Description
Run the current simulation from the current time to the specified time, or until the simulation stops.
A running simulation can be stopped at a predetermined time, at a specific breakpoint in the HDL source code, by encountering a TRUE condition, by evaluating the circuit until there are no remaining events, or by encountering a runtime error such as an out-of-bounds value.
The run
command instructs an existing simulation to run for a specified length of time, or until there are no remaining events. The time is specified as a floating point number indicating a period of time in the current simulation units, or in the specified units.
Arguments
-all
- Run the simulation until no event is left in the event queue, a breakpoint or valid condition is encountered, or a run time exception occurs.
-quiet
- (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config
command.<time> - (Optional) Specifies the length of the simulation run time. The time can be specified as a floating point number, or using the keyword all
.
all
is the same as using the -all
option.<unit> - (Optional) One of the following time units (with or without space between time and unit) can be specified: fs
, ps
, ns
, us
, ms
, or sec
. The default is the value of time_unit
.
Examples
The following example runs an existing simulation for the specified simulation run time, using the default units (ns):
run 1000
The following example runs an existing simulation for 300 microseconds (us):
run 300 us
The following example runs the current simulation until no event is left in the event queue, a breakpoint or valid condition is met, or a simulation runtime error occurs:
run -all
