LogiCORE Multiplier v10.1 - Why are the Block Memory resource estimations in accurate for my contact-coefficient multiplier with a large constant, and the large A input?

Description

Why are the Block Memory resource estimations inaccurate for a contact-coefficient multiplier with a large constant and a large A input?

Solution

This happens when the A input bit width is larger than 35 bits. You can obtain the correct resource usage information from the MAP report.
