Containing Design Complexity With POP IP


About 25 years ago, Carver Mead, one of the pioneers of VLSI design, told a technical audience then grappling with the complexities of quarter-micron design that he could see an evolutionary path to about 130nm, but after that point, the picture blurred. Flash forward to the present and we’re manufacturing SoCs at 7nm, and the output is truly amazing devices powering applications we and Me... » read more

Die-to-Die Interconnects for Chip Disaggregation


Today, data growth is at an unprecedented pace. We’re now looking at petabytes of data moving into zettabytes. What that translates to is the need for considerably more compute power and much more bandwidth to process all that data. In networking, high-speed SerDes PHYs represent the linchpin for blazing fast back and forth transmission of data in data centers. In turn, demand is increa... » read more

Accelerators Everywhere. Now What?


It's a good time to be a data scientist, but it's about to become much more challenging for software and hardware engineers. Understanding the different types and how data flows is the next path forward in system design. As the number of sources of data rises, creating exponential spikes in the volume of data, entirely new approaches to computing will be required. The problem is understandi... » read more

Aging Analysis Hits Mainstream


Given the ever increasing challenge of designing high-reliability ICs – especially for automotive, medical, industrial, and aerospace and defense applications – the inclusion of aging analysis capabilities is on the rise in EDA tools as well as design IP. The issue comes down to predictability of devices as they operate. As discussed in, “Taming NBTI To Improve Device Reliability,” t... » read more

The Process Design Kit: Protecting Design Know-How


Once upon a time, integrated circuits (ICs) were built by the same companies that designed them. The design of an IC was tightly integrated with the manufacturing processes available within each company. In these days, when designs contained hundreds of transistors, companies modeled each feature in an IC at a first principles level, meaning each transistor or fundamental device was analyzed an... » read more

Interaction Of Hard IP And Chip-Package


Current and future customer-specific circuit development requires an increasing number of different interfaces, such as for memory (DDR3, DDR4, LPDDR3, LPDDR4, etc.), radio interfaces (Bluetooth, NBIoT, etc.) or high-speed LVDS/SERDES interfaces (DisplayPort, Ethernet, USB, etc.). For customer-specific circuit projects, these components are frequently purchased as hard IP because the developmen... » read more

Next-Generation Ethernet Interconnects For 400G Hyperscale Data Centers


The need for higher bandwidth with efficient connectivity increases as hyperscale data centers transition to faster, flatter, and more scalable network architectures, such as the 2-tier leaf-spine, as seen in Figure 1. The leaf-spine architecture requires massive interconnects as each leaf switch fans-out to every spine switch, maximizing connectivity between servers. Hardware accelerators, art... » read more

Psst, Says 5G… Wanna See What My New Antenna Tech Challenge Looks Like?


5G offers incredible potential, enabling 1000X more traffic, 10X faster speeds and an increase in the device battery capacity by 10X! So why hasn’t 5G technology been rolled out yet? The benefits all sound great, but there are also some challenges that need to be addressed. 5G is destined to cause a revolution around the world with burgeoning industries like autonomous driving, internet of... » read more

Making AI Run Faster


The semiconductor industry has woken up to the fact that heterogeneous computing is the way forward and that inferencing will require more than a GPU or a CPU. The numbers being bandied about by the 30 or so companies working on this problem are 100X improvements in performance. But how to get there isn't so simple. It requires four major changes, as well as some other architectural shifts. ... » read more
