Securing 4K Content And Beyond Over HDMI
By Angela Raucher - 09 Apr, 2015 - Comments: 0

By Angela Raucher & Dana Neustadter As we move into the era of transmitting and receiving 4K Ultra-High Definition (UHD), High Dynamic Range (HDR) and even 8K UHD content, robust security becomes even more important for the protection of premium content. Today, High-Definition Multimedia Interface (HDMI) is the most widely used, and sometimes the only interface to connect high-resolution c... » read more

What Is Coherency?
By Neil Parris - 09 Apr, 2015 - Comments: 0

Coherency is about ensuring all processors, or bus masters in the system see the same view of memory. Cache coherency means that all components have the same view of shared data. Just as you need both of your eyes to have the same view in order to see properly, it’s critical for every IP block that has access to a shared data source to view consistent data. For example, if I have a process... » read more

TSMC: Rise of the “Phantom Node”
By Barry Pangrle - 23 Mar, 2015 - Comments: 0

TSMC’s financial results for Q4 of 2014 and for the full year were announced in January with TSMC stating it again had achieved record sales and profits. The fourth quarter saw TSMC set records for revenue, earnings per share and cash balance. TSMC made bold predictions last year about 20nm revenue by Q4 2014, and it appears it has met them (see 28nm Powers TSMC Forward, Part Deux). TSMC repo... » read more

Low Power Paradox
By Anand Iyer - 13 Mar, 2015 - Comments: 0

Power has been an important design challenge for quite some time. Leakage power started to grow in 90nm, and by 65nm it became a severe design issue. We have built many techniques to address leakage, most notably power gating. These techniques are complex and have an impact on the design as a whole. FinFET technologies are seen as a boon to this issue of leakage. There are references that qu... » read more

Where Did Auto Innovation Begin?
By Ann Mutschler - 12 Mar, 2015 - Comments: 0

As far as how the current wave of electronic innovation started happening in the automotive industry, the genesis is likely multi-faceted. During a recent conversation, Cadence Fellow Chris Rowen recalled that there was an underlying recognition that the big opportunity to add value to a vehicle came from electronic systems and a recognition that there was a theoretical capability, for examp... » read more

Package Modeling Needs For A Robust IC Power Integrity Sign-Off
By Chris Ortiz - 12 Mar, 2015 - Comments: 0

Progress in IC technology has allowed chip designers to pack more functionality and continually make better use of silicon area. This trend, coupled with the need to maintain low power using techniques such as voltage islands and power and clock gating, has caused the power consumption to vary across the chip and over time. This has introduced considerable amount of transient current peaks in t... » read more

Modeling High-Performance Analog And RF Circuits In Nanometer-Scale CMOS
By Mentor, a Siemens Business - 12 Mar, 2015 - Comments: 0

By Mick Tegethoff and David Lee Today’s consumer, communication, and computer electronic devices have clocks, communication interfaces, and high-speed signal-conditioning circuits that operate at radio frequencies (RF). Providing price-competitive products often requires monolithic integration of these circuits in low-power nanometer-scale bulk CMOS silicon. This is a worst-case scenario for... » read more

Clock Domain Crossing (CDC): Are We There Yet?
By Ravindra Aneja - 12 Mar, 2015 - Comments: 0

Over the last decade, SoC designs have become significantly reliant on IP reuse to manage the design complexity and meet time-to-market goals. IP-based design and verification methodology is essential but has put an additional verification burden on IP suppliers (internal and external). IP suppliers need to ensure that their IP is exhaustively verified and SoC Integrators need to ensure that al... » read more

Extending UPF For Use In System-Level Design
By Alan Gibbons - 12 Mar, 2015 - Comments: 0

Energy efficiency as a design constraint continues to dominate, and now that we see greater momentum behind a shift left toward system-level design, we are naturally seeing power-aware system-level design as a key area for EDA and IP enablement, especially among mobile and IoT platform providers. In my last article I highlighted the role that IP power models play in the architecture and design ... » read more

With Object-Based Audio, Dizzying Design Possibilities
By Brian Fuller - 12 Mar, 2015 - Comments: 0

Technology innovation can be dizzying—literally. Walk through a place as vast and cavernous as Mobile World Congress (and walk and walk and walk) and you can’t help but get wobbly at all the innovation in the building. But find your way to the Fraunhofer booth and things get even more interesting. Here, you take a seat outside the booth, slip on a virtual reality headset and settle ... » read more
