With the advances of highly phase coherent lasers, optical atomic clocks containing multiple atoms have demonstrated stability that reaches the standard quantum limit (SQL) set by the available atom ...

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 ...

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 ...

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 ...

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 ...

In the previous blog (Synchronization techniques for multi-clock domain SoCs& FPGAs), we studied different types of synchronization techniques to synchronize signals from one clock domain to another.

Clock gating is one of the most frequently used techniques in RTL to reduce dynamic power consumption without affecting the functionality of the design. One method involves inserting gating conditions ...

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 ...
