XST - "WARNING:Xst:643 - Multiplier result width is N bits"

描述

General Description:

During XST synthesis, the following warning occurs:

"WARNING:Xst:643 - Multiplier result width is N bits."

解决方案

This warning occurs when the maximum width of an inferred multiplier is not created.

Given the following:

C = A * B;

width (C) = width (A) + width (B)

when the width of C is less than the sum of the widths of A and B, that width will be represented by "N" in the warning.
