Simulation control tasks allow you to stop or quit simulation.
$stop [(n)] ;
$finish [(n)] ;
The $stop system task is used to suspend simulation. When invoked it suspends simulation, prints simulation time and prints location. Optional expressions can determine the type of printed message:
|
Expression (n) |
Message |
|
0 |
No message |
|
1 |
Simulation time and location |
|
2 |
Simulation time, location, memory consumption and CPU time used in simulation |
By default the value 1 is used.
The $finish system task ends the simulation, exits the simulator and passes control back to the operating system. It can be invoked with the same arguments as the $stop system task and has the same default value.
Example 1
$stop ;
Suspend simulation and print message (default argument = 1)
Example 2
#150 $finish(2) ;
Exits simulator after 150 time units from the last executed statement and prints message (argument == 2).
Remember that $finish control system task makes the simulator exit, however $stop simply suspends simulation.
