How to change logic levels in LTSPice?

Hello Joerg,

I highly recommend to use a web browser. There are so many goodies on the group's webpage. You would miss them all if you use any simple message viewer. After you have registered the for the group, set your email account to "No email". Otherwise your email account would be flooded with 500 messages per month.

First time for me to do mixed mode sims on LTSpice. How do you change the voltage level of behavioral logic such as "AND" from the default 1V to some other voltage?

Maybe even other parameter such as rise/fall times, prop delays?

Hello Joerg,

Right-mouse-click on the device in your schematic. A dialog will be shown. Enter the parameter(s) into any field from "Value" to "SpiceLine2".

Vhigh=5 Vlow=0 Ref=1.5 Trise=5n Tfall=5n Td=5n

"Ref" is the threshold. Default is (Vhigh+Vlow)/2

Don't connect anything to unused inputs!

You want or need examples?

Thanks, Helmut. I just got mail from a reader of these groups and he suggested the same. Works!

That's what I tried at first. Well, at least no smoke came out of the PC. In real life it would have been phssst ... BANG :-)

I'll have to see whether I can get that group through gmane. The Yahoo interface is such a pain.

Well, I am signed up since a while. Another ID and password to remember, sometimes it won't recognize me, and so on. If at least the message board itself would be a newsgroup. So much more efficient.

Just like all other private Yahoo groups. You need a Yahoo e-mail address, and to request to join the group. No big deal, if the moderators are on the ball.
