Ok, but how do you connect a digitial simulator whit an analog one (I am
new to this field, so be patient): the timestep control of the analog section
can interefere with the digital part: I mean how we can avoid to loose a
state change in a digital signal because the timestep is too large ?
There should be surely a solution to this problem, otherwise mixed mode
simulation will be not very useful.

Can you give some good refrence on the subject ?
