCK_CONVERSION_BASE_CLOCK assignment. Any assistance would be appreciated. Replies: Re: Agilex gated clock conversion Thank you! This works. Replies: Re: Agilex gated clock conversion The Intel doc refers to source clock and then on entity, this is a bit strange: https://www.intel.com/content/www/us/en/docs/programmable/683296/23-1/analysissynthesisassignmentssynthgatedclockconversionbaseclock.html Shall it require at last a -to * ? Something like set_instance_assignment -name synth_gated_clock_conversion_base_clock on -to * Replies: Re: Agilex gated clock conversion Hi, [First Post Edited] Had to use both: set_global_assignment -name SYNTH_GATED_CLOCK_CONVERSION ON set_global_assignment -name SYNTH_GATED_CLOCK_CONVERSION_BASE_CLOCK ON Then Following design synthesis, view the results of gated clock conversion in the Gated Clock Conversion Details report ( .syn.rpt under Gated Clock Conversion Details ) . The report lists all converted and unconverted gated clocks with their base clocks. For unconverted gated clocks, the report specifies the reason the clock is not converted.
