Si2 Announces Winners of Inaugural Power of Partnerships Awards

Engineers from Intel, Samsung and Synopsys Honored

AUSTIN, Texas – Semiconductor design experts from Intel, Samsung and Synopsys are winners of the first annual Si2 Power of Partnerships award which recognizes the Si2 group or committee that has made the most significant contributions to the success of electronic design automation industry.

Volunteers of the Si2 OpenAccess oaScript Working Group were the winners of a competition between committees from each of three Si2 coalitions:  OpenAccess, Compact Model, and OpenStandards.  Key contributors from the oaScript Working Group will be recognized during the Si2 Annual Member Meeting Reception at the Design Automation Conference in Las Vegas, Monday, June 3, 4:00 – 5:30 p.m. Las Vegas Westgate Hotel, Ballroom F.

Honorees from the oaScript Working Group are:

  • Rudy Albachten, oaScript Working Group Chair; Co-Chair, OpenAccess Coalition; and Principal Member of the Technical Staff, Intel
  • James D. Masters, Engineering Manager, Intel
  • Cory Krug, Senior Staff Engineer, Samsung
  • Christian Delbaere, Senior Staff Research and Development Engineer, Synopsys

Marshall Tiner, Si2 director of Production Standards, said the oaScript Working Group plays a major role in expanding the functionality of OpenAccess, the world’s most widely used standard API and reference database for integrated circuit design. “This group has brought EDA development capabilities directly to the designers. EDA startups and design groups within end-user companies use it for rapid development of production design tools that strengthen OpenAccess’ relevance,” Tiner said.

“The use of scripting languages, such as Python, to directly access the OpenAccess database is a powerful feature. Turn-around time for creating and modifying scripted code is very fast, and almost all new university graduates are well-versed in one or more scripting languages. Beyond this, there are a number of additional packages available, such as the powerful Polygon Operators extension which relies on oaScript. Access to AI tools, such as TensorFlow, which is built on Python, is now accessible to our users,” Tiner added.

Each Si2 coalition nominated one team for the inaugural award, which spotlights the essential role that teams and individual member volunteers play in Si2’s continuing success:

Runners up in 2019 were:

Compact Model Coalition:  Gallium Nitride High Electron Mobility Transistor (HEMT) Model Working Group, which released two standard models in 2018, culminating a multi-year effort by members and developers.

OpenStandards Coalition:  Unified Power Model Working Group developed several versions of a specification for system-level power modeling focused on IP blocks of arbitrary complexity.

James Masters of Intel to Lead Si2 Extensions Steering Group

AUSTIN, Texas — James Masters of Intel has been elected chairman of the Silicon Integration Initiative Extensions Steering Group, a team of industry volunteers that creates productivity enhancements to OpenAccess, the world’s most widely used standard API and reference database for integrated circuit design. Si2 is a leading research and development joint venture that provides standard interoperability solutions for integrated circuit design tools.

The ESG was launched in 2011 to increase the ease and pace of adding OpenAccess functionality, through extensions to the database, without affecting the consistency and stability of the core API standard and its associated reference implementation.

Marshall Tiner, Si2 director of Production Standards, said the ESG is responsible for reviewing and approving new features and capabilities for the API which are not part of the regular development process. “This has allowed for more flexible development in the OpenAccess environment to meet ever-changing market requirements,” Tiner said.

“James has played a major role in the ESG since its creation. His work with Si2 is an example of his decade-long advocacy for standards to streamline the design flow and maximize productivity and reuse,” Tiner added. “That includes guidance developing the ESG’s major subgroups, oaScript and oaxPop. oaScript provides scripting-language access into the database for Python, tcl, Ruby, and perl, allowing rapid development of user-created tools. oaxPop is the polygon operators extension that makes use of oaScript to provide a Python-based, rapid polygon analysis package for users.”

A 23-year Intel veteran, Masters currently manages an Intel team that enables custom layout capabilities of process nodes, including development of process design kit content. He works with EDA suppliers to improve the overall custom layout of the EDA ecosystem.

IBM, GLOBALFOUNDRIES Enhance Si2 Unified Power Model Standard

Si2 has announced  that IBM and GLOBALFOUNDRIES have contributed patented technology to support the Si2 Unified Power Model standard, the industry’s first significant power model enhancement in many years.

Early stage estimation of System on Chip power consumption is fundamental to ensuring new SoC designs meet or exceed power specifications when fabricated. For a credible estimate, the power models must comprehend the target implementation technology and circuitry, along with voltage and temperature conditions. At the same time, power estimation results are needed quickly in to perform rapid “what if” scenarios.

UPM’s multi-level power modeling capability provides the necessary level of modeling detail required at various stages of design. Abstract high-level equations to gate-level characterization tables can be accommodated through the same, standard interface. Beyond this, the UPM interface, upon acceptance and approval by the IEEE’s P2416 working group, will be a direct plug-in to the widely-used IEEE 1801 stub created for power models.

Simplified Power Modeling

The IBM and GF contributions enhance UPM by providing a new and unique approach to power modeling. Rather than storing pre-characterized, process-voltage-temperature specific data, UPM models store power proxies that represent different contributors to overall power consumption, such as sub-threshold leakage, gate leakage, and dynamic power. Appropriately entitled “power contributors,” this approach vastly simplifies and reduces the power modeling effort, and allows the power model to be voltage and temperature independent, enabling a single power model to be used at a multitude of voltages and temperatures.

SoC designers using UPM with contributor-based modeling will ultimately be equipped with thermally-aware, system-level power estimation. In addition, the late-binding of specific PVT conditions at simulation run-time will provide accurate, early estimates of leakage power, which increases exponentially with increasing temperature. The donated technology covers key aspects of contributor-based power modeling including model abstraction, generation, compression and evaluation.

Contributor-based modeling will be fully integrated into UPM, which forms the basis for P2416, the planned IEEE standard for developing and maintaining interoperable, IC design power models.  P2416 is scheduled for balloting in early 2019.

Industry Contributions

Jerry Frenkil, director of Si2 OpenStandards, said the IBM and GF contributions bolster UPM and provide P2416 with proven and ready-to-use modeling methods.  “These power proxies enable voltage and temperature-independent modeling which greatly reduce the model generation and support effort,” Frenkil explained. “They also enable late binding of voltage and temperature conditions at simulation run-time, a major benefit for both IP developers and SoC designers.”

“IBM is pleased to donate this advanced modeling technology to Si2’s UPM development to facilitate interchange of IP power data,” said Dr. Leon Stok, vice president of EDA at IBM.  “We have used contributor modeling internally on several generations of IBM micro-processors to great effect. We look forward to seeing UPM contributor models being provided by IP block developers so that entire systems, consisting of both internal and external IP, can be modeled efficiently using a common modeling standard.  Additionally, the combination of power contributors and multi-level modeling structures promises major cost and resource improvements in creating and supporting IP power models.”

“UPM directly addresses a major industry need—accurate and efficient system-level power models,” said Richard Trihy, senior director of design enablement at GF.  “Since IP providers need only produce a single model for a multitude of PVT points, these models enable significant productivity gains in model generation. Our clients will also get a good early estimate of their systems’ total power, including leakage, which can operate at high temperatures.”

Ready for P2416 Balloting

“These contributions from IBM and GF come at a fortuitous time,” said Dr. Nagu Dhanwada of IBM, chair of the IEEE P2416 Working Group and the Si2 UPM development project.  “The P2416 Working Group is rapidly gathering momentum towards IEEE standardization.  We anticipate going to ballot early next year.”
