Reliability for ICs is a big deal because the last thing that you want to do is ship a new part only to find out later in the field that there are failures not being caught by testing. I’ve already had two consumer products fail this year because of probable reliability issues: My MacBook Pro with 16GB of RAM started rebooting caused… Read More
ANSYS acquired Apache Design Automation back in June 2011and three years later the name “Apache” is being subdued in favor of using just ANSYS. One thing that I noticed right away was a DACfocus on having actual ANSYS customers talk about their hands-on experience using the EDA tools. The following seven customers… Read More
There are a few dozen causes of semiconductor failure. Most can be lumped into one of three categories: material defects, process or workmanship issues, or environmental or operational overstress. Even when all those causes are carefully mitigated, one factor is limiting reliability more as geometries shrink – and it… Read More
In most of the electronic equipments, semiconductor chips are a major source of heat generation. And in semiconductor designs several hardware and software techniques are being used to contain power dissipation; a major cause for heat. However due to multiple functionality being squeezed into small form factors, we continue… Read More
Do we ever imagine what kind of severe challenges mission critical unmanned systems in air, land and underwater face? They are limited in space and size; have to be light in weight, flexible in different types of operations and at the same time rugged enough to work in extreme climatic conditions. That’s not enough; amidst these … Read More
With multiple functionalities added into a single chip, be it a SoC or an ASIC, maintaining low power consumption has become critical for any design. Various techniques at the technology as well as design level are employed to accomplish the low power target. These include thinner oxides in transistors, different sections of … Read More
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
There are two ways to see how resistant your designs are to single-event errors (SEE). One is to take the chip or even the entire system and put it in a neutron beam and measure how many problems occur in this extreme environment. While that may be a necessary part of qualification in some very high reliability situations, it is also … Read More
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
How reliable is your cell-phone? Actually, you don’t really care. It will crash from time to time due to software bugs and you’ll throw it away after two or three years. If a few phones also crash due to stray neutrons from outer space or stray alpha particles from the solder balls used in the flip-chip bonding then nobody… Read More
