LogiCORE FIR Compiler v1.0 - Why does COREGen issue an error when the column length is larger than 64 XtremeDSP Slices, when targeting a Virtex-4 FX device?

Description

Why does COREGen issue an error when the column length is larger than 64 XtremeDSP Slices, when targeting a Virtex-4 FX device?

Solution

This is a known issue, and the current multi-column support on the FX100 and FX140 Virtex-4 parts is limited to column lengths of 64, rather than the maximum possible column length of 80 or 96 in the respective devices.
