Accellera Approves Portable Stimulus Standard 3.1: Reusable Constraint Modeling and Heterogeneous Execution Support Added, Available for Immediate Download
Elk Grove, California — Accellera Systems Initiative announced via GlobeNewswire on November 11, 2026 that its Board of Directors has approved the Portable Test and Stimulus Standard (PSS) 3.1, the latest evolution of the industry standard for portable verification intent. The new version is available for immediate download.
Building on the foundation established by PSS 3.0, the 3.1 release advances the vision of enabling engineers to capture verification intent once and reuse that intent across simulation, emulation, FPGA prototyping, post-silicon validation and heterogeneous executing domains. PSS enables engineers to describe stimulus and test scenarios in a high-level, implementation-independent form and automatically realize those scenarios across multiple execution platforms.
PSS 3.1 introduces enhancements that improve model reuse, constraint expressiveness, software integration, target-code generation and coordination across increasingly complex hardware and software execution environments. As set out in the release headline, the new capabilities include reusable constraint modeling, heterogeneous execution support, enhanced software integration and expanded address and register capabilities.
Accellera Systems Initiative is an independent, not-for-profit organization and a force in the creation and adoption of electronic design automation and intellectual property standards for the worldwide electronics industry.
