Timing Channel Attacks are Your Problem Too

Timing Channel Attacks are Your Problem Too
by Bernard Murphy on 08-07-2018 at 7:00 am

You’ve heard about Meltdown and Spectre and you know they’re really bad security bugs (in different ways). If you’ve dug deeper, you know that these problems are related to the speculative execution common in modern processors, and if you dug deeper still you may have learned that underlying both problems are exploits called timing… Read More


CEO Interview: Jason Oberg of Tortuga Logic

CEO Interview: Jason Oberg of Tortuga Logic
by Bernard Murphy on 05-31-2018 at 7:00 am

I first met Jason Oberg, CEO and one of the co-founders of Tortuga Logic, several years ago when I was still at Atrenta. At that time Jason and Jonny Valamehr (also a co-founder and the COO) were looking for partners. The timing wasn’t right, but we’ve stayed in touch, for my part because their area of focus (security) is hot and likely… Read More


Converter Circuit Optimization Gets Powerful New Tool

Converter Circuit Optimization Gets Powerful New Tool
by Tom Simon on 05-09-2018 at 12:00 pm

DC converter circuit efficiency can have a big effect on the battery life of mobile devices. It also can affect power efficiency for wall-power operated circuits. Even before parasitics are factored in, converter circuit designers have a lot of issues to contend with. Optimizing circuit operation is essential for giving consumers… Read More


System Level Formal

System Level Formal
by Bernard Murphy on 01-09-2018 at 7:00 am

Two recently announced vulnerabilities in major processor platforms should remind us that bugs don’t organize themselves to appear only in domains we know how to test comprehensively. Both Meltdown and Spectre (the announced problems) are potential hardware system-level issues allowed by interactions between speculative… Read More


Improved Memory Design, Characterization and Verification

Improved Memory Design, Characterization and Verification
by Daniel Payne on 09-19-2017 at 12:00 pm

My IC design career started out with DRAM design, characterization and verification back in the 1970’s, so I vividly recall how much SPICE circuit simulation was involved, and how little automation we had back in the day, so we tended to cobble together our own scripts to help automate the process a bit. With each new process… Read More


What’s New with Circuit Simulation for Cadence?

What’s New with Circuit Simulation for Cadence?
by Daniel Payne on 06-26-2014 at 11:53 am

Every year at DAC I enjoy making the rounds to see what’s new with SPICE circuit simulators, so on June 3rd I met with Xiuya Liand Dan Zhuof Cadence in San Francisco to get an update about their Spectre tool. There’s plenty of competition in the SPICE area from Mentor Graphics (Analog FastSPICE, Eldo, ADiT), Synopsys … Read More


CDNS V. BDA: Motion to Dismiss

CDNS V. BDA: Motion to Dismiss
by Paul McLellan on 05-02-2013 at 1:00 pm

The Cadence-BDA saga continues with Berkeley Design Automation today filing a motion to dismiss. You can read the full motion HERE. My previous blog “Cadence Sues Berkeley Design Automation” with 30+ comments is HERE.

The first problem BDA brings up is that the DMCA claim by Cadence is so vague that it doesn’t… Read More


Hot Topic – CMOS Image Sensor Verification!

Hot Topic – CMOS Image Sensor Verification!
by Daniel Nenni on 04-29-2013 at 7:30 pm

Mobile applications require CMOS image sensor devices that have a low signal-to-noise ratio (SNR), low power, small area, high resolution, high dynamic range, and high frame rate. CMOS image sensor imaging performance is noise limited requiring accurate noise analysis on the pixel array electronics and column readout circuitry.… Read More


The Ultimate SPICE Circuit Simulator

The Ultimate SPICE Circuit Simulator
by Daniel Payne on 01-03-2011 at 1:19 pm


I love SPICE and Fast SPICE circuit simulators, so here’s my feature list for the ultimate SPICE circuit simulator:

[LIST=1]

  • Input netlists – HSPICE, Spectre, ELDO
  • Multi-core support – parse and simulate fast and accurate
  • LRC Reduction – built-in LRC reduction with a few knobs to control accuracy
  • Tuning
  • Read More
