What’s inside the recent Accellera standard for portable test and stimulus.
The definition of the language syntax, C++ library API, and accompanying semantics for the specification of verification intent and behaviors reusable across multiple target platforms and allowing for the automation of test generation is provided. This standard provides a declarative environment designed for abstract behavioral description using actions, their inputs, outputs, and resource dependencies, and their composition into use cases including data and control flows. These use cases capture verification intent that can be analyzed to produce a wide range of possible legal scenarios for multiple execution platforms. It also includes a preliminary mechanism to capture the programmer’s view of a peripheral device, independent of the underlying platform, further enhancing portability.
