preference variables and user-defined variables. Note that case is significant in 
variable names.
See Chapter B - ModelSim Variables for a complete listing of ModelSim 
variables.
Variable settings report
The report command (CR-131) returns a list of current settings for either the 
simulator state, or simulator control variables.
Simulation time units
You can specify the time unit for delays in all simulator commands that have time 
arguments:
force clk 1 50 ns, 1 100 ns -repeat 1 us
run 2 ms
Note that all the time units in a VSIM command need not be the same.
Unless you specify otherwise as in the examples above, simulation time is always 
expressed using the resolution units that are specified by the UserTimeUnit 
variable. See the UserTimeUnit 
(B-401).
By default, the specified time units are assumed to be relative to the current time 
unless the value is preceded by the character @, which signifies an absolute time 
specification.
