NI Zhen-cheng · 2002
If a ring counter does not start on itself, choose an input port of a Flip-Flop, as correct port, in Karnaugh map, modify the constraint term out of the original logical simplified loop into 1, the constraint item must be border upon logic with the efficient state term 1 in the original logical simplified loop, then it can be modified it into a self-starting logical circuit.
