New standard enables users to specify verification intent and behaviors once and use them across multiple implementations and platforms

Accellera Systems Initiative (Accellera), the electronics industry organization focused on the creation and adoption of electronic design automation (EDA) and intellectual property (IP) standards, announced that its Board of Directors has approved Portable Test and Stimulus 1.0 as an Accellera standard. The new standard is available immediately to download for free.

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 behaviors once and observe consistent behavior across multiple implementations.

“This is a significant milestone for Accellera,” stated Lu Dai, Accellera Chair. “Our mission is to provide market-relevant industry standards to help improve and increase productivity. The new Portable Test and Stimulus Standard 1.0 will have a profound impact on the industry as a whole as today’s electronic designs have placed a significant burden on system-level verification methods and have slowed overall designer productivity.

“The Portable Test and Stimulus Standard 1.0 provides tremendous value to the community with increased productivity and quality throughout a product lifecycle,” stated Faris Khundakjie, Chair of the Portable Stimulus Working Group.

DAC Panel
There will be a panel at the 2018 Design Automation Conference in the IP Track, “Portable Stimulus Design & Verification (R)Evolution” on Wednesday, June 27 at 1:30pm in the Moscone Convention Center, Room 2008. Registration is required with the Design Automation Conference to attend.
