AR# 45211

AutoESL- No DSP48 reported in AutoESL synthesis report

Description

The AutoESL report shows no DSP48 primitive used.

Instead, MULT18x18 primitives implementation is high.

Solution

AutoESL 2011.3, 2011.4, and 2011.4.2 incorrectly report DSP48 usage as MULT18x18.

For accurate usage information, refer to the HDL synthesis report for better estimation and the actual implementation report for exact resource utilization.

This issue is fixed in 2012.1 AutoESL.
