Design a countdown timer in Verilog to show the count down from an initial value set by the two push buttons on the prototype FPGA board. For the design, - Use two push buttons to set the time in minutes and seconds (like MMSS). - Use the third push button to start the countdown. When the count reaches zero, turn on a LED. Display the time in decimal on four 7-segment displays (2 for minutes and 2 for the seconds like MMSS).
