Why does my FIR Compiler v2.0 Core with reloadable coefficients fail to generate in CORE Generator using the ISE 9.1i without any IP Updates?
A function necessary to complete generation of FIR Compiler v2.0 cores with reloadable coefficients is not available in the initial ISE 9.1i release.
There are 2 possible ways to work around this issue:
1. Download and install ISE 8.2i with IP Update 2 or IP Update 3.
2. Download ISE 9.1i IP Update 1.
Available March 2007.
