VSIM Tcl commands
These additional VSIM commands enhance the interface between Tcl and
ModelSim, Only brief descriptions are provided here; for more information and
command syntax see the "ModelSim Commands"
(CR-11).
ModelSim Tcl time commands
ModelSim Tcl time commands make simulator-time-based values available for
use within other Tcl procedures.
Time values may optionally contain a units specifier where the intervening space
is also optional. If the space is present, the value must be quoted (e.g. 10ns,
"10 ns"). Time values without units are taken to be in the UserTimeScale. Return
values are always in the current Time Scale Units. All time values are converted
to a 64-bit integer value in the current Time Scale. This means that values smaller
than the current Time Scale will be truncated to 0.
