More Knobs, Fewer Markers


The next big thing in chip design may be really big — the price tag. In the past, when things got smaller, so did the cost per transistor. Now they are getting more expensive to design and manufacture, and the cost per transistor is going up along with the number of transistors per area of die, and in many cases even the size of the die. That's not exactly a winning economic formula, which... » read more

Open Source Hardware Risks


Open-source hardware is gaining attention on a variety of fronts, from chiplets and the underlying infrastructure to the ecosystems required to support open-source and hybrid open-source and proprietary designs. Open-source development is hardly a new topic. It has proven to be a successful strategy in the Linux world, but far less so on the hardware side. That is beginning to change, fueled... » read more

Where Technology Breakthroughs Are Needed


After years of delays, extreme ultraviolet (EUV) lithography is finally in production at the 7nm logic node with 5nm in the works. EUV, a next-generation lithography technology, certainly will help chipmakers migrate to the next nodes. But EUV doesn’t solve every problem. Nor does it address all challenges in the semiconductor industry. Not by a long shot. To be sure, the industry needs... » read more

System-in-Package For Heterogeneous Designs


System integration is increasingly being done using 3D packaging technologies rather than integrating everything onto a huge SoC. One motivation is the ability to not just to split up a design in a single process, but to package die from different processes. Sometimes there are economic reasons. Several presentations at HOT CHIPS had a partition of the design into the processor itself, and a... » read more

Multi-Patterning EUV Vs. High-NA EUV


Foundries are finally in production with EUV lithography at 7nm, but chip customers must now decide whether to implement their next designs using EUV-based multiple patterning at 5nm/3nm or wait for a new single-patterning EUV system at 3nm and beyond. This scenario revolves around ASML’s current extreme ultraviolet (EUV) lithography tool (NXE:3400C) versus a completely new EUV system with... » read more

Distributed Design Implementation


PV Srinivas, group director for R&D at Synopsys, talks about the impact of larger chips and increasing complexity on design productivity, why divide-and-conquer doesn’t work so well anymore, and how to reduce the number of blocks that need to be considered to achieve faster timing closure and quicker time to market. » read more

Finding Hardware Trojans


John Hallman, product manager for trust and security at OneSpin Technologies, looks at how to identify hardware Trojans in a design, why IP from different vendors makes this more complicated, and how a digital twin can provide a reference point against which to measure if a design has been compromised. » read more

Speeding Up 3D Design


2.5D and 3D designs have garnered a lot of attention recently, but when should these solutions be considered and what are the dangers associated with them? Each new packaging option trades off one set of constraints and problems for a different set, and in some cases the gains may not be worth it. For other applications, they have no choice. The tooling in place today makes it possible to de... » read more

Power Complexity On The Rise


New chip architectures and custom applications are adding significant challenges to chip design and verification, and the problems are becoming much more complex as low power is added into the mix. Power always has been a consideration in design, but in the past it typically involved different power domains that were either on, off, or in some level of sleep mode. As hardware architectures s... » read more

Accelerating Chiplets With 112G XSR SerDes PHYs


The fading of Moore’s Law and an almost exponential increase in data is challenging the semiconductor industry as never before. Indeed, zettabytes of data are constantly generated by a wide range of devices including IoT endpoints such as vehicles, wearables, smartphones and appliances. Moreover, sophisticated artificial intelligence (AI) and machine learning (ML) applications are adding new ... » read more
