I have downloaded and unzipped an encrypted mosfet library from Fairchild (ONSemi). The file is called ONSemi_SUPERFET2_600V_LTspice.zip. This library is specifically meant to be used with LTSpice. The zip file contains device schematic symbol files (xxxxx.asy, where xxxxx is the device name), one file for each device in the lib, as well as a text file named ONSemi_SUPERFET2_600V_ltspice.txt. This txt file is, presumably, the encrypted *.lib file containing the spice parameters of the devices.
Below is a cut and paste of the start of this text file:
The Hex code at the bottom of the screen dump above, continues for the remainder of the file.
I copied the unzipped directory containing the *.asy & *.txt files into the LTSpice\lib\cmp directory and then attempted running a simple simulation using one of these mosfets. LTSpice produced an unknown subcircuit error. Here is a screen dump of the circuit schematic and the error message:
What do I need to do in order to successfully run the simulation ? Many thanks in advance!
