CMOS Inverter VTC and Transient Simulation Tutorial Using Xschem and Ngspice

[@graybeardmicrowave3074]

Thank you. I was able to get the SKY130 PDK going with this demonstration.

Thank you for showing me how to connect two nets electrically without routing a wire to it. I am working on a huge project with >30 transistors. Thanks a lot. ♥ from india

Is there a way to sweep the simulation over all corners? I've managed to get the temperature and voltage variation simulated but I'm not sure at how to get all corners shown in a combined analysis

Whenever I click on waves after simulation, my gaw viewer opens up but no graph is displayed on the screen. What to do?

[@aswincvenu3958]

I also have that annoying scheme bug, do you have a an AMD graphics card?
Xscheme uses an old graphics library which is causing this bug.

What is the command to measure rise time and fall time?

Hi, thanks for the controbution, where is the model files tt, sf, ss ???

@bminch, Wave option is not working, it showing that gaw : not found, but i am installing gaw, no package avaliable showing.
so please help

@@bminch i installed this but i found that no mmodel file (tt, sf, ss etc) other thing find but not this . so withut this simulation will run or not.
you can also check on git hub that on tt, sf files.

@@abhishekvarshney7008 I'm having same issue, unable to add different models (tt, ff etc)
Have you got solution?

@@parasgidd7830 you can find them in xschem home page copy the file and paste it in your design file
