The Portable Test and Stimulus Standard (PSS) defines a specification to create a single representation of stimulus and test scenarios usable by a variety of users across many levels of integration under different configurations. This representation facilitates the generation of diverse implementations of a scenario that run on a variety of execution platforms, including, but not necessarily limited to, simulation, emulation, FPGA prototyping, and post-silicon. With this standard, users can specify a set of behaviours once and observe consistent behaviour across multiple implementations.

Vayavya Labs has played a key role in the development of this standard, in particular on the HSI/test realization constructs.
