Hello fine humans!
First of all, thank you kindly for creating kicad; it is an amazing tool! I am however, having great difficulty with the simulator; may I please have some baby-step assistance.
ngspice: hopefully ~30+???
I am trying to simulate a non-inverting opamp, however, I need to use the opamp model below from ti.com.
Problem = cannot get externally imported sub-circuit models working; .lib files in particular from ti.com.
What I have already done:
I have both the .spiceinit & spice.rc files with “set ngbehavior=ps”. I have both of these files located in my “Home” directory as depicted in the file explorer GUI. I have downloaded and unzipped the model of interest into the folder of my kicad project. I find the .lib file using “edit spice model”, and change the “alternate pin numbering” accordingly. I do not have a “.include” text sting on my schematic with the path to the file.
different kicad outputs:
- Too many parameters for subcircuit type “ths3001” (instance: xxu1)
- I was able to probe/view the input to the opamp, however, the output was constant at some arbitrary value since kicad could not resolve the model.
I have confused myself, and I am out of optimism; seeking professional help. This is my first question via online forums, so please be gentle; I’m aware that my post is lacking information.
Thank you in advance peeps!
