It is a new year but those design issues you could not fix last year are still robbing your company’s productivity. The problems didn’t stop at the beginning of this year, and there are less time and limited staff to find the solutions. Well, you are not the only one. In my many years as a corporate application engineer for a large EDA company, I’ve heard the same stories told again and again, with slight variations and a different cast of characters. If I could only get them in the same room, we could discuss the insights to solve these common problems, but that could be collusion with all its consequences.
In 2017, you are no longer alone. The Special Interest Groups (SIG) set up under the anti-trust protection of Si2 allow you to solve design problems with other companies in the industry, sharing hundreds of years of knowledge of designers to address common issues. Si2, as a research and development joint venture, provides an opportunity to collaborate with like-minded companies to identify, document and even solve problems in the electronics/photonics design fields.
Within the Si2 structure, SIGs can be formed to address general or specific design topics such as Silicon Photonic/Electronic Co-Design, Process Design Kit Generation or Design Migration. The SIGs are the incubator for ideas within the Si2 structure. The SIG can create industry surveys to find and prioritize the issues and work with other industry groups to develop roadmaps. Members can jointly write white papers and present at conferences. Using the Si2 infrastructure, the SIG can spawn projects including prototyping implementations, developing standards and creating training and documentation.
A special interest group gathers the information and incubates the ideas. The multiple SIGs share their expertise. These ideas feed additional groups through papers, standards, workshops and project and prototype requirements. Project implementation is performed by members themselves or through the Si2 Working Groups under OpenStandards with the support of the working group members. The working groups spring up to complete a project, and the results are available to working group members. Some of the projects directly affect production design standards coalitions, OpenAccess and the Compact Model Coalition. Graduate and undergraduate students participate in development under the mentorship of the SIG and working group members to create the standards and implementations and supporting information. All this is done under the protection of Si2.
Si2 primary mission is identifying common problems and providing paths to solutions. Starting with the Special Interest Groups, the Si2 structure efficiently extends the industry’s resources, enabling collaborative development while protecting proprietary IP. What can we help each other with today?
Si2 is a research and development joint venture that provides collaborative research and development leading to accelerated interoperability solutions and standards. As defined by the National Cooperative Research and Production Act of 1993, activities conducted under the auspices and guidance of Si2 receive a large measure of protection against federal anti-trust laws.
Jeshairaj Thakaria is the newest member of the Si2 University Partner Network. The network connects qualified engineering student-partners to their future employers in a program that offers real-world, electronic design automation job experience.
A graduate student at the University of Florida Electrical and Computer Engineering Department, Jeshairaj is majoring in digital and mixed signal IC design. His work for Si2 focuses on redeveloping the oaDebug tool set, which gives developers insight into the Si2 OpenAccess database during the development process. oaDebug and oaDiff are the primary products used to develop OpenAccess applications.

Geoffrey J. Coram of Analog Devices is the new volunteer technical advisor for the Si2 Compact Model Coalition. In this newly created position he advises the coalition on Verilog-A implementation for its standard compact models.
Over the past decade, the preferred language for development and implementation of compact models has shifted from C to Verilog-A. Recognizing the importance of the new language, the CMC officers created this position to assist model developers and help encourage best practices.
A senior member of the IEEE, Geoffrey has been an active CMC participant since 2002 and currently leads the CMC subcommittees on Verilog-A recommended practices and the MOS varactor model. In 2004, he led the efforts of the Accellera Verilog-AMS subcommittee to add compact modeling extensions to that modeling language in Language Reference Manual version 2.2.
Geoffrey joined the internal CAD development and circuit simulation group at Analog Devices after earning a Ph.D. from the Massachusetts Institute of Technology in 2000. His undergraduate degree is from Rice University.
Si2 announces the second in a series of member-only webinars focusing on XML–Introduction to XML Schemas.
XML schemas are the normative definitions of any XML-based standard. The schema defines the domain- specific vocabulary (DSV) and types of values in an XML database. The XML database must conform to its schemas, using the predefined elements and entering values that are compliant with the schema.
10:00 a.m.-11:00 a.m. PST
For more information click here.
Many Si2 OpenStandards are based on XML, the eXtensible Markup Language. XML files have a consistent syntax and, combined with the domain specific vocabulary defined in the Open Process Specification (OPS) schemas, succinctly capture the data used to model the IC fabrication process to the design tools.
The OPS XML database contains the constraints, layers, stacks, devices and rules that represent the fabrication process in a vendor-neutral format. This single source for the data is used to generate process design kits.
About the Course
This introductory course focuses on the XML file syntax that will help you create well-formed XML files. Through lecture, quizzes and labs, you will examine the syntax of XML elements and learn how to create, modify or read and understand an OPS XML file. We will explore the file format, elements and attributes, namespaces and connecting to schemas.
Prerequisites: A willingness to learn XML and an interest in OPS.
The example used in the class is a single OPS XML hierarchy that will be used for future courses in this series. A recording will be available on the Si2 Community web site.
Who Should Attend
Si2 member company employees who work with, create, edit or read XML data files are invited to attend this free webinar.

Future Courses for Si2 Members
Si2 will offer additional XML classes Announcements will be made by email and on our web site, www.si2.org.
Matthew Wheaton, a software engineering professional whose experience includes more than 12 years at IBM, has joined Si2 as a senior programmer. His first responsibility is to take the lead on system builds and membership support of the Si2 OpenAccess database and scripting extensions, including oaScript.
While at IBM, Wheaton specialized in build, test, and delivery of EDA tools before moving into Front End tool development and management of the primitives library.
He has already built and configured a number of Linux hosts to compile oaScript and oaxPop, which were used to deliver the latest oaScript update (v.3.3).
A native of New England, Wheaton has a Bachelor of Arts degree in Computer Science from Western Connecticut State University.
Si2 Members Meeting Set for Monday, June 6,
at the Design Automation Conference in Austin, Texas
AUSTIN, Texas–(BUSINESS WIRE)–The Silicon Integration Initiative (Si2) announced today the election of the 2016-17 board of directors. Board members will be introduced at the Si2 Member Meeting and Reception during the Design Automation Conference (DAC), June 6, 4:00-6:00 p.m., Austin Convention Center, Room A10.
New representatives on the Si2 board are: Humair Mandavia, chief strategy officer, Zuken (6947: TYO) and Richard Trihy, director of Design Infrastructure, GLOBALFOUNDRIES.
Reelected board members are:
“The board of directors plays a critical role in providing strategic direction for Si2,” said John Ellis, president and CEO, Si2. “Technology advances from the semiconductor industry provide the foundation for ongoing innovation throughout the electronics industry. However, electronic system complexity continues to exponentially increase, at the same time that our industry is consolidating and overall growth has slowed,” he added.
“As a result, the need for efficient use of our members’ resources in collaborating on semiconductor and electronic system design tool interoperability has never been greater. To this end, our board determines the priorities for where Si2 resources must be focused,” Ellis said.
