SUE options are controlled with the SUE Preferences
(in menu File / Preferences..., "I/O" section, "SUE" tab).
This dialog has two controls:
- "Make 4-port transistors" requests that transistors be 4-port
(with a substrate connection). The default is 3-port.
- "Convert Sue expressions to Electric" requests that SUE expressions be analyzed for parameter
references and converted to Electric parameter form (with an "@" in front of the parameter name).
