In the realm of ESD protection, Charged Device Model (CDM) is becoming the biggest challenge. Of course, Human Body Model (HBM) is still essential, and needs to be used when verifying chips. However, a number of factors are raising the potential losses that CDM events can cause relative to HBM. These factors fall into two categories:… Read More
Coupled Electro-thermal Analysis Essential for PowerMOS Design
Power device designers know that when they see a deceptively simple pair of PowerMOS device symbols in the output stage of a power converter circuit schematic, they are actually looking at a massively complex network of silicon and metal interconnect. The corresponding physical devices can have a total device W on the order of … Read More
Verifying ESD Fixes Faster with Incremental Analysis
The author of this article, Dündar Dumlugöl, is CEO of Magwel. He has 25 years of experience in EDA managing the development of leading products used for circuit simulation and high-level system design.
Every designer knows how tedious it can be to shuttle back and forth between their layout tool and analysis tools. Every time an… Read More
Snapback behavior determines ESD protection effectiveness
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
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
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
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?
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
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
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
