Dual Output Switch in SPICE

[tmoudy]

Hello,
I'm looking to be able to simulate a switch in SPICE where instead of the options being either 'on' or 'off' they are 'on at output 1' or 'on at output 2'.

I was thinking of trying to use two switches with the same input and mirrored controls, but I'm not sure how to do that and in reality that implementation would not be ideal. My other idea was to have a positive and negative controlled switch, but my attempt to implement that just left me confused as to how to make a negative voltage controlled switch (if it is even possible).

Any ideas or help you could give me would be appreciated!

Which version of Spice are you using?

Depending upon the switch model, you may be able to change the parameters of one, so that it is closed with the control input is low and open when the control input goes high.
