Project Overview
For this project, we had to construct and build a circuit that would count to 60 and then when it reached 60, reset back to 0 and continue counting up to 60 and again and so on. We also had to have a reset switch built into the circuit that would set the circuit back to 0 no matter what number the timer was set on.
PLD Circuit
This project was similar to the DMV project because we had to wire 2 different circuits onto the board and make them go to 2 different displays. They both also had a reset switch combined inside the circuit. The only difference is that the DMV counted up to 80 and then stopped and had to be manually reset whereas the 60 second timer counted up to 59 and then reset back to 0 and continued to count.
Conclusion
The difference between synchronous and asynchronous circuits is that synchronous counters are each individually wired to the CLK which makes it so there is no ripple effect. Asynchronous counters, however, use the output of the last counter which takes time to deliver the signal causing a delay or the ripple effect.
The major difference between '163 and '193 is that '163 can only count up whereas '193 can only count down. Also, '163 counters will end when the number you want to be displayed is detected for example if you are counting from 2-5 when a 5 is detected the simulation will stop or reset. However with a '193 you must detect the number that follows the number you wish to display for example you would need to detect a 6 in order to display a 5.
The first thing I did in order to complete this project is that I thought about how it would need to be constructed. Then I remembered that the DMV project we just completed used the same layout except the DMV counted from 0-80 and then stopped and the 60 second needed to count to 60 and then reset back at 0 and continue counting to 60. So by using my DMV project and switching around a few wires to detect 59 and then reset at 0 and continue to count I was able to successfully build and wire my 60 second timer.
No, everyone constructed theirs the same way.
