Among the many verification challenges confronting system-on-chip designers these days, clock domain crossings (CDCs) rank near the top in difficulty. Two particularly troublesome CDC-related issues ...

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 ...

With the increasing integration of multiple systems on single SOCs (systems on chip) or boards, multiple clock frequencies in single digital designs have become common. Because of the asynchronous ...

FIFO (First In First Out) is a buffer that stores data in a way that data stored first comes out of the buffer first. Asynchronous FIFO is most widely used in the System-on-Chip (SoC) designs for data ...

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