How to use the new Portable Test and Stimulus Standard in practical applications.

10.1Unleashing Portable Stimulus Productivity with a PSS Reuse Strategy
The emerging Accellera Portable Test and Stimulus Standard (PSS) promises to boost verification reuse by allowing a single description of test intent to be reused across IP block, subsystem, and SoC verification environments, and provides powerful language features to address verification needs across the verification levels and address the specific requirement of verification reuse. However, language features on their own do not guarantee productive reuse of test intent. This paper describes methodology and a planning process to minimize duplicated effort and maximize the reuse benefits of adopting the emerging Accellera Portable Test and Stimulus Standard.

10.2Results Checking Strategies with Portable Stimulus
The paper will explore how to apply the Accellera Portable Test and Stimulus Standard to architect a results checking strategy that will work at all levels of abstraction, focusing on reusing verification intent, rather than verification IP, across multiple platforms. We will include an explanation of modeling the critical aspects of results checking in an abstract model, and discuss how users can tailor their PSS models to provide flexibility for tools to generate efficient tests at different stages throughout the block-to-system verification flow. We will also share results from users who have employed these techniques on actual projects.

10.3Product Life Cycle of Interconnect Bus: A Portable Stimulus Methodology for Performance Modeling, Design Verification, and Post-Silicon Validation
Portable Stimulus Standard (PSS) is the latest industry standard created to allow the specification of test intent and behavior such that the test stimulus can be re-used across various target platforms. The introduction of PSS alters the traditional approach of verifying and validating a SoC, offering many advantages and a few challenges. This paper explores these process changes with the life cycle of an Interconnect Bus Fabric from System-C based Performance Analysis to verification and validation using a Generic PSS based Traffic Generator.

10.4Test-driving PSS for System Low-power Validation
This paper describes the application of the new Portable Stimulus Standard (PSS) to post-silicon validation, focusing on exercising power behaviors of the system, hardware and firmware, in different usage profiles. The solution pattern we describe is simple but quite general. We share lessons learned with respect to the PSS language and its expressive power for specifying tests in this domain. We also have encouraging proof points concerning the level of automation and reuse that can be achieved by a tool processing these descriptions. We believe our experience with PSS contains valuable observations for validation teams and the standard committee alike.
