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
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
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
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
I’m keenly interested in SPICE circuit simulators, so at DACI met with John Piercefrom Cadence to get an update on what’s new this year.

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