[Magic-dev] Diodes in Magic

     Magic versions 7.2 and 7.3 support extraction of diodes;  however,
these are very simple and probably need some tweaking in the resulting
SPICE deck if you need a parameterized model.  If you have just one
kind of diode in the layout, you can adjust the model parameters to
match the layout, then it works pretty well.  In the "extract" section
of the technology file, you need:

       device diode <model_name> <p_types> <n_types>

After doing "ext2spice", this will produce the line:

        D<n> <node1> <node2> <model_name>

                                          Regards,
					 Tim
