Hi all, I am using the B element of HSPICE ( as recommended by the gurus) to simulate my IBIS model that I created. This IBIS model is for TTL I/Os that I created using the s2ibis utility. The complete model looks fine but when I simulate one of the macro models I see a digital signal rather than an analog signal that I should see at the output. When I take the hspice deck for the TTL I/O and simulate it I see a nice analog signal at the end. This, I believe but the B element simulation of the IBIS model I do not believe. Basically this is what it looks like: --------------- * * * ----------------- for the hspice output and -------------- * * * ------------------------ for the IBIS output. What could I be doing wrong here? Any inputs will be appreciated.
