Linear SwitchCAD III: How to adjust voltage of digital components?

[Al Borowski]

Hi all,

I'm simulating a dead simple oscillator, consisting of an inverting
schmitt trigger, a resistor and a capacitor. It works fine expect the
output of the schmitt trigger is 1V when high. I'd like to set this to
3V (I'm trying to simulate a circuit running off 2 AA batteries).

I'm using version 2.14 of SwitcherCAD III.

I'd appreciate it if someone could point me in the right direction.

thanks,

Al

Control right click on the schmitt trigger symbol, double click on the
blank space to the right of 'spice line', and type in 'vhigh=3'. You can
also set 'vlow', and various other parameters. Check the help in the
appendix.

Thanks a ton! Now I know the keyword, I found the help easily enough.
