arduino emulator on pc/mac

Hi, Are there any arduino simulator for mac/pc? I've already tried Simulator for arduino for pc and I don't like it (there are a lot of ads).

Thanks

Thomas

The best simulator for the Arduino is an Arduino. What are you looking for a simulator to do, and why isn't using the real thing a better alternative?

because i'm waiting for my first arduino (it is in shipping) and i want to test my programs for arduino.
