Message from the Chair

Lu Dai, Accellera Systems Initiative Chair2020 has been filled with new challenges brought about by the pandemic, not the least of which has been the need to pivot to virtual events and meetings. We were able to take an in-person DVCon U.S. as COVID-19 began to take hold in the U.S. in March and offer it online to those who were unable to attend due to the rapidly unfolding travel restrictions.

DVCon Europe was held in October on a virtual platform with virtual reality components throughout the two-day conference, providing attendees with a truly immersive, interactive experience. In India, the steering committee was able to organize a virtual Accellera Day India despite the tremendous challenges with the local infrastructure due to the pandemic. Held last week on two half-days, the conference was well attended and received.

In the coming months, DVCon U.S. 2021 will be held entirely on a virtual platform, and DVCon China plans an in-person event on May 26, 2021. The local community will be in attendance, and international participation will be virtual. Stay tuned for more as planning evolves and the new year begins.

Although we have been unable to hold in-person gatherings and meetings, our standards efforts have not languished. Most of our meetings were already held virtually, so progress has continued throughout Accellera’s working groups. Our Portable Stimulus Working Group has made significant advancements toward the Portable Test and Stimulus Standard 2.0 and recently released a draft for public review. This is an important update with great industry support and many vendors offering products based on the standard. We encourage industry feedback on the draft standard through our community forum.

I would like to thank our community for a very productive 2020 despite the unprecedented challenges everyone has faced around the world.

We look forward to a new year, with a post-pandemic optimism and the enhanced remote teamwork capabilities brought about through much creativity and innovation.

From all of us at Accellera, please stay safe and vigilant against the virus. We wish you a wonderful, healthy holiday season and Happy New Year.

Lu Dai, Accellera Systems Initiative Chair


Working Group Update: Portable Stimulus

Portable StimulusThe Portable Stimulus Working Group recently released the Portable Test and Stimulus Draft Standard 2.0 (PSS) for public review. Download the draft standard for review here. The public review is open through December 18, 2020

The draft includes about 90% of the projected functionality that will be included in the official Portable Test and Stimulus Standard 2.0 release expected in March 2021. New major features intend to improve the usability of the Portable Test and Stimulus Standard 2.0 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:

  • Core library for standard portable functionality and utilities for common PSS applications, including register accesses and memory allocation and management
  • Collection types, including arrays, lists, maps, and sets
  • Parameterized types
  • Constraint enhancements, including default constraints and propagation
  • Enhanced activity-level generation and scheduling constructs
  • Improved portability of procedural constructs for test realization

While the working group finalizes the remaining functionality, it encourages feedback from the community during the review period on the major additions included in the draft.

Feedback can be provided through Accellera’s Portable Stimulus 2.0 Public Review Community Forum.

Post-Event Summaries

DVCon Europe 2020

DVCon Europe 2020DVCon Europe 2020 was held in October entirely on a web-based platform, which also included a full Virtual Reality (VR) 3D world. The VR world was used for poster sessions and exhibit booths as well as easy networking among attendees.

The main portion of the conference offered attendees four keynote speakers, 24 technical papers, 13 tutorials, and two panels, all of which were well attended. In parallel with the main portion of the conference there were opportunities for attendees to attend various Virtual Experience Rooms. The rooms contained nine exhibitors and 11 poster presentations and many opportunities to connect with colleagues using an avatar chosen by each attendee.

“Networking is an important component of DVCon Europe, and we are happy with the results of our experiments with the VR world,” stated Joachim Geishauser, chair of the DVCon Europe steering committee. “We felt that this VR experience was very useful.”

The award for Best Paper went to Michele Chilla and Leonardo Gobbi of Qualcomm Ireland, for “Clock Controller Unit Design Metrics: Area, Power, Software flexibility and Congestion Impacts at System Level.”

DVCon Europe 2021 is planned for October 2021 in Munich, Germany.

SystemC Evolution Day 2020

SystemC Evolution Day 2020The fifth annual SystemC Evolution Day followed DVCon Europe as a full-day virtual technical workshop. Focused on the evolution of SystemC standards to advance the SystemC ecosystem, the workshop drew more than 100 attendees from around the world.

There were five interactive technical presentations throughout the day, as well as an update on current activities in the Accellera working groups. Attendees took advantage of the time allotted for open discussion related to the presentations. Virtual networking also provided a great opportunity for colleagues to connect from around the globe to share ideas and experiences.

The morning session contained presentations and discussions about TLM extensions for off-chip protocols, and Multi-core debugger connections, both which generated discussions as well as ideas for future standardization work.

The afternoon session started with Multi-Language Verification, and Temporal Assertions, followed by a presentation on Matchlib, an open source library for HLS. Also here, we had interesting discussions, and topics for further processing in Accellera Working groups were identified.

The presentations are now available for download.

Accellera Day India 2020

Accellera Day India 2020Due to the pandemic, we adapted DVCon India to a virtual Accellera Day India 2020. Held earlier this month over two half days, there were many informative presentations for attendees to choose from. A keynote presentation kicked off each day — one focused on RISC-V and the other on automotive safety. Accellera working group leaders presented updates on Functional Safety and IP Security Assurance, and interactive tutorials focused on formal verification, portable stimulus, USB4 protocol, and UVM methodologies.

“Accellera Day India 2020 is a tremendous success,” stated Sanjay Muchini, Accellera Day India General Chair. “I would like to thank the committee members for their countless hours preparing for the virtual edition with valuable technical content. Our steering committee did an excellent job planning and executing Accellera Day India. With a virtual edition this year, we continue the interest and momentum for our design and verification conferences in India. We look forward to more success with DVCon India 2021.”
