Problem Statement Design a circuit that increments a digit (0-F) shown on the seven-segment display device once each second. The circuit has four pushbutton inputs: one button starts the counter, a second button stops the counter, a third button increments the counter, and the fourth button asynchronously resets all memory devices in the design. The system has the block diagram shown Fig. 1 below. You must create the 4-bit counter, a clock divider, a seven-segment display decoder, and a controller circuit. You may use any design tools or methods you wish. You must also create and submit a state diagram for the controller, together with K-maps showing the next-state and output circuits in your final report.
