Hi, I want to run the example "TimerInt" in the simulator mode, and I should expect printing the value of the VICVectAddr every 1 second in the Terminal I/O window, but it will show nothing.
Does anybody have an idea of what can be?
Thank you
Simulators generally do a very poor job of "simulating" microcontroller peripherals. They also typically run several orders of magnitude slower than the real hardware.
If your unspecified simulator for the unspecified microcontroller (I'd guess LPC2xxx) does a decent job of simulating the unspecified timer at all, one second in its realm may still be 1000 seconds of wall time.

The simulator only simulates an ARM core, not a whole microcontroller. (Hint: no ARM core has VICVectAddr)

Depends on your environment. RealView MDK, for instance, simulates entire MCUs. Even if the OP was using RVISS (formerly known as "Armulator"), there would be some generic peripheral models, mostly based on ARM's PrimeCells. However, RVISS doesn't simulate the PrimeCell VIC, just a very simple non-vectored interrupt controller, based, perhaps, on the ancient APB interrupt controller from the "Reference Peripherals".
BTW: There is a plug-in interface for RVISS that allows people to write their own peripheral models.
