This appendix documents the following types of ModelSim variables:
• environment variables
Variables referenced and set according to operating system conventions.
Environment variables prepare the ModelSim environment prior to simulation.
• ModelSim preference variables
Variables used to control compiler or simulator functions (usually in .tcl files)
and modify the appearance of the ModelSim GUI (usually in INI and MPF
files).
• simulator state variables
Variables that provide feedback on the state of the current simulation.
