ModelSim variables

Several variables are available to control simulation, provide simulator state feedback, or modify the appearance of the ModelSim GUI. To take effect, some variables, such as environment variables, must be set prior to simulation.

ModelSim variables can be referenced in simulator commands by preceding the name of the variable with the dollar sign ($) character. ModelSim uses global Tcl variables for simulator state variables, simulator control variables, simulator preference variables and user-defined variables. Note that case is significant in variable names.

See Appendix A - ModelSim Variables in the User's Manual for a complete listing of ModelSim variables.

Variable settings report

The report command returns a list of current settings for either the simulator state, or simulator control variables.
