Introduction of Design:
Problem Statement: We were tasked with making a circuit using AOI, NAND, NOR, and PLD logic to display our date of birth on a seven-segment display.
Design Process: We were instructed to build our truth tables by finding which components of the seven-segment display are lit up when we enter a certain combination of switches. From the truth table, we built our K-Maps and from the K-Maps we built our Boolean expressions. Using the Boolean expressions, we built our AOI, NAND, NOR circuits. From these combinations, we built it in PLD mode and transferred it into DMS where we tested the switches to display our birthdays.
Parts List:
Conclusion:
My date of birth (5/18/00) was correctly displayed on the PLD and Multisim schematics. This project was difficult because of the small errors that could be made and the challenging task of finding them and fixing them. It was difficult to start the project because I didn’t know how to start it, but after I started, it got easier. I began to learn the logic and how these schematics worked. I spent about 2 weeks on this project and I enjoyed it a little bit. The final result made it all worth it; however, it wasn’t as a fun a soldering.
