Q: Let's consider a snack vending machine which is a mechanical system with a digital control system. This machine can deliver three types of food items, Candy, Chips and Biscuit. The price of the candy is 10 taka, chips is 15 taka and biscuit is 20 taka. The machine is taking money from the customer and then counting it the machine will provide the snack and return no change amount to the customer. The digital control system will be a single IC chip. The machine only accepts 5 taka and 10 takas. So, the valid combinations of the takas are given below: Tk5 Tk 10 Total 0 10 0 10+10 20Tk 5+5 0 10TK 5+5 10 20Tk 10 15TK 5+5+5 0 15TK 5+5+5+5 0 10Tk 20Tk Remember that the vending machine will not return any amount. Now design a snack vending machine which will cover all the requirements using Verilog HDL. Test your design for simulation and also synthesis your design
