General System Requirements: A digital controller is required to control a traffic light at an intersection of a busy main street and a side street. There are vehicle sensors on the two side street lanes to sense presence of vehicles. Pedestrian crossing buttons are present for crossing the main street only. Use you KSU ID to set the intervals for the lights: The 2nd highest numeral in your KSU ID set the main street green time, The 2nd lowest numeral in your KSU ID set the side street green time. The yellow time is to be 4 seconds. Example: KSU ID 000123456 The main street is to have green light for a minimum of 5 seconds or as long as there is no vehicle on the side street. The side street is to have a green light for a maximum of 2 seconds. Use the following notation: Input Signals VE = Side Street Vehicle Sensor Pa= Pedestrian Button = Long Timer for Main Street Ts = Short Timer for Side Street Ty = Yellow Timer Output Signals MR = Main Street Red Light My = Main Street Yellow Light Mg = Main Street Green Light SR = Side Street Red Light S = Side Street Yellow Light SG = Side Street Green Light State Machine Signals So = LSB Si= MSB Project Grading: Block Diagrams State Diagram State Table VHDL w/waveforms Block Diagrams Details: Combinational Logic Sequential Logic Timing Logic General System Requirements: A digital controller is required to control a traffic light at an intersection of a busy main street and a side street.
