For a design that has a lot of I/O events, a simulator has to be very, very carefully scripted, if it is possible at all, to create the randomness and nesting as will be seen in the real, "noisy" world of interrupts.

You can also manipulate the irq load and other environment things there for worst case situations to get an error free application. To do this in real hardware is not a easy thing. If you add monitoring code to your software the timing relevant things will be totally differnt and maybe your application works only with debug code but you will maybe have problems if you run your "relaese" version.
