TINA/Spice: Importing .mod to Tina9-TI

Carlos,

Your specific question is actually quite easy to answer. LT does not normally provide a PSpice compatible model that can be imported into any other simulation tool. They only provide models built into their simulator LTSpice. The .asc format is an LTSpice specific format which contains the schematic and all associated models and statements as a self contained file (equivalent to the TINA-TI .TSC file). It can ONLY be used in LTSpice. You may also contact LT to see if they will provide a PSpice model for the IC you are interested in using.

TINA-TI can import any PSpice compatible models into the tool using the New Macro Wizard which is detailed in the TINA-TI video series

Video 1.9 shows how to import devices into TINA-TI. There is also a very good document on importing models into TINA-TI which does have step by step information about the import feature and how to tell if the netlist is compatible with TINA-TI.

I hope this information helps.

The models I want to use from LTSpice are not for LT products. They are parts that simply do not exist in Tina's library.

And I thought there might be a simple way to convert the components text files in TINA models, but there is not. I watched video 1.9, and you practically have to design a new part from scratch. Not too practical. I thought the txt file was common to all Spice models.

Carlos,

Can you share the model text file?

Carlos,

Apologies for assuming that you were looking for LT devices. If you can provide me one of the .txt files (or .mod files), I can walk you through the process step by step. It really is quite easy and similar to the way you would import a file into any of the simulators available.

Let me know how I can help.
