IR2101 Gate Driver with IRF3205 MOSFET Simulation KiCAD Crash Problem

ahmedyar · July 2, 2023, 10:18am

Hello Everyone,

Its been Six months I’ve been using this wonderful tool … KiCAD.
Thanks to the team here at this forum, For starting, I got a lot of help from here. I’ve tried making simple circuits and simulating them in KiCAD.

I am currently stuck in simulating a circuit where IR2101 is driving MOSFETs (IRF3205).
I got device models from the manufacturer product page(IR2101.lib, irf3205.spi, and 1N4148.lib).

The issue I am facing here as soon as IR2101 is included in the simulation (Compatibility mode: PSpice), KiCAD crashes otherwise out of many combination (I’ve tried during two days effort to run the circuit), simulation either goes on or atleast talks to me (such as “step size too small”). However, as soon as i include IR2101 in the simulation, KiCAD crashes away (perhaps gets angry at me for some obvious mistake).

I am using KiCAD Ver. 7.0.5 on Windows 10, and including the *.lib/.spi models as “SPICE models from file”

I tried to attach the KiCAD project, but I think new users can’t upload attachments.
I shall be thankful for the rescue.

Regarding being a new user, check out New Member Information for instructions on upgrading yourself to be able to upload project files.

Regarding crash, I’m just guessing that there is something wrong with the specific model you have so ngspice is crashing and bringing down KiCad with it. If that guess is correct, the relevant bug report is tracked here (though unfortunately no timeline for fixing the issue is given yet): Spice simulator cause Kicad to crash if netlist includes a spice library with syntax errors (#14568) · Issues · KiCad / KiCad Source Code / kicad · GitLab

Or an ‘assist’ from a mod. User now equal basic.

ahmedyar · July 2, 2023, 6:11pm

Thanks for a detailed response, based on that information I am uploading the schematic image (may be it can provide some insight for the mistake I am making).

I tried IR2104, its library provided by the Infineon … same situation.

scone · July 2, 2023, 6:13pm

If the crash is occurring as soon as you load the model into KiCad (selecting it in a symbol’s SPICE model editor) then the issue is unlikely to be the schematic, but the model file itself. Can you upload the entire project directory, including models? Alternatively, posting a link to the exact model you are working with could also be helpful.

ahmedyar · July 2, 2023, 6:17pm

This is link to the model I am using:

Can I share the whole project folder using google drive?

scone · July 2, 2023, 6:21pm

You can do Google Drive if that’s fastest for you, but generally speaking it is nicer to upload .zip files of the project directly so that it is easy to reference later (link rot and all that). If you want to open a gitlab issue (or add to the existing one) in the future, you’d definitely need to upload a zipped project.

ahmedyar · July 2, 2023, 6:24pm

Many thanks, in parallel I am exploring gitlab.
Perhaps, since I am not much expert at KiCAD … i think most probably some mistake by me is causing the trouble.

Project Files (RAR)

scone · July 2, 2023, 6:43pm

For whatever it is worth, .rar is not a cross platform compression system so many people will not be able to open the file as provided. Most OS’s other than Windows default to .zip rather than .rar for compression. There are certainly workarounds (on Mac there is a common utility called The Unarchiver) but I figured I’d let you know.

Anyways, I was able to open your schematic file without any issues and re-attach the IR1201 models without any issue. I noticed you’ve excluded the IR1201’s from simulation, presumably to keep it from crashing? I unchecked that setting on the top IR1201, no crash yet. I opened the simulator window, transient model with default settings, and set compatability to PSPICE. Running the simulation does result in an error message.

Just for fun, I switched compatibility mode to PSICE and LTSPICE, hit OK, and immediately got a crash. This is reproducible with just the LTSPICE compatibility mode as well.

All of this to say there are two or three issues here (from my point of view):
The IR1201 model is not fully compatible with ngspice (the underlying spice library) even with the PSPICE compatibility mode. Something about it is Really broken when you throw LTSPICE compatibility mode into the mix, even though they should be able to operate together (“LTPSA should be the standard” from PSPICE simulation fails permanently (#13589) · Issues · KiCad / KiCad Source Code / kicad · GitLab ).
Then there’s the KiCad level issue of crashing when ngspice does, which may be covered by the pair of these issues: Spice simulator cause Kicad to crash if netlist includes a spice library with syntax errors (#14568) · Issues · KiCad / KiCad Source Code / kicad · GitLab and Crashing simulation (ngspice) should not crash kicad / eeschema (#9756) · Issues · KiCad / KiCad Source Code / kicad · GitLab.

ahmedyar · July 2, 2023, 7:01pm

Thanks for the suggestion regarding file type, yes that is so. I shall try to follow it in future.
Other than that, your response is a priceless rescue … spent many hours on it, in the clouds of uncertainity … taking it as my own mistake in making schematics.

Meanwhile, I am getting into gitlab.

scone · July 2, 2023, 7:07pm

I’m glad I was able to help! I’m unfortunately not good enough at SPICE to know why the IR1201 model is causing an error in PSPICE mode and causing a crash in LTSPICE mode, but I’d encourage you to create a new issue on the KiCad Gitlab and potentially generate a reproducible case for ngspice alone (though the lead dev on ngspice often pays attention to the KiCad gitlab as well).

ahmedyar · July 2, 2023, 7:12pm

But your help enabled me to direction my effort,
I came across a discussion at sourceforge, there is some deep rooted (I am in learning mode) issue with infineos SPICE models at NGSPICE.

sourceforge discussion
Sourceforge link to the patched model of IR2101 (compatible with ngspice)

Schematic is not yet working, require further workout … but with this patched model atleast KiCAD does not head to a crash.

Jeffbeck · July 2, 2023, 8:10pm

There is here : Simulation examples for KiCad/Eeschema/ngspice - #4 by holger
A file using a similar driver. Try using that one.

holger · July 2, 2023, 9:57pm

Even with an incompatible model ngspice should not crash.

I will prepare a fix to ngspice.

nestor_espinoza · June 27, 2024, 9:39pm

Buenas, estuve leyendo tus comentarios. Te quería preguntar si esta disponible la lib del IR2101 para LTSpice. La estuve buscando sin poder tener éxito. Gracias

Mod edit:
Hello, I was reading your comments. I wanted to ask you if the IR2101 lib for LTSpice is available. I was looking for it without being able to succeed. Thank you
