I have found a PSPICE model for a part I'm interested in.

ISL55110 Datasheet: https://www.mouser.com/datasheet/2/698/isl55110-11-1302115.pdf

Manufacturer PSPICE Model: https://www.renesas.com/cn/zh/www/software/simulation/isl55110_spice_model.txt?key=7c34d7bf3964f39e34346fc510d75e83

In the past, when I needed to use manufacturer models of components in PSPICE, I would simply find a part that was already defined and had the same number of pins/parameters and copy-paste the code into the spice model editor.

For example:

Vishay - BZT03C200 PSPICE model copy-pasted into D1N4467 from the DIODE library.

enter image description here

enter image description here

Which gives me the desired result.

I've looked through all the gate drivers in the MFET_DRVR library, but there are no components that have the number of pins shown in the above datasheet, which is 9.

How can I go about using this model in PSPICE? I have looked into how to make custom components with specific numbers of pins/parameters/etc., but I was unsuccessful in making one work. Also, doing a google search has come up with a few forum posts, but many of them are amibiguous to me since I am unfamiliar in using Cadence.

  • \$\begingroup\$ Is one of the 9 pins the Silicon Substrate? \$\endgroup\$ Commented Nov 22, 2018 at 19:54
  • \$\begingroup\$ The pins are: VDD, ENABLE, PD, IN-A, IN-B, OB, GND, VH, OA. It comes in a package with 16 pins, but the rest are NC. \$\endgroup\$

1 Answer 1


I was able to find documentation from another manufacturer that helped.



They were slightly dated, and there was still an issue after execution, with the simulation saying that one of the internal nodes 'X_U1' was undefined.

Then I found this post: 'Missing subcircuit' when creating a Pspice library part from the OPA188 Spice file provided by TI

Which detailed how to remedy this problem, and everything worked perfectly!
