How do I determine the level of Virtex-II multiplier stepping used by timing analysis (TRCE and Timing Analyzer)?
Beginning in 4.2i Service Pack 2, the STEPPING level will be included in the TRCE console output:
The STEPPING level can also be viewed in the detailed section of the timing report:
Notice that the STEPPING level in this case is indicated by "MULT_S1", with a corresponding lesser delay parameter for the multiplier.
