Frequent questions

  • [FAQ] PSPICE-FOR-TI: My simulation fails to converge and says "INFO(ORPSIM-16594): To improve Pseudotransient Convergence and Performance, set following options: PTRANABSTOL=1e-5, PTRANVNTOL=1e-4"?

    Part Number: PSPICE-FOR-TI Also, How do I add additional options to the simulation profile in PSpice for TI? The following steps may resolve convergence errors if you see the message above: INFO(ORPSIM-16594): To improve Pseudotransient Convergence and…

  • [FAQ] PSPICE-FOR-TI: How do I use my own diode (BJT, MOSFET ...) model for the breakout part in PSpice for TI?

    Part Number: PSPICE-FOR-TI PSpice for TI provides symbols for SPICE primitives such as BJT, MOSFET and DIODE. A generic model is provided but you can modify them to use your own device models. Here is an example. Instantiate the part DbreakZ. It will…

  • [FAQ] PSPICE-FOR-TI: What information is needed for troubleshooting?

    Part Number: PSPICE-FOR-TI When troubleshooting problems with PSpice for TI or TI-developed PSpice models, we may need certain log files. The file locations are often determined by Microsoft Windows environment variables such as "HOME" and "APPDATA"…

  • [FAQ] PSPICE-FOR-TI: I already have the full version of PSpice. Can I still run PSpice for TI?

    Part Number: PSPICE-FOR-TI You can install PSpice for TI and other Cadence Allegro products on the same computer, as long as they are all installed into separate directories. If you have multiple Allegro products, you might have used the switch release…

  • [FAQ] PSPICE-FOR-TI: Using PSpice for TI

    Part Number: PSPICE-FOR-TI This FAQ covers various topics related to obtaining and using PSpice for TI. Licensing Does PSpice for TI need a license to run? I installed PSpice for TI recently and logged in, but received a “license expire” message. What…

  • [FAQ] PSPICE-FOR-TI: Can I define my own model in PSpice for TI?

    Part Number: PSPICE-FOR-TI I use a few MOSFET but there're no models for them. Is there a generic model that I can adjust parameters to fit the datasheet?

  • [FAQ] PSPICE-FOR-TI: I cannot install PSpice for TI. The error message says "An Internal error occurred" (-8) or (-12)

    Part Number: PSPICE-FOR-TI This only applies to error codes -8 or -12 When trying to install PSpice for TI using my access key, I got the following message: What does this mean?

  • [FAQ] PSPICE-FOR-TI: I cannot install PSpice for TI. The error message says "the required files cannot be read from the server".

    Part Number: PSPICE-FOR-TI When trying to install PSpice for TI using my access key, I got the following message:

  • [FAQ] PSPICE-FOR-TI: What do I do if PSpice for TI has crashed or quit unexpectedly?

    Part Number: PSPICE-FOR-TI I was using PSpice for TI and suddenly this message showed up. What should I do?

  • [FAQ] PSPICE-FOR-TI: How do I share PSpice for TI projects?

    Part Number: PSPICE-FOR-TI I want to share my design created in PSpice for TI with my coworker. What're the steps?
