Express does not preserve instantiated FMAP / HMAP / LUT primitives
Record #4395
Product Family: Software
Product Line: Synopsys
Product Part: FPGA Express
Product Version: 2.1.1
Problem Title:
Express does not preserve instantiated FMAP / HMAP / LUT primitives
Problem Description:
Urgency: Standard
General Description:
FMAP and HMAP primitive instantiations are ignored by Express. The corresponding logic
is implemented properly. The same is true for Virtex LUT instantiations.
Solution 1:
Do not use FMAPs, HMAPs or LUTs in your HDL code; infer combinatorial logic and
FPGA Express will infer the gates and mapping information.
This issue will be addressed in an upcoming version of Express.
