Graph constructs for timed execution (graph.wait(N), graph.resume() and graph.end(N)) behave differently in the AI Engine simulator and the x86 simulator. For the AI Engine simulator N specifies the processor cycle timeout, whereas for the x86 simulator it specifies a wall clock timeout in milliseconds. Thus, if your test bench uses timed execution the AI Engine simulator and x86 simulator might produce different results, in particular, the amount of output data produced might differ.
