Lab #6: Hardware Implementation of a 4-Bit Calculator Using Full-Adder Chips In this lab you will build the hardware of a 4-bit Adder-Subtractor using the Full-Adder and XOR chips. This lab is to be done individually . Part 1: Building the Full-Adder Subtractor in SimUAid For this part of the lab, you will build in SimUAid your Full adder subtractor from Lab 4 part 2. This will be the same circuit build as that from Lab #5, only that you will be working with only the full adder and XOR chip. Shown below, Figure 1, is the least significant bit of your circuit build: Figure 1: The LSB Full-Adder Subtractor Cell Note: For Questions 1 and 2 on the next page, use the same values as those from Lab #4.
Questions: 1. Give four examples of A + B using your calculator . (Hint have A>0 + B>0, A>0 + B<0, A<0 + B>0, and A<0 + B<0) Make sure you place them in a table in your lab report, and add screenshots of your build from SimUAid. 2. Give four examples of A - B using your calculator . (Hint have A>0 - B>0, A>0 - B<0, A<0 - B>0, and A<0 - B<0) Make sure you place them in a table in your lab report, and add screenshots of your build from SimUAid.
Part 2: Building your SimUAid Design in Hardware For this next part of the lab, you will build your circuit design using your breadboard. Make sure that your circuit can perform addition and subtraction. Remember that binary subtraction can be done using 2’s complement binary arithmetic. For your hardware build, you are allowed to only use the Full-Adder and XOR chip to complete your circuit. Make sure that your demo is no greater than 5 minutes in length. In your presentation, perform 4 addition and subtraction operations fro m the previous part’s Question 1 and Question 2, respectively. Use LED s as indicators for your calculator. Note in the video which is the MSB and the LSB LEDs. Demo notes: It is required that your video is continuous, i.e. there should be no pauses, edits or interrupts to the recording. The demo must show you DISASSEMBLING your circuit in your video at the end of the demo. Failure to do so will result in a loss of 50% of your grade. The demo must be no more than a 6-minute video. Add it to your Google Drive and put a link to that video in your report.
