The code above was written to answer the question. However, the code only gives the output for S1. Please correct the error in the code. (If necessary, I can send the code, I had to attach pictures of the code because it took up too much space).

Design the given system on Verilog. As per Covid-19 requirements, electronic labs of a well-known university requires a vending machine for dispensing hand sanitizers and masks. Vending Machine only accepts following rupee notes: a. PKR 50 b. PKR 100 Price of each item is as follow: a. Masks - Rs.50 b. Hand Sanitizers Rs. 100 Vending Machine only returns following rupee note: a. PKR 50 If the amount is greater than the item cost, a change will be given back. If the amount is less than the item cost, RED LED has to be switched ON, otherwise OFF. + If the transaction is successful, GREEN LED has to be switched on, otherwise OFF. Make a report which includes the state diagram with proper labelling. Verilog code, Test bench with multiple inputs, simulation waveform and also explain your design.
