Snapback behavior determines ESD protection effectiveness

Snapback behavior determines ESD protection effectiveness
by Tom Simon on 12-14-2017 at 12:00 pm

Terms like avalanche breakdown and impact ionization sound like they come from the world of science fiction. They do indeed come from a high stakes world, but one that plays out over and over again here and now, on a microscopic scale in semiconductor devices – namely as part of electrostatic discharge (ESD) protection. Semiconductor… Read More


SRAM Optimization Saves Power on SOC’s and in Systems

SRAM Optimization Saves Power on SOC’s and in Systems
by Tom Simon on 03-21-2017 at 12:00 pm

Mobile device designers face the dilemma of reducing power and at the same time maintaining or increasing performance. Consumers will not tolerate increased battery life at the expense of performance. If it were otherwise, designers could simply dial back clock rates. Without this simple cure, the best way to reduce power for… Read More


On-Chip Power Distribution Networks Get Help from Magwel’s RNi

On-Chip Power Distribution Networks Get Help from Magwel’s RNi
by Tom Simon on 02-02-2017 at 12:00 pm

Counting squares is a useful tool for calculating simple resistance in wires, but falls short in reality when wires deviate from ideal. Frequently the use of RC extraction tools for determining resistance in signal lines in digital designs can be effective and straightforward. However, there are classes of nets in designs that… Read More


CEO Interview: Dündar Dumlugöl of Magwel

CEO Interview: Dündar Dumlugöl of Magwel
by Tom Simon on 12-19-2016 at 7:00 am

Magwel CEO Dündar Dumlugöl is well known from his days at Cadence, where I first met him, and for his more recent tenure at Magwel. At Cadence he led the team that first developed Spectre. He has come a long way from the start of his career at IMEC in Belgium. He and I had a chance to have a conversation recently where he offered insights … Read More


Who protects power protection chips?

Who protects power protection chips?
by Tom Simon on 05-25-2016 at 12:00 pm

Power protection chips are widely used these days to protect sensitive circuitry from over-voltage and over-current stress. However, these workhorse chips are often subjected to extraordinary thermal stress themselves and need to be protected from burning up – literally.

Power protection chips work like electronic fuses,… Read More


Magwel’s Current Tools Take an Active Role in Power Transistor Design

Magwel’s Current Tools Take an Active Role in Power Transistor Design
by Tom Simon on 12-03-2015 at 7:00 am

It often seems that semiconductor industry coverage focuses on large digital markets like microprocessors or high frequency analog designs for RF applications. Yes, these are large markets, but power transistors like IBGT and VFETS make up a large and crucial sector. Not only do they make their way into discretes, but they are… Read More


How Magwel is Tapping Tried and True Business Strategy in Targeting ESD

How Magwel is Tapping Tried and True Business Strategy in Targeting ESD
by Tom Simon on 11-02-2015 at 12:00 pm

Often when a company starts out it takes a while for it to find the sweet spot in the marketplace. Very often it is feedback from existing customers and business success that can help point the way for small companies as they grow. This is just as true in EDA as it is in retailing or consumer products. For instance, Mentor Graphics, though… Read More


ESD Protection Network Checking is Difficult But Necessary

ESD Protection Network Checking is Difficult But Necessary
by Tom Simon on 06-06-2015 at 6:00 pm

I’ve written before about anti-fuse non-volatile memory, where the gate oxide is intentionally damaged in order to create a readable bit of data, but this is what most circuit designers never want to have happen to their logic gates. However, since the advent of MOS transistors the issue of Electrostatic Discharge (ESD) and the… Read More


CTO Interview with Dr. Wim Schoenmaker of Magwel

CTO Interview with Dr. Wim Schoenmaker of Magwel
by Daniel Payne on 12-09-2014 at 7:00 pm

I visited the Magwelbooth at DACin June and chatted with Dundar Dumlugol the CEO about their EDA tools that enable 3D co-simulation and extraction. Since then I’ve made contact with their CTO, Dr. Wim Schoenmaker to better understand what it’s like to start up and run an EDA company. Magwel’s history goes back… Read More


Electro-Thermal Simulation of Power Transistors

Electro-Thermal Simulation of Power Transistors
by Daniel Payne on 09-25-2014 at 4:00 pm

Power transistors are commonly used in applications like: hybrid vehicles, electric vehicles, automotive, home appliances, LED lighting, TVs, power and energy. In the old days an engineering team could build their device with power transistors, then after production run some thermal testing to see if they guessed the proper… Read More
