Demo and Student Projects for Fall 2023 CSE 30342 Digital Integrated Circuits at the University of Notre Dame

This project is based on the examples in section 2.4.5 of Digital Electronics 3: Finite-state Machines, and the FSM state machine example from Chapter 5 Section 5 of Figure 5.5 of The Zen of Exotic Computing [2][1]. There are two modules to the design: the controller and the counter. The counter has the inputs of EN =1, clk, clr (clear) with the outputs of rcoL (long count), rcos (short count). The counter-output values are fed into S and L controller inputs, respectively. Then, the controller has the remaining R, C, and clk inputs, with IC, NR, NG, NY, ER, EG, and EY outputs. The outputs of the N value represent the state of the traffic light facing north-south streets, while the output of the values starting with E represents the state of the traffic light facing east and west. By default, the North/South street is green, while the East/West street is red. Changes in state color are determined by the value of C "detecting" a car present on the East-West street(s).

This chip models the behavior of a traffic light in a four-way intersection.
