This book describes an approach and supporting infrastructure to
facilitate debugging the silicon implementation of a System-on-Chip
(SOC), allowing its associated product to be introduced into the market
more quickly. Readers learn step-by-step the key requirements for
debugging a modern, silicon SOC implementation, nine factors that
complicate this debugging task, and a new debug approach that addresses
these requirements and complicating factors. The authors' novel
communication-centric, scan-based, abstraction-based, run/stop-based
(CSAR) debug approach is discussed in detail, showing how it helps to
meet debug requirements and address the nine, previously identified
factors that complicate debugging silicon implementations of SOCs. The
authors also derive the debug infrastructure requirements to support
debugging of a silicon implementation of an SOC with their CSAR debug
approach. This debug infrastructure consists of a generic on-chip debug
architecture, a configurable automated design-for-debug flow to be used
during the design of an SOC, and customizable off-chip debugger
software. Coverage includes an evaluation of the efficiency and
effectiveness of the CSAR approach and its supporting infrastructure,
using six industrial SOCs and an illustrative, example SOC model. The
authors also quantify the hardware cost and design effort to support
their approach.
