When I run timing analysis on my design with IDDR and ODDR components, OFFSET IN and OFFSET OUT constraints, and the RISING and FALLING time group, one of the OFFSET constraints has 0 items analyzed. When is this going to be fixed?
This problem has been fixed in the latest 9.2i Service Pack available at:
