TINA/Spice/AM26LV32E: AM26LV32E

Part Number: AM26LV32E
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

So I'm having a bit of trouble getting this IBIS model up and running in PSpice. I'm Using OrCad Capture.

Here is what I've done so far:

1. Open Model Editor

2. File > New

3. Model >IBIS Translator

4. Browse and select "am26lv32e.ibs" file. Note that as soon as I select it, the below files and folder are created:

am26lv32e.dml

am26lv32e.lib

am26lv32e_ibis2pspice.log

devices.dml

temp.lisp

signoise.run(Folder)

5. With Select ALL, Typ, and Use 2 V-t Tables selected I hit OK

6. 4 items appear in the Models List, 2 for the differential inputs, one labeled input that I assume is for the enable, and one labeled output.

7. Click File > ....

8. "Export to Part Library" is greyed out

Everything I've seen online uses "Export to Part Library" and I haven't found much for an alternative. If you have one that'd be great. If you know how to fix the model editor to work that would also be great. In every example I've seen in using "IBIS Translator" there was only one item in the Model List so I am not sure if there may be something special about this part or if perhaps I am improperly using Model Editor.

I opened Model Editor just by clicking "Edit PSpice Model" on another part then hitting "File > New" to clear out that parts IBIS info. I don't know if that would effect it but I'm used to being able to find Model Editor within the Cadence dropdown but the version my work owns seems to have things moved around a bit.

    Hi Eric,

    Try the following, it should work for you:
    1. Open Model Editor
    2. File -> Open -> am26lv32e.lib
    3. Export Part to library.

    Hey Herman,

    I actually solved getting the export part to library about an hour after I posted this. Turns out you can't open model editor from within capture and expect it to work. To anyone with a similar problem where your work hides all the .exe files and just gives you a shortcut, right click the shortcut and chase down where the actual start file is in properties. The model editor .exe is in the same folder.

    I am having another problem with this model now however.

    The model has 4 parts. A positive input by itself, a negative input by itself, a "typ" input by itself, then a part with one input, one output, and an enable. I can't figure how I am supposed to use these together since they don't seem to interact with each other. The part with the output seems to use it's input as single ended as far as I can tell which doesn't do much for simulating a differential receiver.

    Hi Eric,

    The IBIS model is not intended to do the interaction like what you have described. It has something to do with the nature of IBIS model.So when you export it into Pspice, then the same limitation applies.
