SUE (Schematic User Environment) is the database format of the SUE schematic editor, from Micro Magic (www.micromagic.com). For more information on reading SUE, see Section 3-9-2.

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).
