AR# 22936 LogiCORE FIR Compiler - Why can I not use the multi-column support when my coefficients are symmetrical?

Why can I not use the multi-column support when my coefficients are symmetrical?

This issue is a limitation of the FIR Compiler that is documented in the v2.0 and beyond data sheets. It becomes difficult to do folding when the coefficients are symmetrical, and thus multi-column support was implemented for non-symmetrical coefficients only.

This limitation has been removed in v6.3 and later.

Please see (Xilinx Answer 29138) for a detailed list of LogiCORE IP FIR Compiler Release Notes and Known Issues.
