DSP48/A/A1/E/E1 Slice - Why am I seeing erratic behavior on the output?

描述

Why am I seeing erratic behavior on the output?

解决方案

This can happen if the DSP Slice is not properly constrained.

It is recommend that users seeing such behavior should thoroughly examine their constraints of the data paths feeding the DSP48/A/A1/E/E1 Slice.

It is also recommended that the user review the constraints on the output path of theDSP48/A/A1/E/E1 Slice, though it is more likely to be the input causing corrupted data to be latched into the registers.
