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
