Laboratory Title: Designing Adders and Subtractors
Submittal Date:
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.
Results:
The schematic was created without any difficulty. However, I discovered that the inputs in the
program have to be completely alphabetical/numerical or else there will be errors.
Conclusions:
I was able to create the schematic shown in the lab and simulate the circuit shown with the
Quartus program.
