Physically Aware NoCs


More functions, greater security risks, and increasingly complicated integration of IP and various components below 7nm is increasing the time and effort it takes to get a functioning chip out the door. In many of these devices, the network on chip is the glue between various components, but it can take up to 10% to 12% of the total area of the SoC. Andy Nightingale, vice president of product m... » read more

Screening For Silent Data Errors


Engineers are beginning to understand the causes of silent data errors (SDEs) and the data center failures they cause, both of which can be reduced by increasing test coverage and boosting inspection on critical layers. Silent data errors are so named because if engineers don’t look for them, then they don’t know they exist. Unlike other kinds of faulty behaviors, these errors also can c... » read more

On-Chip Power Distribution Modeling Becomes Essential Below 7nm


Modeling power distribution in SoCs is becoming increasingly important at each new node and in 3D-ICs, where tolerances involving power are much tighter and any mistake can cause functional failures. At mature nodes, where there is more metal, power problems continue to be rare. But at advanced nodes, where chips are running at higher frequencies and still consuming the same or greater power... » read more

Edge-AI Hardware for Extended Reality


New technical paper titled "Memory-Oriented Design-Space Exploration of Edge-AI Hardware for XR Applications" from researchers at Indian Institute of Technology Delhi and Reality Labs Research, Meta. Abstract "Low-Power Edge-AI capabilities are essential for on-device extended reality (XR) applications to support the vision of Metaverse. In this work, we investigate two representative XR w... » read more

Building Complex Chips That Last Longer


Semiconductor Engineering sat down to talk about design challenges in advanced packages and nodes with John Lee, vice president and general manager for semiconductors at Ansys; Shankar Krishnamoorthy, general manager of Synopsys' Design Group; Simon Burke, distinguished engineer at Xilinx; and Andrew Kahng, professor of CSE and ECE at UC San Diego. This discussion was held at the Ansys IDEAS co... » read more

System-Level Benefits Of The Versal Platform


Moore's Law has fueled the technological prosperity of the last 50 years, but it is generally believed now that Gordon Moore's 1965 forecast about the pace of innovation no longer holds true today. Continuing the silicon architectures of yesterday cannot meet the expanding demands of tomorrow's workloads. Frequently highlighted by today’s leaders in the field of computer architecture, to meet... » read more

Behind The Intel-GlobalFoundries Rumor


A Wall Street Journal report that Intel is looking to buy GlobalFoundries has sparked discussions across the industry. But what exactly this would mean, and why now versus a couple years ago, needs some context. There are layers upon layers of irony behind this would-be deal, and it dates back decades to some rather famous encounters. Consider former AMD CEO Jerry Sanders' 1991 comment that ... » read more

The Case For FPGAs In Cars


Field-programmable gate arrays (FPGAs) thrive in rapidly evolving new markets before being replaced by hard-wired ASICs, but in automotive that crossover is likely to happen significantly later than in the past. Historically, FPGAs have held temporary positions until volumes increased enough to cost-reduce the FPGAs out in favor of a hardened version. With automobiles, there are so many chan... » read more

Foundry Wars Begin


Leading-edge foundry vendors are gearing up for a new, high-stakes spending and technology race, setting the stage for a possible shakeup across the semiconductor manufacturing landscape. In March, Intel re-entered the foundry business, positioning itself against Samsung and TSMC at the leading edge, and against a multitude of foundries working at older nodes. Intel announced plans to build ... » read more

Week In Review: Manufacturing, Test


Chipmakers TSMC has posted strong results and raised its capital spending budget to $30 billion, up from its prior guidance of $25 billion to $28 billion in 2021. “Its outlook indicates broad-based semiconductor demand continues to strengthen amid supply chain tightness,” said Weston Twigg, an analyst at KeyBanc, in a research note. “TSMC posted another quarter of strong demand for leadi... » read more
