Accellera Systems Initiative has posted for public review a draft of version 2.0 of the Portable Test and Stimulus Standard (PSS).
According to Accellera, the draft includes about 90% of the projected functionality that will be included in the official PSS 2.0 release scheduled for publication in March 2021. The group has published the current draft to obtain feedback from the community on the major additions included in the draft while the group finalizes the remaining functionality. The public-review process will close on December 18, 2020.
The main aim of the features is to improve the usability of portable stimulus as defined in the standard and expand its portability and flexibility to a broader class of verification challenges. Additions to the draft of the 2.0 standard include several new language features. There is a core library for common PSS applications, including register accesses and memory allocation and management. There are several standard collection types, including arrays, lists, maps, and sets. A further addition lies in constraint enhancements, including default constraints and propagation. There are also enhanced activity-level generation and scheduling constructs.
