Dear all;
I think tutor's hyperlynx version (v8 i guess) had some issues with built in models(or may be in simulation engine ,who knows) :In module 2 , tutor shows drive strength and toggles between Slow-Weak ,Typical and Fast-Strong IC modeling options. But when he run simulations, Rising edge stabilizes on 5V at 9ns for all 3 cases. But it has to be differ. I think this is corrected in v9.
I decided tol follow remainig modules using virtual lab but do not bother signal shapes and timing anymore.
