Portable Stimulus 1.0 Beta Release Available for Public Review

Recommended Posts

Portable Stimulus

The Accellera Portable Stimulus Working Group (PSWG) is proud to announce the release for Public Review of the latest preliminary version of the Portable Test and Stimulus Standard. This Beta release includes additional work done by the PSWG since the release in June, 2017 of the “Early Adopter” version, reflecting progress on a wide range of issues to improve the standard, including user feedback on the EA version. The PSWG continues to make progress on key features targeted for the 1.0 release of the standard and is committed to ensuring that the standard will open new frontiers of productivity for the industry.

The Portable Test and Stimulus Standard defines a domain-specific language (DSL) and an accompanying semantically-equivalent C++ library to create a single representation of stimulus and test scenarios, usable by a variety of users across different levels of integration under different configurations. It will permit the generation of multiple scenarios from a single specification of test intent, and allow tools to create different implementations of a scenario that run on a variety of execution platforms, including, but not limited to, simulation, emulation, FPGA prototyping, post-silicon and virtual platforms. With this standard, users can specify a set of behaviors once, from which multiple implementations may be derived.
The Portable Test and Stimulus Standard is still a work in progress, which is why we are asking for public feedback. Enhancements to the Beta version being worked on by the PSWG are:

  • Enhanced control of random selection and scheduling of actions
  • Enhanced coverage constructs for coverage of flows, action scheduling, and resource utilization
  • Enhanced features to handle hardware-software interface and product configurable features
  • Enhanced modeling of memory management
  • Enhanced type system to include additional array types and parameterization by type and value
  • Enhanced reactivity of model to environment
  • Enhanced conditional code processing

The Public Review Period will be open until Friday, March 30, 2018. Please provide your feedback via the Accellera Portable Stimulus Forum. All comments will be reviewed by the PSWG. Download the Portable Test and Stimulus Standard Beta release here
