LogiCORE FIR Compiler v3.0 - Why are the results of my interpolating half-band filter incorrect when I use the optimize for speed option?

Description

Why are the results of my interpolating half-band filter incorrect when I use the optimize for speed option?

Solution

This issue is resolved in the FIR Compiler v.3.1. 

 

This issue is due to a bug in the way the center tap is created for interpolating half-band filters when the optimize for speed option is used. You can work around this issue by not using the optimize for speed option.
