Currently the standard library includes several components in the microstrip tool box. A tool box is just a directory with the description of models in it.

Remember the arguments are case sensitive, and you can use units.

Properties (TinyCAD only)

These values are translated into the variable block on the text file version of Mason. If you are manually writing the Mason file, you probably want to add these values to the variable block yourself to maintain consistency throughout the design.
