Vayavya Labs launches OpenHSI™ initiative


Portable Stimulus Working Group


Portable Stimulus Standard 2.0 ready for download

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.



Dealing with Programmable IP: Where the Rubber Meets the PSS Deployment Road


We are conducting a workshop at DVCON 2020 US – Mar 02, 1:45pm – 3:15pm at DoubleTree Hotel, San Jose, CA.

Using Hardware/Software Interface (HSI) based automation in your verification flow offers immediate and substantial benefits. The use of automation cuts downtime in developing device drivers improves quality and promotes reuse of the stimulus model.

This tutorial offers an in-depth view of Hardware/Software Interface (HSI) specification, software stacks, and application to verification of a typical SoC.
