Project 2 – Creating combinational logic
In this chapter, we’ve discussed signal types and how to create combinational logic. This project will contain multiple components that allow us to come up with a small calculator. It will be a rather simple one and will have the following capabilities:
- Find the leading-one position of a vector’s input via switches
- Add, subtract, or multiply two numbers
- Count the number of switches that have been set
The following diagram shows what the Nexys A7 board looks like:

In the previous chapter’s project, we learned how to use switches for input and LEDs for output. In this project, we’ll be using all the switches in the preceding diagram for the number of ones calculator where we will produce a binary count from 0-16 based on the number of switches that are on. Additionally, we’ll create an LOD where we’ll detect the position...
