problems with pspice model when simulating with spectre

Two things:

1. Please give the link where you downloaded the models from - I found these models for the first device at https://www.infineon.com/cms/en/product/power/mosfet/silicon-carbide/discretes/imw120r020m1h/?tab=~%27simulation_models#!designsupport but it does say that these models are for SIMetrixTM-Spice and there's no reference of Pspice.
2. Please also provide a netlist that shows the problem - knowing how you are instantiating the device and simulating it - how the models are included, the analysis statements etc is pretty important to understand what's going on.

Even then, this may be beyond what I can do in the forums - it may need more detailed investigation (the models are pretty complex) - so I may end up advising you to contact customer support. You might want to do that anyway instead!

Hello  Andrew

I mistook the spice model provided by infenion as the pspice model，This may be the reason why I encountered those problems.

This is the way I used to call the spice model of Infinion：creat a new cellview---Select pspice in the type column in the 'new file' interface ---Copy spice model code to the text editor（pspice）PSPICE-editor editing  interface---creat---cellview from cellview ---select schematicSymbol in the Tool/Data type column .  After the symbol of the device is generated, it is directly called in the way of ‘creat instance ’ in the Virtuoso Analog Design  Environment L Editing  interface.The following is a schematic I built for testing.

Qunshan,

Investigating this wasn't helped by you only having included a screenshot (or rather two screenshots) of the netlist rather than providing it as text. Luckily I could copy and paste the text (by OCR of the images) and then fix a few mistakes where 1's got identified as l's and so on. I was also assuming that you were including the model from Infineon-CoolSiC_silicon_carbide_MOSFET_1200V-SimulationModels-v01_00-EN/Infineon-CoolSiC_silicon_carbide_MOSFET_1200V_SPICE-SimulationModels-v01_03-EN/IMW-IMZA120RXXXM1H_7-40mOhm.lib .

I don't have your models for mn20v and mp20v, so I just made some simple models up, and with that the simulation runs without any issues in the current Spectre version 21.1.0.716.isr18 . Which Spectre sub-version are you using? (this should show at the top of the log file).

Andrew

Hello  Andrew

I'm sorry to show  the netlist in the way of screenshot, I will pay attention next time.

I have included the the model of IMW120R020M1H in the netlist ,Just like the last line of netlist：

pspice_include "/home/qsliang/SiC/SiC_model/IMW120R020M1H_L3/pspice/design.pspice"

The design.pspice file only contains the code related to the IMW120R020MH model, which was copied from the IMW-IMZA120RXXXM1H_7-40mOhm.lib  file, as follows：

The version of spectre is 15.1.0.257 64bit

Do I need to install a new version of spectre ?

Yes. You are using the base release of spectre (then called MMSIM as the release stream) from October 2015 - so almost 8 years ago. Why use something so old? We have a major release of Spectre almost every year (not in 2022, but in every other year).

Running some tests, I see the messages in the version you're using, but not from Spectre 16.1.0.240.isr2 onwards (SPECTRE161) - released in February 2017. So this has not been an issue for more than 6 years.

The current version is SPECTRE211 - subversion 21.1.0.716.isr18

By the way, I edited your post as you had posted Infineon's copyrighted material - since I'd already posted a link to it, I removed it from your post.
