Suresh, You didn't say whether you wanted to drive the bit stream to the other lines with a current or a voltage source. I assume a current drive is required, and suggest an ICIS (current controlled current source.) That is in their manual as an F element, and also in Tuinenga's book on SPICE.

I have the sum of three PWL current sources beng injected into one line. I want to inject the inverse of this bistream in the adjacent trace to simulate worst case cross talk. Does anyone know of an simple cosntruct in Hspice to achieve this? Thanks Suresh __________________________________________________ Do You Yahoo!? Yahoo!
