Using Sweeps with Additional Parameter option in Transient Simulation

mcunning

Expanding on the answer given here, is it possible to use a paramset sweep in a paramset.scs file during a transient? 

I have a 5-bit switched attenuator that I would like to simulate switching during a transient. Without typing all 32 states in a single paramset statement, I would like to know if a paramset could be swept between values at specific time increments.

e.g. I would like to increase from a 00000 to 11111 (represented using five variables: c4,c3,c2,c1,c0) in steps of one bit every time  seconds.

The progression would be similar to the following:

time =    0ns > {c4,c3,c2,c1,c0} = {0,0,0,0,0}

time =  50ns > {c4,c3,c2,c1,c0} = {0,0,0,0,1}

time =100ns > {c4,c3,c2,c1,c0} = {0,0,0,1,0}

time =150ns > {c4,c3,c2,c1,c0} = {0,0,0,1,1}, .... etc.

Not sure it's possible, but I appreciate any input.

Thanks,

Michael

    I got the impression that it wasn't possible, but thank you for confirming. In hindsight, listing out all the steps explicitly wasn't all that bad (especially if you only need to do it a few times).

    Thanks again, Andrew.
