4 way traffic light verilog code1/14/2024 The module uses an always block to handle state transitions based on the inputs, count, and the presence of emergencies, jams, or empty roads. State: A 3-bit register to hold the current state of the traffic light controller.Ĭount: A 5-bit register used for counting clock cycles to manage signal timings. The module defines several parameters to represent different states, such as green, yellow, etc., for each road. If a bit is set to '1', it means the road is empty (no vehicles present).Įast_road, North_road, West_road, South_road: 3-bit output signals indicating the state of traffic lights for each road. If a bit is set to '1', it represents a jam on the corresponding road (east, north, west, south).Įmpty: A 4-bit input indicating if each road is empty. Jam: A 4-bit input indicating jam conditions for each road. If a bit is set to '1', it represents an emergency on the corresponding road (east, north, west, south). Here's a brief overview of the verilog code:Įmergency: A 4-bit input indicating emergency conditions for each road. The controller uses different states to handle normal operation, emergency conditions, and jam conditions. This traffic light controller controls the signals for four roads: East, North, West, and South. 4-way Traffic Light Controller based on Finite State Machine (FSM) using verilog
