HI,

I have tried to run the pspice transient model on orcad 16.6.However when i simulate the circuit it give me this error.

Is there anything run with how I run it or is it the model's problem? If it is the model's problem , what should I do to fix the error. Thanks for your help

I just want to note that I also tried the tps61045-trsn.DSN file and the model insider still provide me with the same error.

    Fred,

    I just pulled down the PSpice model from the web and did not have any issues running the design. Is it possible that the .lib file you pulled down got corrupted? Please pull down the .zip file from the product folder and try that .lib file again. If the problem persists, please let us know and we will investigte it further.

    I have tried to pull down the zip file again and I run the .opj file inside the folder with orcad 16.6 and it still give me the same error. Do i need to do anything special to run the simulation. I only run the product installation when installing orcad 16.6. Do i need to install something else? Also, when the first time I want to save the tps61045-trans.opj, it willl pop up a message saying the database is created in the older version and they will update to a newer version. Would that cause the problem? Here is some message I got when I first run the simulation

    INFO(ORPSIM-15423): Unable to find index file tps61045_trans.ind for library file tps61045_trans.lib.

    INFO(ORPSIM-15422): Making new index file tps61045_trans.ind for library file tps61045_trans.lib.

     I also found the same issue with TPS61040. However, I can successfully run the model for TPS73101. Is there any difference between importing these two models into my orcad 16.6?

    Thanks for you help.

    Fred,

    The .ind file is an index file that is created everytime you start a new design. We remove it so that PSpice will re-create it when you open the design/project. You will not get that information if you run the design again. That is not causing the problem.

    The reference designs we put on the web are created using version 16.2. We do this so customers using version 15.7 or higher can open the design. Projects/designs created by version 16.3 or higher cannot be opened with older versions.

    Is it possible that you have a permissions issue on the file? Plase make sure that you have read/write access on all of the .lib files and the directories underneath the design. I will ask another engineer here to open the .zip files in 16.6 to see if the same problem occurs. If it does, I will let you know.

    Hi,

    Yes I do have access to write and read  to the lib file. It just takes awhile to load from one sub circuit to the other. I am assuming all the code is ecrypted because I cant really see the code. All I can see is the following:

    ----------------------------------------------------------------------------------------------------------------------------------------------------

    $CDNENCFINISH
    .ends TPS61045_TRANS_S14

    ----------------------------------------------------------------------------------------------------------------------------------------------------------

    Just to provide you with more info. When I check the subcircuit there is nothing name $ as well. I am not exactly sure why the simulation will read $.One last thing is that even though I cant run TPS61045 and TPS61040, I can run TPS61041. Hope this information will help you to figure out the problem. Thanks
