TINA/Spice/LOG101: How to import spice model to Orcad Capture? Or any way to using this spice model with my own schematics?

Part Number: LOG101
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hello, I am very happy to learn about TI E2E community.

I am writing this question to ask how I could import LOG101 spice model into Orcad Capture.

I have been trying to manipulate three files (mod, sch. slb) given by TI, but I always see the blank page in LOG101 slb file.

In addition, when I open LOG101.sch file, I always encounter the error saying that 

Local library 'C:\SPICE\Burr Brn\LOG102\LOG102.slb' not found for 'C:\Users\(MY_DIRECTORY)\LOG101.sch'

Local library 'C:\SPICE\Burr Brn\LOG102\LOG101.slb' not found for 'C:\Users\(MY_DIRECTORY)\LOG101.sch'

Basically, it seems that LOG101.sch file does not find itself LOG101.slb files, as there is no part symbol.

Is there any way I can do to resolve this problem? My original goal was to import this file into ORCAD Capture and integrate LOG 101 chip on my circuits.

Is there any lib. file supported for LOG101 users?

Thank you very much for your help in advance,

Jae

    Jaehoon,

    This is a very old model and not in the latest format that we release. However, you should still be able to use it.

    (1) Rename the .MOD file to .LIB. This is the model file.

    (2) Create a new project in Orcad (as you would normally do irrespective of whose model you are using).

    (3) Open a empty schematic and create a new simulation profile. In the profile, associate this .LIB file from step (1).

    (4) Create a symbol for this model using the Symbol Editor. This should create an .OLB File

    (5) Add the OLB file to your project and instantiate the symbol from the OLB file on your schematic. 

    (6) Build your circuit around this model and simulate it.

    Dear Nikhil,

    Hello Nikhil,

    Thank you very much for your reply. This has helped me figure out what I should look for.

    Unfortunately, I could not resolve this problem, so I would like to ask for your further help.

    1) I renamed LOG101.MOD into LOG101.LIB

    2) I opened PSPICE MODEL EDITOR, and I used "Create Capture Parts" which converts LIB file to OLB file.

    3) I added this OLB library in Capture, and I manually added LOG101.LIB file on Libary of Design Resources and Model Libaries of PSPICE Resources.

    I added this library when I was on Libarary tab of Simulation Setting.

    But, I got the error saying Subcircuit LOG101 used by X_U2 is undefined.

    Would this be the problem gained from compatibility? Or is there anything I have missed?

    Thank you very much for your help in adnvace,

    Sincerely,

    Jaehoon

    I checked the MOD file and the model is present. Did you create a "Simulation Profile" and add the LIB file to it? That is how the simulator knows where to look for the model. From your message it seems like you have not done this and hence the simulator is not able to find the model.
