Chiplets: Current Status


Recent weeks have seen a number of interesting developments in the area of chiplets. An increasing number of products based on chiplets have been brought to market, especially in the processors segment. For example, Apple and AMD now have processors with chiplets on the market and under production in high volumes. On one hand, this means that sufficient production capacity has now been built up... » read more

Clocks Getting Skewed Up


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 physical level. To some, the clock is the AC power supply of the chip. To others, it is an analog network almost beyond analysis. Ironically, there are no languages to describe clocking, few tools t... » read more

UCIe: Marketing Ruins It Again


You may have seen the press release and articles recently about a new standard called UCIe. It stands for Universal Chiplet Interconnect Express. The standard is a great idea and will certainly help the market for chiplet-based designs to advance. But the name — Argggh. More on that later. First, let's talk about what it is. You may notice the name looks similar to PCIe (Peripheral Compone... » read more

Chiplets Enter The Supercomputer Race


Several entities from various nations are racing each other to deliver and deploy chiplet-based exascale supercomputers, a new class of systems that are 1,000x faster than today’s supercomputers. The latest exascale supercomputer CPU and GPU designs mix and match complex dies in advanced packages, adding a new level of flexibility and customization for supercomputers. For years, various na... » read more
