A very short falling edge pulse will be generated in the test_out output port during rtl simulation in modelsim ase 6.5b. However, I cannot see this short pulse in Quartus II simulator during functio...

Honored ContributorIt looks like a glitch, that is most likely ignored in functional simulation. You should try timing simulation to see, if it's actually there. It may be a case of different results between simulation and synthesis, however. If the signal is sourced from combinational logic, it must be generally expected to have glitches, when more than one input terms are changing simultaneously.
