Hello Dave,

Thanks for your interest and reaching out to our team on E2E! Please take a look at this post, [FAQ] How Can I Simulate TPSI305x-Q1 Using Pspice for TI, and let me know if you have further questions.

Hello Dave,

I tried simulating with your settings but was unable to recreate the issue. I did a quick search and this seems like a PSpice For TI issue rather than an issue with our TPSI305x-Q1 model. Looks like if you select a different directory during installation rather than the default directory, this results in some sort of permissions issue that generates the error message you are seeing. 

1. Try navigating to "devparam.txt" in your install directory and Add as Global. Then try simulating again. For me, it is under "C:\Cadence\PSpiceTI\tools\pspice\library"
   
   
2. If "devparam.txt" is not there, copy this attached .txt file to the folder, add to global in library path, and try simulating again.
   

   * This is the PSpice device and its parameters mapping file
   *
   * File Format of devParam.txt
   * 	Fields are separated by a space or tab. 
   *
   * For Each record:
   *	There are four fields on the line: <DeviceType> <noNamedParam>* NAMEDPARAMS: <namedParams>* 
   *   Where:
   * 	<DeviceType> is a device-type character.
   * 	<noNamedParam>* is a list of no-named parameters.
   *   NAMEDPARAMS: is a key word.
   * 	<namedParams>* is a list of named parameters.
