As designs grow larger and process technologies continue to shrink, power becomes an increasingly important design consideration. When designing a printed circuit board (PCB), the power consumed by a device needs to be accurately estimated to develop an appropriate power budget and to design the power supplies and cooling system. The PowerPlay power analysis technology, […]
Considering how complexity has grown over the last 20 years, it is amazing how few dramatic shifts in the design and verification methodology have occurred. When they do happen — mylar to layout tools, gates to RTL, hand-crafted test vectors to testbench automation — they make our work as engineers easier and enable us to […]
If you want to get a clear idea of just what is taxing engineers at any given time, you can do a lot worse than following the trends that emerge before each annual Design Automation Conference (DAC). “And this year, it is pretty clear that there are three things on everyone’s mind: power, system-level design […]
Once upon a time, placing even the smallest question mark next to Moore’s Law was seen as something beyond heresy. Today, more and more people are voicing such thoughts in the mainstream. One of the most senior figures speaking out is Bernard Meyerson, vice president and chief technologist of IBM’s Systems & Technology Group. The […]
Major yield-Inhibiting Issues At each successive process node, additional defect mechanisms appear and hinder the ability to achieve desired yield (Figure 1). The trend toward declining yields has led to a resurgence in the application of design for manufacturing (DFM) methodologies.Much of this reinvigorated effort relies heavily on a new breed of tools and technologies. […]
Semiconductor devices are being fabricated with features that are less than half the wavelength of the available lithography exposure tools. Increasing circuit density has improved the complexity and performance of ICs but also led to serious patterning proximity effects. These effects make the chips almost impossible to fabricate without optical proximity correction (OPC) technology. Thus, […]
