Selecting a Portable Stimulus Application Focal Point

As designs, especially SoC designs, have become more complex, the need for generated good automated stimulus across the verification spectrum has increased. Today, the need for verification reuse and automated stimulus is clearly seen from block to subsystem to SoC-level verification. This article explains how portable stimulus helps to improve SoC designs. Read More Find [...]

Create more flexible virtual sequences with Portable Stimulus

Everyone who has used UVM has used sequences to generate stimulus. Simple sequences drive single interfaces using transactions. Virtual sequences control more complex behaviour, such as driving multiple interfaces or running a series of lower-level sequences to implement a higher-level test.This article explains how to create flexible virtual sequences with portable stimulus. Read More Find [...]

Portable Stimulus: Finding the Killer App

The verification intent model defines paths through a design. This is a complete departure from existing verification methodologies that split stimulus generation, from checking, and from coverage. The verification intent model captures the fundamental actions that a design is supposed to be able to perform, and how to achieve the results. This article explains how [...]

Building a Better Virtual Sequence with Portable Stimulus

When using the UVM, sequences are the primary mechanism by which stimulus is generated in the testbench.Portable stimulus can create virtual sequences easier, increase the verification value achieved by running these virtual sequences, and enable more reuse of the description used to create the virtual sequence. This article shows how portable stimulus applies to creating [...]

Total Value of a Portable Stimulus Standard

The creation of the portable stimulus standard has raised several issues about the trade-offs between using an industry standard language and a domain-specific language. This article from Eda Café describes how the inclusion of C++ option provide you with a more powerful solution that fits your needs both today and in the future and that [...]

The Making of a Standard

The industry waits with bated breath for the Accellera board to approve the Portable Stimulus 1.0 specification. It has been a long and arduous process over the past four years to get to this point, a process that most people never get to experience. This article focuses on some of the difficulties associated with bringing [...]

Portable stimulus smooths path to SW-driven verification, eliminates duplication

Taking a step-wise approach to verifying interactions between embedded processors and the IPs in the rest of the design saves time by finding bugs earlier in the verification process when they’re easiest to debug and correct.Portable stimulus allows high-quality tests to be generated from test intent that is described once and retargeted to multiple environments.This [...]

Choosing a Format for the Portable Stimulus Specification

From the early days of the Accellera Portable Standards Working Group (PSWG), it was apparent that trying to satisfy a wide range of users with a single input format would be difficult. Hardware designers and block-level verification teams are used toconcepts such as constraints and biasing whilst most validation engineers using hardware platforms mainly write [...]

System Functionality Includes Software

While a lot of information is produced to introduce and support individual verification techniques, methods for applying a variety of verification techniques in a complementary way are harder to come by. This article from EDA Café explores what was happening with portable stimulus and what new techniques we would have to learn and explains where [...]
