Synopsis
This book provides an in-depth overview of on chip instrumentation technologies and various approaches taken in adding instrumentation to System on Chip (ASIC, ASSP, FPGA, etc.) design that are collectively becoming known as Design for Debug (DfD). On chip instruments are hardware based blocks that are added to a design for the specific purpose and improving the visibility of internal or embedded portions of the design (specific instruction flow in a processor, bus transaction in an on chip bus as examples) to improve the analysis or optimization capabilities for a SoC. DfD is the methodology and infrastructure that surrounds the instrumentation. Coverage includes specific design examples and discussion of implementations and DfD tradeoffs in a decision to design or select instrumentation or SoC that include instrumentation. Although the focus will be on hardware implementations, software and tools will be discussed in some detail.
From the Back Cover
On-Chip Instrumentation: Design and Debug for Systems on Chip by: Neal Stollon With each new generation of digital System-on-Chip (SoC) technology, the level of integration, functionality, and complexity provided on a single chip increases significantly and there is a need for better debug solutions. As more processing elements, features and functions are simultaneously being embedded into the silicon, the emerging level of embedded complexity outstrips the capability of standalone Logic analyzer, debugger and emulator based diagnostic tools for embedded designs. This book attempts to fill the need for a comprehensive discussion of on-chip debug instrumentation. It provides an in-depth overview of on chip instrumentation technologies and various approaches taken in adding instrumentation to System on Chip (ASIC, ASSP, FPGA, etc.) design that are collectively becoming known as Design for Debug (DfD). Coverage includes specific design examples and discussion of implementations and DfD tradeoffs in a decision to design or select instrumentation or SoC that include instrumentation. Although the focus is on hardware implementations, software and tools are also discussed in some detail. •Provides readers an invaluable reference on the need, uses, implementations, and systems considerations for adding debug and systems analysis instrumentation to a System on Chip design; •Covers a wide range of techniques, which will be addressed from both an analytic and tradeoff point of view; •Covers both IP and ASP implementations of on chip instrumentation systems, without any bias toward specific products or approaches.
