2002 International HDL Conference (HDLCon 2002)
Panel: The Value of Verification Abstract: The debate over verification continues unabated over how critical a role it plays in the overall design process. In some circles, it is viewed as essential and valuable. Even so, there are questions over which verification tools are necessary and what tools work. Project teams need to determine whether…

What is popularly known as a “shooting star” is more correctly called a meteor. It is the luminous phenomenon caused when a small particle (a meteoroid) enters the earth’s atmosphere and vaporizes. A typical meteoroid is smaller than a grain of rice, is moving at 12km/s to 72km/s (25,000 to 160,000 mph), and is completely vaporized by…

A Comparison of Hierarchical Compile Strategies by Steve Golson Abstract: A wealth of new hierarchical compile strategies have become available in the last few years. This paper will compare area, speed, and compile time for several large designs using a variety of hierarchical compile strategies: top-down compile, top-down simple compile, bottom-up with default constraints, bottom-up with hand-crafted constraints, and ACS…

Most prominent of the moon’s surface features are the large dark areas called maria (Latin for ‘seas’), so named because early 17th century astronomers thought they contained water. Actually the maria are circular basins filled with layers of basaltic lava, which flowed out of the moon after a large meteorite impact excavated the basin. The maria are…

Levels of Abstraction: The History of Custom MOS Design by Steve Golson For the Tenth SNUG in 2000, Kurt Baty organized a panel discussion that reviewed progress in synthesis, simulation, and EDA tools in general over the past decade. Here are the slides from my presentation covering the history and possible future of ASIC design.

The path of the setting sun makes an angle with the horizon that varies directly with latitude. At the equator (latitude 0°) the sun’s path is perpendicular to the horizon, while near Boston (latitude 42°N) the sun’s path makes a 48° angle. The angle stays the same throughout the year; the point of intersection (sunset)…

Resistance is Futile! Building Better Wireload Models by Steve Golson Abstract: Wireload models are like the weather. Many people talk about them, but not many people do anything about them! This paper will explore some of the myths and realities of wireload models: why wireload models are important, and why nobody understands them why your…

Push-button synthesis or, using dc_perl to do_the_right_thing by Kurt Baty and Steve Golson Abstract: We have developed a methodology to automatically synthesize large hierarchical designs. This methodology combines the advantages of bottom-up compilation with top-down rebudgeting. Starting with only the Verilog source code, all required makefiles, synthesis scripts, and constraint files are automatically derived. An…
