vending machine using Verilog
Hi welcome to qyestverse Verilog code for vending machine: `timescale 1ns / 1ps module vending_machine ( input clk,reset,select_item, input [1:0] coin, // Input coin: 2'b01 for 1 unit, 2'b10 for 2 units output reg dispense, output reg [3:0] change ); parameter IDLE = 3'b000, ONE_UNIT = 3'b001, TWO_UNITS = 3'b010, ITEM_READY = 3'b011, DISPENSE = 3'b100; reg [2:0] current_state, next_state; reg [3:0] amount; // Tracks the inserted amount always @(posedge clk or posedge reset) begin if (reset) begin current_state <= IDLE; ...
