Reliability sign-off has several aspects – One Solution

Reliability sign-off has several aspects – One Solution
by Pawan Fangaria on 09-01-2013 at 5:00 pm

Here, I am talking about reliability of chip design in the context of electrical effects, not external factors like cosmic rays. So, the electrical factors that could affect reliability of chips could be excessive power dissipation, noise, EM (Electromigration), ESD (Electrostatic Discharge), substrate noise coupling and… Read More


Low-Power Design Analysis and Optimization for Mobile and High-Performance Computing Applications

Low-Power Design Analysis and Optimization for Mobile and High-Performance Computing Applications
by Daniel Payne on 08-23-2013 at 7:36 pm

For several decades now consumers like me have enjoyed using mobile devices including:

  • Transistor radios, my first one had just 6 discreet transistors in the 1960’s
  • HP 21 Calculator, used in college with Reverse Polish Notation, circa 1976
  • Zenith Data Systems laptop, with two floppy drives, 1980’s
  • Palm Pilot V,

An EDA Acquisition that Worked

An EDA Acquisition that Worked
by Daniel Payne on 08-14-2013 at 5:30 pm

I first heard about Andrew Yang back in 1993 when he founded a Fast SPICE company called Anagram, then acquired by Avant! in 1996. Andrew’s latest EDA company Apache Design, Inc.was started in 2001, then acquired by ANSYS in 2011. Most EDA mergers simply don’t work because of one or more reasons, like:

  • Incompatible

RTL Design For Power

RTL Design For Power
by Daniel Payne on 08-11-2013 at 2:25 pm

My Samsung Galaxy Note II lasts about two days on a single battery charge, which is quite the improvement from the Galaxy Note I with only a one day battery charge. Mobile SoCs are being constrained by battery life limitations, and consumers love longer-laster devices.

There are at least two approaches to Design For Power:

  • Gate-level

Power and Reliability Sign-off – A must, but how?

Power and Reliability Sign-off – A must, but how?
by Pawan Fangaria on 07-29-2013 at 11:00 am

At the onset of SoCs with multiple functionalities being packed together at the helm of technologies to improve upon performance and area; power, which was earlier neglected, has become critical and needs special attention in designing SoCs. And there comes reliability considerations as well due to multiple electrical and … Read More


Efficient Power Analysis and Reduction at RTL Level

Efficient Power Analysis and Reduction at RTL Level
by Pawan Fangaria on 07-22-2013 at 12:30 am

It’s a classic and creative example of design and EDA tool community getting together, exploiting tool capabilities and developing flows which add value to all stake holders including the end consumer. We know power has become extremely important for battery life in smart phones, high performance servers, workstations, notebooks… Read More


Full Chip IR Drop Analysis using Distributed Multi Processing

Full Chip IR Drop Analysis using Distributed Multi Processing
by Daniel Payne on 07-02-2013 at 6:56 pm

IR drop analysis across your board, package and SoC ensures that your Power Delivery Network (PDN) is robust, and that your system will function to spec. There are both static and dynamic approaches to IR drop analysis of a full-chip with billions of transistors, while the dynamic approach produces the most accurate results compared… Read More

Today’s Program is Brought To You by the Letter A
by Paul McLellan on 06-28-2013 at 9:09 pm

What do nVidia, Freescale and GlobalFoundries have in common? They are semiconductor companies? They are ARM licensees? They are doing 28nm chips? They all have the letter ‘a’ in their names?

All true, but that’s not what I was thinking of. But the letter ‘a’ is a clue since Apache (and Ansys) begin with ‘a’. All three companies have… Read More

Samsung’s Life of Pi @ Apache @ DAC

Samsung’s Life of Pi @ Apache @ DAC
by Paul McLellan on 05-20-2013 at 4:51 pm

Last week I talked to Eileen You of Samsung-SSI to get a preview on what they will be talking about at Apache’s customer theater at DAC. Their presentation is titledThe Life of PI: SoC Power Integrity from Early Estimation to Design Sign-off. The ‘PI’ stands for Power Integrity.

Samsung-SSI’s operations… Read More
