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.
