Project Overview
The purpose of this project is to create a counter that starts at 0 and only counts up to 80 and then stops. We also had to wire the board so that when a switch was flipped the counter would reset back to 0.

PLD Circuit |
There are many differences between the Multisim and PLD circuits. The main difference however is that when you construct a circuit on PLD mode, you are then able to transfer the circuit onto a chip where you can then place the chip on the board, and then wire the board to perform the task you created the circuit to complete. You can also assign inputs and outputs in PLD mode which you can link to a leg on the chip.

Conclusion Questions
The difference between SSI (Small Scale Integration) and MSI (Medium Scale Integration) circuits are the number of components and gates. A SSI circuit has less 100 components, or 10 gates, and a MSI circuit has less than 500 components, or more than 10 gates but less than 100 gates. The circuit however was limited to the fact that it had no way to erase human error, for example if someone accidentally pressed the button to reset the counter, it could not change the number back. The ripple effect is the delay it takes for a signal to travel through the circuit in order to change another signal or the outcome. Some of my classmates created their circuits differently by using the single gate for the ones place and the J/K Flip Flops for the tens place.
