ARM: CORTEX-M3 DEVICE SIMULATION RESULT DIFFERS FROM REAL HARDWARE
Information in this article applies to:
While toggling an I/O pin on a Cortex-M3 device, I noticed that the target hardware executes slower than simulation.
Why is the timing different?
The Cortex-M3 simulation is cycle accurate with the following exceptions:
In general, this means that the simulator will execute a bit faster than hardware.
Simulation will differ slightly from the hardware regarding cycles due to:
