疑问描述

Keywords: FIFO, BRAM, utilization

The numbers I see reported for BRAM utilization in the overall map utilization and the module level utilization do not add up. Is this a known problem?

解决方案

There are known problems with the module level utilization report when FIFO and BRAM instances are packed together in a single component. The utilization is under reported in ISE version 10.1, and over reported in 11.1. This will be fixed in version 11.2.
