TMC-20053: DSP Inputs Driven by High Fan-Out Net
Description
DSP data inputs were driven by a net with fan-out more than a user configurable threshold (default 500).
Parameters
| Name | Description | Type | Default Value | Min Value | Max Value |
|---|---|---|---|---|---|
| DSP_HFN_Threshold | Fanout theshold for High Fanout Net (HFN) in DSP check | integer | 500 | 1 |
Recommendation
Remove high fan-out nets driving DSP data inputs. Circuits with high fan-out nets driving DSP inputs will have both routability and timing closure difficulties.
Severity
Low
