Week In Review: Semiconductor Manufacturing, Test


Nikkei Asia reports the U.S. is urging allies, including Japan, to restrict exports of advanced semiconductors and related technology to China. The U.S. holds 12% of the global semiconductor market, Japan has a 15% share, while Taiwan and South Korea each have about a 20% share. Some U.S. companies have called for other countries to adopt U.S.-style export curbs, arguing it is unfair for only A... » read more

Security Research: Technical Paper Round-Up


A number of hardware security-related technical papers were presented at recent conferences, including the August 2022 USENIX Security Symposium and IEEE’s International Symposium on Hardware Oriented Security and Trust (HOST). Topics include side-channel attacks and defenses (including on-chip mesh interconnect attacks), heterogeneous attacks on cache hierarchies, rowhammer attacks and mitig... » read more

An Escalation of Rowhammer To Rows Beyond Immediate Neighbors


Researchers at Graz University of Technology, Lamarr Security Research, Google, AWS, and Rivos presented this new technical paper titled "Half-Double: Hammering From the Next Row Over" at the USENIX Security Symposium in Boston in August 2022. Abstract: "Rowhammer is a vulnerability in modern DRAM where repeated accesses to one row (the aggressor) give off electrical disturbance whose cumu... » read more

Cloud-Ready Circuit Simulation Accelerates SoC Verification


By Nebabie Kebebew and Nigel Bleasdale Driven by the explosion of big data and expanding applications, chip design complexity is increasing. Applications such as high-performance computing (HPC), the Internet of Things (IoT), automotive, and 5G mobile and communications coupled with advanced process technology nodes require running a large number of circuit simulations to ensure the circuits... » read more

Why Hardware-Dependent Software Is So Critical


Hardware and software are two sides of the same coin, but they often live in different worlds. In the past, hardware and software rarely were designed together, and many companies and products failed because the total solution was unable to deliver. The big question is whether the industry has learned anything since then. At the very least, there is widespread recognition that hardware-depen... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive Suzuki will collaborate with SkyDrive on flying cars. SkyDrive is working on an air taxi service that it wants to launch at the 2025 World Exposition in Osaka, Japan. Recalls: The car company Tesla is recalling 947 vehicles in the United States because rearview image lags and does not display immediately when the car is put into reverse, said the National Highway Traffic Safety A... » read more

How To Justify A Data Center


The breadth of cloud capabilities and improvements in cost and licensing structures is prompting chipmakers to consider offloading at least some of their design work into the cloud. Cloud is a viable business today for semiconductor design. Over the past decade, the interest in moving to cloud computing has grown from an idea that was fun to talk about — but which no one was serious about ... » read more

Week In Review: Design, Low Power


Tools & IP Ansys updated its product suite, adding new tools and workflows in Ansys 2022 R1. It adds Phi Plus meshing technology to improve simulation of PCB and complex 3D IC packaging. It also introduces RedHawk-SC SigmaDVD, a statistically realistic modeling technique to identify the worst-case dynamic voltage-drop in hours and make it possible to achieve near 100% coverage of all relev... » read more

Week In Review: Auto, Security, Pervasive Computing


NASA plans to launch the James Webb Space Telescope (JWST) this Saturday, Dec 25, on an European Space Agency (ESA) rocket. Mission-critical radiation-hardened components from IR HiRel, an Infineon company, will go up with the JWST. IR HiRel space-grade DC-DC converters, rad hard MOSFETs and other power control products are in the spacecraft bus subsystems, such as electrical power, altitude co... » read more

Week In Review: Design, Low Power


Infineon Technologies acquired Syntronixs Asia, which specializes in precision electroplating, a key process in the assembly process of semiconductors. Syntronixs Asia has a workforce of more than 500 people and has been a major service provider for Infineon since 2009. “Through this acquisition, we have made another important step to strengthen the resilience of our supply chain,” said Tho... » read more
