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 ...

In a recent study done by McKinsey and IDC, we see that physical design and verification costs are increasing exponentially with shrinking transistor sizes. As figure 1 shows, physical design (PD) and ...

While bright light helps us see better, our eyes need darkness for better vision. Light breaks down the sensitive machinery of our eyes every day, and during the darkness of night, key pieces are ...

Promising precise clock generation in networking and other applications, the CY22180 clock achieves a period and cycle-to-cycle jitter output of less than 75 ps over its entire output-frequency range, ...

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 ...

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 ...

For each clock cycle. The phrase "the CPU does four instructions per clock" means that four machine instructions have been executed within one cycle of the CPU clock, the master clock that ...

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 ...

Jitter is a short-term variation in the timing of a digital signal from its nominal value. There are two main types of jitter, random jitter and deterministic jitter. Random jitter is unbounded, that ...

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.
