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 ModelSim 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 UserTimeUnit.

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.
