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 ...

Rather, for a high-speed clock, the interval measurements represent an undersampled subset of the clock intervals selected from a much larger number of clock cycles. Traditional equivalent-time ...

This week we will look at standard synchronization techniques for multi-clock domain SoCs and FPGAs. Let us begin with the most common and simple option. In general, a conventional two flip-flop ...

Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...

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 ...

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 ...

At the heart of all computers is a clock, a dedicated timepiece ensuring that all of the parts of the computer are synchronized and can work together to execute the instructions that the computer ...

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.
