10nm And 7nm Routability – How Is Your CAD Flow Doing?
By Tobias Bjerregaard - 09 Mar, 2017 - Comments: 0

At DesignCon in January, I was a panelist at a panel session entitled “Power Integrity For 10nm/7nm SoCs - Overcoming Physical Design Challenges And TAT.” I was on the panel together with Arvind Vel, Sr. Director Applications Engineering, ANSYS, Inc. and Ruggero Castagnetti, Distinguished Engineer, Broadcom Limited. This topic is of course extremely broad, but it was interesting getting fee... » read more

New USB Audio Class For USB Type-C Digital Headsets
By Morten Christiansen - 09 Mar, 2017 - Comments: 0

The ¼” phone jack was invented more than 100 years ago to connect people using a new invention called the “telephone.” Today, the modern variant - the 3.5mm phone jack - is widely used. As modern mobile phones are used for more than phone calls and do not have room for multiple connectors, a new approach for audio connectivity is needed, so product designers are retiring the 3.5mm jack. ... » read more

Correlating Software Execution With Switching Activity To Save Power In SoC Designs
By Russell Klein - 09 Mar, 2017 - Comments: 0

There is probably no more pointless waste of energy than lighting and heating a room that is empty. The obvious optimization: notice that no one is there and turn off the lights. It works the same on an SoC or embedded system. To save energy, system developers are adding the ability turn off the parts of the system that are not being used. Big energy savings but with no compromise to functional... » read more

Debug Is About To Get Really Interesting Again
By Antonio Russo - 09 Mar, 2017 - Comments: 0

One of the great unheralded chapters in the history of electronics design is debug. After all, where there have been designs, there have been bugs. And there was debug, engaged in an epic wrestling match with faults, bugs and errors to determine which would prevail. Think about system in the 1970s and '80s. A typical system would consist of a CPU, (EP)ROM, RAM, Peripherals (PIC, UART, DMA, T... » read more

Adapting Formal
By Ann Mutschler - 09 Feb, 2017 - Comments: 2

With more pressure to make designs efficient — from a power perspective, as well as from an overall design view — finding what can be removed from a design is one step closer. As discussed in the article published today, “What Can Be Cut From A Design?” — sequential analysis, based on formal verification technology, is gaining traction. I specifically asked Mentor Graphics’ direc... » read more

Confidence In 7nm Designs Requires Multi-Variable, Multi-Scenario Analysis
By Sankar Ramachandran - 09 Feb, 2017 - Comments: 0

As designs move toward 7-nanometer (nm) process nodes, engineering and production cost dramatically increases and the stake in getting the design right the first time becomes significantly higher than ever before. You are faced with the question, “how confident are you in your design analysis coverage?” Tighter noise margin, increasing power density, faster switching current and greater ... » read more

The Challenges Of Designing An HBM2 PHY
By Frank Ferro - 09 Feb, 2017 - Comments: 1

Originally targeted at the graphics industry, HBM continues to gain momentum in the server and networking markets as system designers work to move higher bandwidth closer to the CPU. Expanding DRAM capacity – which boosts overall system performance – allows data centers to maximize local DRAM storage for wide throughput. HBM DRAM architecture effectively increases system memory bandwidth... » read more

Real-Time Virtualization – How Hard Can It Be?
By Jon Taylor - 09 Feb, 2017 - Comments: 0

What’s the first association you make when you hear of virtualization? Server farms? ‘The cloud’? Most people don’t think of embedded systems - never mind hard real-time - yet these are areas where virtualization is now becoming commonplace. Markets such as industrial, automotive and medical—many of which also have requirements around functional safety for products like car braking... » read more

Finding The Unexpected In High Performance Designs
By Russell Klein - 09 Feb, 2017 - Comments: 0

It was growing dark as I drove a winding road on Mt. Hood, deep in the American northwest forest. The firs were thick, creating a lot of shadows and making it tough to see things clearly. Then out of the corner of my eye, I swear I saw a 10-foot “man” covered with brown fur. It looked a lot like a Wookie. But everyone knows Wookies aren’t real. It had to be Bigfoot! I slammed on th... » read more

TSMC: 10nm To Be Greater Than 10% Of 2017 Wafer Revenue
By Barry Pangrle - 18 Jan, 2017 - Comments: 2

TSMC’s financial results for the 4th Quarter of 2016 were released on January 11, 2017 (PST) and showed that year-over-year fourth quarter revenue increased 28.8% and simultaneously net income and diluted EPS both increased 37.6%.  In U.S. dollars, TSMC’s fourth quarter revenue was $8.25 billion. TSMC's CFO, Ms. Lora Ho, reported that 2016 was a good year for TSMC and that the company set ... » read more
