LogiCORE FIFO Generator v3.1 - Is a Nonsymmetric Aspect Ratio of 1:8 Supported?

Description

Page 60 of the FIFO Generator v3.1 User Guide (UG175) states that you can have a nonsymmetric aspect ratio of up to 1:8; however, if you choose Independent Clocks, BRAM, you can not select an input width of 16 and an output width of 128, why?

Solution

This is a result of a GUI issue of FIFO Generator v3.1. It has been fixed in v3.2, which is included in IP Update #2 for ISE 8.2i.
