Why do I not see a resource estimation graph for my Floating Point operator function?
A graph showing resources and speed as a function of latency has been included in the Floating Point Operators GUI for v3.0. The resources are presented only for single and double precision adders and multipliers on Virtex-4, Virtex-5, and Spartan-3E. The resources are not available for any other combination of options in the Floating Point Operators v3.0 GUI.
