Overview of Debug Standardization Activities

The semiconductor industry is disaggregated, with a complex web of suppliers and consumers. Standards help to facilitate and simplify the debug process. This article provides an overview of current standardization activity. One area in need of such standardization is that of on-chip debug processes and instruments. The debug area particularly exhibits limited commonality between different IP providers in terms of interfaces and methods for complex SoCs. The problem becomes even greater with more SoC integrators using diverse IP from different vendors, requiring an increasing range of debug, analysis, and optimization capabilities. This article describes the goals and ongoing activities of five debug standardization bodies: the Nexus 5001, MIPI (Mobile Industry Processor Interface) Test and Debug, IEEE PI149.7, IEEE P1687, and OCP-IP (Open Core Protocol International Partnership) Debug working groups.
