The Tcl time command displays the current simulation time scaled to the specified unit. The unit can be
- A time unit that you specify
auto: use the largest base unit that makes the numeric part of the time an integer
module: use the timescale of the current debug scope
The simulation time can be displayed in the following time units:
fs: femtoseconds
ps: picoseconds
ns: nanoseconds
us: microseconds
ms: milliseconds
sec: secondsmin: minuteshr: hours
If no unit is given, the value of the $display_unit variable is used. This variable is set to auto by default.

time Command Options
This section describes the options that you can use with the Tcl time command.

Includes the delta cycle count. The At any given simulation time, values of nets are first updated and then behaviors that are sensitive to those nets are executed. This two step process may be repeated any number of times because of zero-delays. The delta cycle count represents the number of times the process is repeated for the given simulation time. |

Does not include the time unit. |
