Project 1 – 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 learn 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 and the leading-one detector. For the leading-one detector, we'll detect the position of the left-most switch that's been set out of the 16 positions.
For the...
