ECET-105 Week 5 Lab: Designing Adders and Subtractors
Objectives: The objectives of this lab was to reinforce the concepts of binary addition and subtraction, to become familiar with the Quartus II program, as well as to build and test a simulation through a simple binary adder/ subtractor.

- Parts List
- Introduction
- Procedure
- Using Quartus II, create the schematic for the circuit shown in Figure 5.3. The schematic must ….. drawn before programming the circuit. Use 74283 for the 4-bit full adder symbol and 7486 for the exclusive-OR gates.
- Compile the circuit shown in Figure 5.3 and correct any errors.
- Perform several calculations to ensure that the circuit is operating properly. Individual values can …. entered by selecting each input and using the mouse to select a specific time period. In the example in Figure 5.4, the grid ….. set to 500 ns to allow multiple different values to be entered. When a time period is selected, a blue box appears. A value of 0 or 1 can …. entered using Set to 0 or Set to 1 buttons.
- Fill out Table 5.1 with your results. The first result is shown in Figure 5.5 (5 + 3 = 8).
