At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...

Asynchronous, or clockless, logic–an alternative to standard digital circuits that avoids many of their problems–is beginning to look attractive for embedded designs in consumer electronics and mobile ...

With increased clock domains in modern ASICs, clock-domain crossing (CDC) has become ubiquitous, indispensable, and essential. Of course, timing is always an issue. High clock speeds and delays in ...

Earlier designs were smaller, less complex, and had simpler clocking. A few years back, verification was much easier and clock modeling was not such a big concern. With the drastic increase in the use ...

One of the most important steps in the design process is to identify how many different clocks to use and how to route them. This article tells you how to use routing resources efficiently.

Typically, near-synchronous operation doesn't occur because the data timing and asynchronous sampling clock are independent. Nevertheless, when the clock rate in this example reaches 1 GS/s, you are ...
