TMC-20207: DSP Blocks with Unregistered Inputs that are the Destination of Paths Failing Setup Analysis


Violations of this rule identify DSP blocks with unregistered inputs that are destinations of paths that fail setup analysis. Registering DSP inputs can significantly improve DSP's μtsu/cell delay.


Name Description Type Default Value Min Value Max Value
maximum_setup_slack Reports a violation for timing paths that have a setup slack below the value of this parameter. double 0.0    


Add pipeline(s) to the DSP's input paths to register DSP's inputs. Also make sure DSP packing rules are not violated to allow successful register-packing. Review the Fitter reports 'Fixed Point DSP Register Packing Details' and 'Floating Point DSP Block Details' for more details.
