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

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.
- Exploring XML
— XML editors
— What is XML and why do we use it?
— How do you use OPS XML?
— What is a valid XML file?
- XML File Format
— XML prologue and comments
— XML element declaration
— Sub-elements and content value
- Namespaces and Schemas
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.

AUSTIN, Texas–Silicon Integration Initiative (Si2), an Austin-based integrated circuit research and development joint venture, has launched a project to help designers reduce power consumption, a growing challenge for most system-on-chip designs. The project will develop new power modeling technology to estimate power consumption more easily and more accurately throughout the design process, especially during the earliest stages.
The end result will be a new power modeling standard to reduce resources and costs needed to develop virtually every type of SoC. Jerry Frenkil, director of OpenStandards, said that the Si2 Low Power Working Group, part of the newly restructured Si2 OpenStandards program, will lead this industry-wide effort.
“Every SoC design team is grappling with the continued need to reduce power consumption,” Frenkil said. “That’s especially true for mobile devices, but it’s also a concern throughout the electronics industry. One way to accomplish this is through improved multi-level power modeling techniques that better predict SoC power and performance. Right now there’s no commonly accepted way to develop an accurate estimation of power consumption early in the design phase. This often leads to designs being power inefficient, performance constrained, or both.”
Frenkil said the standard will also “enable more efficient and reliable power analyses and optimizations since the same model will be used from system-level design through gate level implementation and all phases in between.”
The approved specification will be contributed to the IEEE P2416 Standards Working Group for industry-wide distribution. Nagu Dhanwada, senior R&D engineer at IBM, chairs both the IEEE P2416 and Si2 Low Power Modeling Working Groups. “Since Si2 is an R&D joint venture, its members can work together to develop specifications, tests and proof-of-concepts with anti-trust protection. This specification will greatly accelerate standardization efforts within P2416, and testing prior to IEEE standardization will enable us to rapidly prove out the use of the new standard before it hits the street,” Dhanwada explained.
IEEE P2416 is an essential component of a coordinated IEEE effort focusing on system-level design. The IEEE 1801 standard currently expresses design intent. It’s latest update, IEEE 1801-2015, includes support for power modeling.
John Biggs, co-founder and consultant engineer at ARM, chairs the IEEE 1801 Working Group. “Efforts of the Si2 Low Power Working Group will help the IEEE P2416 Working Group standardize the representation of power consumption data,” Biggs said. The fruits of this work, in combination with the new power modeling capability in IEEE 1801-2015, should greatly ease the challenging task of energy-aware system level design.”
The new Si2 model specification is expected to be completed in October. For more information about this project, contact Jerry Frenkil at Jfrenkil@si2.org. For information about the Low Power Working Group and other OpenStandards programs, visit http://www.si2.org/openstandards/.
Founded in 1988, Si2 is a leading research and development joint venture that provides standard interoperability solutions for integrated circuit design tools. All Si2 activities are carried out under the auspices of the The National Cooperative Research and Production Act of 1993, the fundamental law that defines R&D joint ventures and offers them a large measure of protection against federal antitrust laws. Si2’s international membership includes semiconductor foundries, fabless manufacturers, and EDA companies.
