    A solar eclipse occurs when the moon comes between the earth and the sun, and the moon casts its shadow on the earth. During the few minutes of totality the entire disk of the sun is blocked and its delicate corona can be seen. These panoramic images show the entire horizon during a total solar eclipse. Just…

    Flow Engineering for Physical Implementation: Theory and Practice by Steve Golson and Pete Churchill Abstract: EDA tools are never used in isolation. Rather, multiple tools are combined into a sequence called a flow. Furthermore an elaborate infrastructure is required to support and enable flow execution. This flow infrastructure includes directory organization, configuration management, compute servers,…

    The four largest moons of Jupiter were discovered by Galileo in early 1610 when he first turned his telescope toward the heavens. They are called the Galilean moons in his honor. In a single evening you can observe them move in their orbits around Jupiter; visual proof that Copernicus was correct and our earth is not the…

    In March 1610 Galileo published his book Sidereus Nuncius [The Starry Messenger] containing the first astronomical observations ever made with a telescope. Among other wonders in this masterwork are the first drawings and descriptions of mountains on the moon: …very many bright points [that] appear within the dark part of the Moon, entirely separated and removed from…

    An annular eclipse occurs when the moon comes between the earth and the sun, however the moon appears smaller than the sun and thus never completely blocks it. At maximum coverage observers on the eclipse track will see a ring of sunlight around the moon. The name comes from the Latin word annulus meaning ‘ring.’ The final…

    The Human ECO Compiler by Steve Golson Abstract: Engineering Change Orders or ECOs are all too prevalent in ASIC design. Unfortunately there are few tools that directly support these “last minute” changes to a design. So it’s left to us humans to figure out a solution. This paper will cover the ad hoc solutions that have been developed for…

    Asynchronous & Synchronous Reset Design Techniques – Part Deux by Clifford E. Cummings, Don Mills, and Steve Golson Abstract: This paper will investigate the pros and cons of synchronous and asynchronous resets. It will then look at usage of each type of reset followed by recommendations for proper usage of each type. I recommend you use synchronous…

    The word galaxy comes from the ancient Greek galaxias kuklos meaning ‘milky band’. Our own galaxy consists of several hundred billion stars in the shape of a spiral-armed disk some 100,000 light-years across. Far from city lights we can see this disk edge-on: thousands of stars sweeping across the dark summer sky. Milky Way in Cygnus Taken August 23,…
