8.47 Write VHDL code that can be used to synthesize the circuit specified in problem 8.46. 8.46 Design a circuit for control of lights used to start a race, which works as follows. There are three inputs: Reset, Start and Clock. There are three outputs: Red, Yellow and Green, which turn on the lights. Only one light can be on at any time. The Reset signal forces the circuit into a state in which the red light is turned on. When the Start signal is activated, the red light stays on for at least one second longer, then the yellow light is turned on. The REFERENCES 581 yellow light stays turned on about one second and then the green light is turned on. The green light stays on for at least three seconds and then the red light is turned on and the circuit returns to its reset state
