LogiCORE FIR Compiler v6.0 - Why does my multi-column FIR Compiler implementation fail to route?

Description

Why does my multi-column FIR Compiler implementation fail to route?

Solution

Changes were made in the FIR Compiler to improve the utilization of the DSP48s and reduce the number of filters that would require multiple columns. 

This caused multiple column filters to break and not to properly route.

This problem affects the FIR Compiler v6.0, v6.1, v6.2 and will be fixed in a future release of the FIR Compiler.
