LogiCORE Complex Multiplier v2.1 - Why is the option to use rounding not available in my multiplier?


When I attempt to create the Complex Multiplier v2.1 core, the option to use rounding is grayed out and truncation is automatically selected. Why?


Currently, the only architecture that supports rounding in the Complex Multiplier v2.1 core is Virtex-4. All other architectures default to truncation.

This issue has been fixed in v3.0 and beyond.
