Texas Instruments Spice model files TI Spice models are provided in the ".zip" compressed format. Each .zip file contains the following files: (1) readme.txt (this file) (2) ths____.lib: a library file that should be loaded into the PSpice simulation profile, under the "library" tab. (3) ths____.olb: graphic library used by the Cadence Capture program. This library consists of a single part, or multiple parts if more than one device is present per package. This library should be added using the "add library" function under "place parts". When the library is added, the symbol(s) within the library should be visible. (4) ths____.txt: A generic Spice library file to be used in Spice model programs other than PSpice and Electronics Workbench. TI supports PSpice with the necessary files (see below), and provides Electronics Workbench with models which load in their product. Depending on the part, there may be multiple instances of .lib, and .olb files. Line driver products containing both a driver and receiver, for example, require different models for the driver and receiver section of the IC.
