PSPICE-FOR-TI: PSPICE for TI: undefinied parameter error using TPS2663

Hi,

Apologies for the delay

I will get back to you by the end of tomorrow.

Hi,

you don't have to change anything to replicate the functionality of TPS26631, existing one in web will work for TPS26631.

I have simulated it; it is working fine.

do one thing delete the existing downloaded pspice , download freshly & then simulate it once it will work, then change circuit according to your specifications.

thanks,

Hi, I’ve just installed PSPICE, so I don’t think reinstalling it will sort it out… it’s the first time I’ve ever used it.

I have removed and reinserted the TPS2663 into the circuit diagram (i.e. without any of my modifications) and the error persists:

I’ve attached the project for you:

TPS2663 NEW_DRIVER.rar

Hi, 

I simulated, I'm facing below two errors, why it would be different for both of us?

ERROR(ORPSIM-15108): Subcircuit CSD19537Q3 used by X_U2 is undefined

ERROR(ORPSIM-15108): Subcircuit BSS145/INF used by X_M1 is undefined

are you using TI pspice ? I'm not facing any issues using TI-pspice with fresh model which exists in website.

thanks,

Hemanth

I’ve reinstalled it, but the error is still there.

I’ll try on another computer, but I’d like you to go into more detail.

I select the component from here, is that right?

Or do I need to download it from here?

Hi, freshly download tps2663 from website, not ti pspice model,

from my end freshly model is working fine, what i would do ?

thanks,

Hemanth

Which of these should I select?

Having followed this tutorial, I don’t have a .lib file, but I do have a .libsig file

Hi,

select OPJ file (project file), just open project file, at very tab of pspice model, file --> open--> project -- it will open project.

thanks,

No, hang on, I’m getting a bit confused.

In the ‘Generate Part’ section, I selected the OBJ file and, in the ‘Destination Part Library’, the OLB file.

So the model was added on the left:

Now?

send me the schematic once

A screenshot of the schematic?

It’s the same as the one I attached earlier; I haven’t changed a thing – I’m just trying to import the component.

1) Is that all right?

2) So what’s the point of creating a project from scratch and then selecting the component from the PSpice part search?

1) correct.

2) you can do that, the project that you have sent i simulated & i told you that the below errors i was getting, these are components added by you & error is  its .LIB or. MODEL file is not included in the simulation profile, so PSpice doesn't know how to simulate it.

ERROR(ORPSIM-15108): Subcircuit CSD19537Q3 used by X_U2 is undefined

ERROR(ORPSIM-15108): Subcircuit BSS145/INF used by X_M1 is undefined
