AR# 4395

2.x FPGA Express - FPGA Express does not preserve instantiated FMAP/HMAP/LUT primitives

説明

Keywords: Foundation Express, FPGA Express, FMAP, HMAP, LUT, EQN, instantiate, primitive

Urgency: Standard

General Description:
FPGA Express ignores FMAP and HMAP primitive instantiations. (The corresponding logic is implemented properly.) The same is true for Virtex LUT instantiations.

ソリューション

Do not use FMAPs, HMAPs or LUTs in your HDL code; when you infer combinatorial logic, FPGA Express will infer the gates and mapping information.

This issue has been resolved in FPGA Express versions 3.4 and newer.
