With the increasing complexity of SoCs, multiple and independent clocks are essential in the design. The design specifications require system level muxing of some of these clocks before they are sent ...

Signal integrity is one of the many challenges faced by chip designers. Deep submicron technologies are unfriendly hosts for the nice, clean signals desired. The culprits that compromise signal ...

Signal integrity is the art of getting a signal from point A to point B with minimum distortion to that signal. The recent attention on this subject stems from the necessity to build systems with ever ...

For example, if the positive-going edges of a clock signal are used as the timing reference for a digital circuit, then any deviation of the actual clock edges from their ideal positions constitutes ...

Clocks are power- and area- hungry, and difficult to distribute in a controlled manner. What is being done to reign in these unwieldy beasts? The synchronous digital design paradigm has enabled us to ...

The beating heart of mixed-signal processing is delimited by the clock devices that slice the analog world into digital events. Like our own hearts, we don’t pay much attention to them unless ...

Whether you are sitting at a computer, working on a tablet, talking or surfing on a cell phone, sending data over a network, performing digital signal analysis, or controlling an industrial robot, ...

Lack of coordination between asynchronous resets and synchronous logic clocks leads to intermittent failures on power up. In this series of articles, we discuss the requirements and challenges of ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.

Harrison, born in 1693 in Lincolnshire, proposed a clock design that would solve the problem of determining longitude at sea. His proposal was vindicated last Thursday, 300 years after he first ...
