Spice BJT Model Viewer

This app parses a spice bjt transistor model and displays a nice listing readable by humans.

It shows each parameter, one parameter per line, unit measures, parameter modelled and the full standard description of each parameter.

If a parameter is missing, it shows the default value with a grey background.

It checks for duplicates, misspelled parameter names and a bit of syntax.
