Code needed in Verilog
Objective Your objective in this lab is to design (code, simulate and implement) a parking meter much like the ones around It should be able to simulate coins being added and show the appropriate time remaining. Also, it should flash slowly when less than 200 seconds are remaining and flash quickly when time has expired Description You will design a finite state machine that will simulate the operation of a traffic meter. The buttons on the board will represent different coin denominations and the seven segment LED display will output the total amount of seconds remaining before the meter expires. Button 0 Button 1 Button 2 Button 3 Switch 0 Switch 1 Configuration 1 Add 30 seconds Add 120 seconds Add 180 seconds Add 300 seconds Reset time to 15 seconds Reset time to 185 seconds As soon as a button is pushed, the time should be added immediately. When less than 180 seconds remain, the display should flash with period 2 seconds and duty cycle 50% (on for 1 sec and off for 1 sec; so you will see alternate counts on the display eg- 185,blank,183,blank,181...). When time has expired, the display should flash with period 1 sec and duty cycle 50% (on for 0.5 sec and off for 0.5 sec). For example, when the board starts, it should be in the 0 time remaining state and be flashing 0000 at a 0.5 second rate. If button 3 is then pushed, the display should read 300 seconds and begin counting down. When the time counts down to 200 seconds and button 2 is pushed, the display should then read 380 seconds (200 180). If switch 0 goes high, then the time should change to 15 seconds and flash accordingly Button 0 Button 1 Button 2 Button 3 Switch 0 Switch 1 Add 50 seconds Add 150 seconds Add 200 seconds Add 500 seconds Reset time to 10 seconds Reset time to 205 seconds Objective Your objective in this lab is to design (code, simulate and implement) a parking meter much like the ones around It should be able to simulate coins being added and show the appropriate time remaining.
