Overview of this book

Modern digital devices used in homes, cars, and wearables contain highly sophisticated computing capabilities composed of embedded systems that generate, receive, and process digital data streams at rates up to multiple gigabits per second. This book will show you how to use Field Programmable Gate Arrays (FPGAs) and high-speed digital circuit design to create your own cutting-edge digital systems. Architecting High-Performance Embedded Systems takes you through the fundamental concepts of embedded systems, including real-time operation and the Internet of Things (IoT), and the architecture and capabilities of the latest generation of FPGAs. Using powerful free tools for FPGA design and electronic circuit design, you’ll learn how to design, build, test, and debug high-performance FPGA-based IoT devices. The book will also help you get up to speed with embedded system design, circuit design, hardware construction, firmware development, and debugging to produce a high-performance embedded device – a network-based digital oscilloscope. You’ll explore techniques such as designing four-layer printed circuit boards with high-speed differential signal pairs and assembling the board using surface-mount components. By the end of the book, you’ll have a solid understanding of the concepts underlying embedded systems and FPGAs and will be able to design and construct your own sophisticated digital devices.

Ensuring comprehensive test coverage

To ensure that nothing of critical importance is overlooked when designing a suite of tests for your system, it is necessary to approach the design of the tests in a methodical manner. The use of appropriate metrics will tell you how well your tests cover the aspects of the system that require testing.

One important metric is the degree to which the test process assesses system performance against each requirement. Another metric, focused on the software and firmware portions of a system design, evaluates the degree to which the test suite covers the various flows of execution through the code. The next section addresses the coverage of system requirements during testing.

Requirements traceability matrix

A requirements traceability matrix (RTM) is a table that documents the test cases that address each system requirement. By developing an RTM during the test design process, you can determine which of the requirements have been validated...
