TMC-20207: DSP Blocks with Unregistered Inputs that are the Destination of Paths Failing Setup Analysis
Description
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.
Parameters
| 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 |
Recommendation
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.
