Overview of this book

Field Programmable Gate Arrays (FPGAs) have now become a core part of most modern electronic and computer systems. However, to implement your ideas in the real world, you need to get your head around the FPGA architecture, its toolset, and critical design considerations. FPGA Programming for Beginners will help you bring your ideas to life by guiding you through the entire process of programming FPGAs and designing hardware circuits using SystemVerilog. The book will introduce you to the FPGA and Xilinx architectures and show you how to work on your first project, which includes toggling an LED. You’ll then cover SystemVerilog RTL designs and their implementations. Next, you’ll get to grips with using the combinational Boolean logic design and work on several projects, such as creating a calculator and updating it using FPGA resources. Later, the book will take you through the advanced concepts of AXI and show you how to create a keyboard using PS/2. Finally, you’ll be able to consolidate all the projects in the book to create a unified output using a Video Graphics Array (VGA) controller that you’ll design. By the end of this SystemVerilog FPGA book, you’ll have learned how to work with FPGA systems and be able to design hardware circuits and boards using SystemVerilog programming.

Project 9 – creating IPs for Vivado using AXI streaming interfaces

In this project, we are going to take our I2C temperature sensor and split it into IPs that we can use in the IP integrator to reconstruct our project.

Our initial design looked like this:

Figure 7.2 – Original temperature sensor pipeline

Looking at the Xilinx floating-point IP, fix to float, float to fix, add/sub, scaler, and fused multiply/add are all IP blocks with streaming interfaces. What we need to address is the I2C interface that reads the temperature from the ADT7420, the temperature pipeline itself, and the seven-segment display interface. Let's tackle the seven-segment display first.

Seven-segment display streaming interface

The first thing we need to do is create a directory to house our IP sources. This will make packaging easier. We'll do this by creating a directory under CH7/build/IP/seven_segment. Inside this directory, we have an hdl directory...
