Please be aware that most of the models available here are intended to be used as hierarchical subcircuits. The details of these sub- circuits do not appear as cryptic text files, but rather in the instantly available, graphical form of familiar LTspice schematics. This puts the display of internal waveforms just an easy point-and- click away. Since LTspice will look in the directory of the top level schematic for any hierarchical symbols and schematic blocks used, these elements must be copied to the same directory as the top level schematic that uses them to be recognized. For further information on using LTspice's powerful hierarchical schematic drafting capability refer to the Help file topic, "Schematic Capture => Hierarchy".
