Synchronous interfaces involve a single clock domain and are relatively easy to design. However, at times, it is advantageous and necessary to have an asynchronous interface between peripherals for ...

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 ...

Whether designing SOCs with traditional synchronous logic or alternative locally, or self-clocked "asynchronous" blocks, verification has become more important, difficult and time consuming, ...

No discussion on FPGA design is complete without addressing the issues associated with transferring signals that are not synchronized to the clock into clocked logic. While this should be a digital ...

Today's SOC (system-on-chip) designs have dozens of clocks, many of which are asynchronous. This design approach facilitates the convergence of digital-audio, video, wireless, and networking ...
