Hi Gurus, I need some information about setting up a source synchronous simulation in spectraquest. 1) The technology that I simulate makes use of Differential strobes. Do I need to set up two strobes in my simulation or a single strobe sampling at both edges. 2) Does the tool sample at both the edges or only at the rising edges. 3)When we make use of Custom measurements, In the IO cell Edit window there is a column for Freq. Does this frequency indicate the sampling frequency ( The rate at which the data is being sampled ). If so what does the Clock freq that appears in the Analysis preferences window indicate. Regards, Rahul. __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!
