Thanks a lot.

I connected a discrete space model and a channel implemented by
SimEvent based on the example of 'simple hybrid system' (F-16 model).
But there is always a delay in the SimEvent system. although I set the
sampling period of the two systems to be equal. So I guess matlab
cannot handle two discrete systems. I need to look at my model more
