digital safe lock vhdl code Design Digital Safe Lock - Programmable 4 digit code - Preprogramed master 4 digit code - Red light indicating safe is locked - Green Light indicating safe is unlocked - Option to set alarm after three wrong trials to open it You safe will ship to you with a preprogramed master 4 digit code. You will have the option to enter another/additional 4 digit code of your choice. The safe functions as follows: - You close the safe door and punch in any 4 digit codes and then “lock” button. This will cause the entered 4 digit code to be saved and door to be locked. - To open the safe, either you enter master preprogramed code or the code you entered before hitting the lock button. - Once locked, a red led will turn on to indicate locked status. If unlocked, a green led will turn on to indicate unlocked status. - If wrong code entered three consecutive times then a siren will sound. - Implement a timer to turn off the LEDs after X seconds to save power. To do: - Draw state diagram. Include all design steps and calculations. - Write VHDL program to implement needed circuit behavior. Include detailed comments in your code. - Include different simulation steps to prove different functionality. (more than one simulation) - Explain in details each simulation capture. I cannot grade a simulation that I cannot read or understand. - Write a detailed report including different obstacles you faced and solutions. - Your report should include introduction, design, simulation, conclusion, appendix include properly commented code.
