theoretically if you use printf statements you should see the output in the Simulation console. You should be able to see this even if you run your simulation in Optimized or Development mode. The simulation Debugger can provide you more information on actually happens during the simulation (only in Development mode). But if you are interested only in the output of the printf statement you can look in the Simulation Console.

use the following command to print statements to standard output

op_prg_text_output("%s","Your Text");

I know the command but what is the standard out put?how i could see the standard output?

Simulation Debugger

As Flavius said, you can see them in the simulation console if you are running a simulation in development mode. But, there is another way to do that.

In the preference file (Ctrl+Alt + P), find the "Console". Then you can see the "Show Console Window". Set it as "True".

Close modeler and run it again. Then you can see the console window. Then the output of print will be shown in that windows irrespective of simulation mode.
