Hi i am in a bit of a bother.I just found out about simulink last month.While trying to simulate Thz cmos circuit I encountered several problems.
Problem 1:why does red dots appear instead of black wires while connecting two devices.
Problem 2:how do I simulate a rectifier.At first they want me to use powergui block and then a solver block yet i cannot simulate.

Anyone who wants to help me out please see the link below.Its pretty simple,yet I guess I am making some sort of error.
