Hi!

I'm pretty new to LT Spice, and I would like to modify the parameters of an inverter gate. I found the following website below, which describes what should be done to be able to change certain parameters, but I have no idea how to implement it.

This is the directive that I tried to change the logic high level to 10 volts, but it did not work:
.param a1 n001 n002 n003 n004 n005 n006 n007 n008 buf Vhigh=10

 

Right-click on the inverter symbol and in the pop-up enter 'Vhigh=10' as the Value.

Thanks a lot for the quick help, it works!

 

Good. LTS has a steep learning curve (I'm only part way up it myself) but is well worth the effort.
