How to stop the verilog Simulator?

[priya]

Hi ,

I am writing simple verilog code.The verilog code will get the input
value from Some mechnical devices.assuming that the Verilog simulator
is faster than mechnical devices.So the Verilog Simulator will need to
wait some specified time until the mechnaical devices reaches that
specified time.and also it should not run other process in the same
code.Need to stop all other process in same code .If there is any way
to do it using icarus verilog simulator?
is there any syntax to do it the above things?
