This contrasts with manual design which involves reduction a computer-aided design (CAD) program prescribes efficient, low-cost hardware for such designs as a digital traffic-light controller. Karnaugh maps, and in which both design time and the probability of error increase rapidly with the number of input and feedback lines. In the CAD program, written for sequential circuits, use of clocked D-type flip-flops for the memory greatly simplifies the design of the combinational, or gate, part of the network. Input data are derived from a state table. Use of the program to design a digital controller for a city traffic light at the intersection of a main thoroughfare, and a side street is described in detail.
