TL072dual lib

Schematic Simulation (Ngspice)

Hey,
I didn’t found TL072 dual op amp lib on TI website, there is only that:

but 6, 7 and 8 are not mentionned so I can’t get it to work when I do the pin affection.
Any of you have ideas on how to make it work?
I saw people talking about modifying by myself the .lib file. No one did it before?
(same for TL074 if somebody knows)

Add this to the top of the file:

.SUBCKT DUOPAMP 1 2 3 4 5 6 7 8
XUA 3 2 8 4 1 TL072
XUB 5 6 8 4 7 TL072
.ENDS

And then choose the DUOAMP when adding the file.

Thank you !
And for the quad op amp TL074 ?
I don’t understand the logic.

Definitely check out this tutorial for ngspice with KiCad, section 6 includes the same modification that @lucas provided above with more context.

EDIT: forgot the link KiCad Eeschema as GUI for ngspice, tutorial for setting up the simulation

Thank you,
Here’s the link if someone have trouble later:

…oops. Thank you for finding it despite my forgetting the link! I’ll edit my post just for clarity.
