A Different Kind Of Material World
By Ed Sperling - 21 Mar, 2019 - Comments: 1

The semiconductor manufacturing world is poised for big change, and the driver will be materials. Materials always have been a critical factor in semiconductors. Silicon is so important that an entire region of California is named after it. Rare earths have raised fears about nationalistic monopolies. And the shift from aluminum to copper interconnects at 130nm caused one of the most painful... » read more

Blog Review: Feb. 20

Synopsys' Chirag Tyagi examines how Display Stream Compression 1.2 allows the commonly used MIPI DSI display interface to support 8k UHD displays in applications like infotainment and AR/VR even with the limited bandwidth of PHY layers. Cadence's Paul McLellan listens in on a panel discussion at DesignCon on how to create PDKs for silicon photonics so non-photonics experts can complete at le... » read more

Mapping The Impact Of Heat On Photonics
By Ed Sperling - 12 Feb, 2019 - Comments: 0

Heat and various types of noise can disrupt optical signals in silicon photonics applications, pushing light into frequencies that generally are filtered out. Unless those filters are adjusted, data may be lost or incomplete, and in the case of streaming data it may be impossible to reconstruct. But predicting when and how physical effects will affect light isn't always obvious, which makes ... » read more

Analyzing Worst-Case Silicon Photonic Device Performance Through Process Modeling And Optical Simulation
By Ryan Miller - 24 Jan, 2019 - Comments: 0

Silicon photonics is an emerging and rapidly-expanding design platform that promises to enable higher-bandwidth communication and other applications. One of the best qualities of silicon photonics is its ability to leverage existing CMOS fabrication equipment and process flows. However, this means that it is subject to the same process defects and variations. Previous blog posts [References 1,2... » read more

Effects of a Random Process Variation on the Transfer Characteristics of a Fundamental Photonic Integrated Circuit Component
By Coventor - 24 Jan, 2019 - Comments: 0

Silicon photonics is rapidly emerging as a promising technology to enable higher bandwidth, lower energy, and lower latency communication and information processing, and other applications. In silicon photonics, existing CMOS manufacturing infrastructure and techniques are leveraged. However, a key challenge for silicon photonics is the lack of mature models that take into account known CMOS pr... » read more

Week in Review: IoT, Security, Auto
By Jeff Dorsch - 09 Nov, 2018 - Comments: 0

Internet of Things What’s better than a 5G network? How about a local, private 5G network? The Industrial Internet of Things may drive the development of such networks. Of course, 5G cellular communications technology is still being worked out worldwide. BMW, Daimler, and Volkswagen are looking ahead to the future; those automotive manufacturers notified Germany’s Federal Network Agency th... » read more

The Process Design Kit: Protecting Design Know-How
By John Ferguson - 08 Nov, 2018 - Comments: 2

Once upon a time, integrated circuits (ICs) were built by the same companies that designed them. The design of an IC was tightly integrated with the manufacturing processes available within each company. In these days, when designs contained hundreds of transistors, companies modeled each feature in an IC at a first principles level, meaning each transistor or fundamental device was analyzed an... » read more

Physical Verification For Silicon Photonics: Don’t Panic!
By Omar El-Sewefy - 06 Sep, 2018 - Comments: 0

Silicon photonics augments traditional electrical signals in integrated circuits (ICs) with light transmission to speed up data transfer and reduce power consumption. According to MarketsandMarkets, the overall silicon photonics market is worth approximately $774.1M in 2018, and is expected to reach $1,988.2M by 2023, at a CAGR of 20.8% between 2018 and 2023  [1]. Cloud computing is one market... » read more

A Review of Silicon Photonics
By Michael Hargrove - 20 Aug, 2018 - Comments: 0

With the end of Moore’s Law rapidly approaching—some say it's already here—new applications of older technologies are gaining attention. One specific area of interest is photonics. The National Center for Optics and Photonic Education defines photonics as the technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. It can also be... » read more

Design Automation For Silicon Photonics: Pushing Research Into Production
By Chris Cone - 07 Jun, 2018 - Comments: 0

Silicon photonics is a transformative technology that will have a major impact on system architectures in future IC design applications. Already a major solution for Datacom applications and emerging applications in sensing, design techniques in silicon photonics, with the ability to leverage CMOS technology to integrate large numbers of photonic components, are now being applied to enable opti... » read more
