I typically use Keil, not IAR. You could review the documentation, or speak to IAR Support staff.
I'd expect you need to check that box, and the one for TIM3, and also write code as you would on real hardware, otherwise there seems little point in having a 'simulator'. The simulator needs to reflect exactly what real hardware would do.
What would work on real hardware
