IBIS models simulator

icde

Hi everyone, 

I am not sure if my post is in the right place. Anyhow I just downloaded Xilinx and Altera IBIS models. The Altera model is just a word file while Xilinx is a file with an extension .ibs . So is there a specific simulator to run these models or I can use quartus and xilinx simulators to simulate them?
Also can I simulate the model using PSPICE because I tried but didn't know how to import the file to PSPICE and run it ? Should I convert the file first?

Thanks

     You can try importing the IBIS model by running the PSpice Model Editor. Under the Model dropdown menu you will find an "IBIS Translator..." option.

    That is as far as I got, because the IBIS model I got from Fairchild caused the editor to barf due to the IBIS version number.

     Good luck!

    Thanks for ur help.

    The problem im not quite famiier with pspice. so i think im still missing something here. what i did is in the cadance package i have AMS simulator ==> simulation accessories ==> model editor ==> then it gives me the options Design entry or capture (which one??) ==> then do i have to include the library so i can see the option of IBIS translator ?

    Hello,

    I have the same problem as yours. I want to simulate my ibis model in Spectre Cadence. I translated my ibis file to a spice netlist (but I am not sure it is necessary or not !) but I do not know how can I import this netlist or my ibis model in Cadence Spectre for simulation. I use the instance ibis_buffer , but I failed to download my ibis file on it. Could you please help me through this way??

     

    Thanks and regards,

    You need to follow following three steps for simulation of an IBIS model in capture-PSpice
    1. Translate IBIS model in equivalent PSpice model : Open Model Editor > Select Model >IBIS Translator and follow the instruction in GUI
    This will generate <Input File Name>.lib
    2. Generate schematic symbol for this model - Use File >Export Capture part library
    3. Complete schematic with this symbol and associated circuit. Include the simulation model library created at step 1 in simulation profile before performing simulation.

    However you need to make your self familiar with PSpice in order to complete the above steps easily. You may want to refer help > Learning PSpice in OrCAD capture or "Simulating Capture Designs Using PSpice" under Capture user guide for that. Capture user guide can be accessed from Capture >help>Documentation (F1)

    Is there any chance that you can convert the ibis model to mod format for me? I will send you the files. even i am using 16.5 version and need ibis version 3.2. Please help
