How do I import the simulation models from a vendor?

[lunix]

I downloaded the spice models from Mouser, but the extensions do not mean anything (and don’t agree with KiCad’s simulator extensions. If I knew how to rename (which one to rename with which extensions)- I could probably make these work. The extensions are these: *.5_1 ; *.5_2 ; *.101 ; and *.102

Then there’s tlc272readme.txt which contains:

tlc272.5_1	(5V)Dual, General Purpose, CMOS - Level 1 Model	1	TLC272 Operational Amplifier Macromodel Subcircuit
tlc272.101	(10V)Dual, General Purpose, CMOS - Level 1 Model	1	TLC272 Operational Amplifier Macromodel Subcircuit
tlc272.5_2	(5V)Dual, General Purpose, CMOS - Level 2 Model	2	TLC272 Operational Amplifier Macromodel Subcircuit
tlc272.102	(10V)Dual, General Purpose, CMOS - Level 2 Model	2	TLC272 Operational Amplifier Macromodel Subcircuit

Would someone who knows please point me in the right direction? (I think the model might’ve been made by TI, if that helps).

Perhaps you should go to ti.com instead? No one knows where Mouser got their models from, Mouser’s a broker/dealer, not a manufacturer.

I was hoping for some info on how to do this task in KiCAD. I’ve been an EE for 40 years (retired now), so I’ve dealt with Mouser and most of the major distis and most of the major semiconductor companies. But not with KiCAD.

Hasn’t anyone else using KiCAD downloaded non-trivial spice models from Mouser?

Here’s the ti.com model:
TLC272 data sheet, product information and support | TI.com

Extract the one you need and save it in the directory of your project.
Rename it with a .lib extension.
Open your schematic and select the TLC272 part using right-click (or the menu). Select Properties.
Click Simulation Model and add the .lib file

This is very helpful. And I did it (renamed the “5_1” extension, then tried the “5_2” extension). Each sort-of works apparently when I import, but I get an error when I try to simulate the circuit:

[Window Title]
Error

[Main Instruction]
Errors during netlist generation.

[Content]
Error loading simulation model: no ‘Sim.Name’ field
No simulation model definition found for symbol ‘U1’.

[OK]

You definitely got me started, but I am stuck again. Sorry, and many thanks for your help. I would love to get more of it!

There is a tutoral available at KiCad Eeschema as GUI for ngspice, tutorial for setting up the simulation.

You also may have a look at my videio channel, especially at https://www.youtube.com/watch?v=Wg7uSs4J_0U.

Thanks very much for your help- ML9104, holger!!! It works now. I have to figure some more stuff out with simulation. If I can’t- I will come back. But I think you got me over the “hump”.

Thanks again!
