Otherwise LTspice looks first in the directory \lib\cmp and then \lib\sub and then in the directory that contains the calling netlist, where is the directory containing the bltadwin.ru executable, typically installed as C:\Program Files\LTC\ LTspiceIV. To add an intrinsic component, a ‘.model’ file needs to be saved in the LTC\LTspiceIV\lib\sub directory and for an extrinsic component, a ‘.subckt’ file needs to be added. Steps to include new device/ component models into an LT Spice schematic: METHOD 1: 1) Firstly, one needs to download the required device model having bltadwin.ru extension. · I'm trying to add bltadwin.ru to my LTspice in mac os x so I can analyze a nmos circuit. (I figured it's relevant to this thread and I'm not trying to hijack it) We've been given the attached file, but I'm not sure I can use it because it's for hspice in windows.
And this is the place where you find out and/or tell LTSpice about such things. Once bltadwin.ru file was in place, the next thing to do is to download the datasheet and get it up and visible, as well. Now I have bltadwin.ru file visible AND ALSO the datasheet visible. And I know that LTSpice can find bltadwin.ru file, as well. Good. Fairchild supplies bltadwin.ru file, bltadwin.ru, for this IGBT (ON Semiconductor has acquired Fairchild). This file, as are all SPICE input files, is an ASCII text file. Although in LTspice, the file extension is arbitrary, Fairchild has chosen to use bltadwin.ru extension for its SPICE models and subcircuits. Fairchild has. A Spice model file is nothing more than a text file with a different extension. In the case of LTspice, if the model file contains only a single model, it should be named with bltadwin.ru extension. If the file contains multiple models, then the file should be named with bltadwin.ru extension.
