Question about simulation

Hi everyone, i've a question for you.
I've created a project with EDK 9.1 with a custom ip ; when i send some bits to my custom peripheral, it should create a waveform based on the sequence of the bits i've send. I've simulated the edk project with modelsim and everything seems to work but if i download it to my board and try to see the waveform with an oscilloscope connected to a fpga pin, i don't have the the same result i've obtain with simulator, but it's very different.
Is it possible that there's so much difference between simulation and execution of the program (i thought that simulations were reliable) or maybe i've made errors during microblaze configuration?
