This work was awarded a best paper award at October's 2022 Institute of Electrical and Electronics Engineers (IEEE)/Association for Computing Machin... » read more

Chip Backdoors: Assessing the Threat


In 2018, Bloomberg Businessweek made an explosive claim: Chinese spies had implanted backdoors in motherboards used by some high-profile customers, including the U.S. Department of Defense. All of those customers issued strongly worded denials. Most reports of hardware backdoors have ended up in exchanges like these. There are allegations and counter-allegations about specifics. But as hardw... » read more

New Approaches For Processor Architectures


Processor vendors are starting to emphasize microarchitectural improvements and data movement over process node scaling, setting the stage for much bigger performance gains in devices that narrowly target what end users are trying to accomplish. The changes are a recognition that domain specificity, and the ability to adjust or adapt designs to unique workloads, are now the best way to impro... » read more

Securing ICs With Information Flow Analysis


Following the data has new meaning when it comes to security. Alric Althoff, senior hardware security engineer at Tortuga Logic, talks about tracking the flow of data through a hardware design over time, including what happens with roots of trust, how this works with existing tools and methodologies, and what to think about when tracing potential security risks. » read more

IoT Merging Into Data-Driven Design


The Internet of Things is becoming more difficult to define and utilize for an effective business strategy. While an increasing number devices send data to the cloud or some local server, so much data is being generated and moved around that new strategies are being developed to rethink what needs to be processed where. Back in 2013, when the IoT concept really began taking off, connectivity... » read more

Chip Industry In Rapid Transition


Wally Rhines, CEO Emeritus at Mentor, a Siemens Business, sat down with Semiconductor Engineering to talk about global economics, AI, the growing emphasis on customization, and the impact of security and higher abstraction levels. What follows are excerpts of that conversation. SE: Where do you see the biggest changes happening across the chip industry? Rhines: 2018 was a hot year for fab... » read more

Security, Scaling and Power


If anyone has doubts about the slowdown and increasing irrelevance of Moore's Law, Intel's official unveiling of its advanced packaging strategy should leave little doubt. Inertia has ended and the roadmap is being rewritten. Intel's discussion of advanced packaging is nothing new. The company has been public about its intentions for years, and started dropping hints back when Pat Gelsinger ... » read more

Open-Source RISC-V Hardware And Security


Semiconductor Engineering sat down with Helena Handschuh, a Rambus fellow; Richard Newell, senior principal product architect at Microsemi, a Microchip Company; and Joseph Kiniry, principal scientist at Galois. What follows are excerpts of that conversation. (L-R) Joseph Kiniry, Helena Handschuh and Richard Newell. SE: Is open-source hardware more secure, or does it just open up vulnera... » read more
