Hi,
I'am using Virtex II chips. In my design I have multiple multipliers,
for what I want use Hardware Multipliers. For Synthese use I Precision
from Mentor. To force using Hardware Multipliers I use attribute
DEDICATED_MULT = ON.
When I Synthesis only my Sub Module I get result what I want. When I
Synthesis design where my Sub module is instanced are my Hardware
Multipliers gone and replaced with logic. Can anyone comment?
Cheers,
TPalm
