Blog Review: Aug. 21


Cadence's Reela Samuel explores the critical role of PCIe 6.0 equalization in maintaining signal integrity and solutions to mitigate verification challenges, such as creating checkers to verify all symbols of TS0, ensuring the correct functioning of scrambling, and monitoring phase and LTSSM state transitions. Siemens' John McMillan introduces an advanced packaging flow for Intel's Embedded ... » read more

EUV mirror interference lithography Researchers from the Paul Scherrer Institute developed an EUV lithography technique that can produce conductive tracks with a separation of just five nanometers by exposing the sample indirectly rather than directly. Called EUV mirror interference lithography (MIL), the technique uses two mutually coherent beams that are reflected onto the wafer by two id... » read more

3D X-ray of chip interiors Researchers from the Paul Scherrer Institute, EPFL Lausanne, ETH Zurich, and the University of Southern California used X-rays to take non-destructive, three-dimensional images of the inside of a microchip at 4 nanometer resolution. To create the images, the researchers relied on a technique called ptychography, in which a computer combines many individual images ... » read more

Synopsys' Jyotika Athavale and Randy Fish investigate the problem of silent data corruption caused by difficult-to-detect hardware defects that cause unnoticed errors in the data being processed and is becoming an increasingly pressing problem as computing scales massively at a rapid pace with the demands of AI. Siemens' Keith Felton suggests adopting physical design reuse circuits to provid... » read more

Measuring temperature with neutrons Researchers from Osaka University, National Institutes for Quantum Science and Technology, Hokkaido University, Japan Atomic Energy Agency, and Tokamak Energy developed a way to rapidly measure the temperature of electronic components inside a device using neutrons. The technique, called ‘neutron resonance absorption’ (NRA), examines neutrons being ab... » read more

Cadence's Jasmine Makhija explains how to boost the performance of CXL 3.0 by using NOP (No Operation) Insertion Hints in latency-optimized 256B Flit Mode, which enables the system to quickly revert to the low-latency path after temporarily switching to a higher-latency path due to error correction needs. Synopsys' Robert Fey finds that by automatically and dynamically linking requirements a... » read more

Embedded thermoelectric devices Researchers from the University of Pittsburgh and Carnegie Mellon University propose using locally embedded thermoelectric devices (TEDs) to perform active cooling inside circuits. “Circuits like clock generators and arithmetic and logic units (ALU) create high-frequency heat fluxes with their peak hot spots occurring on the microprocessor,” said Feng Xio... » read more

Sub-1nm gate Researchers from Korea's Institute for Basic Science, Sungkyunkwan University, Harvard University, and Korea Advanced Institute of Science and Technology (KAIST) found a method that enables epitaxial growth of 1D metallic materials with a width of less than 1 nm, which they used as a gate electrode of a miniaturized transistor. The team controlled the crystal structure of molyb... » read more

Blog Review: July 17


Cadence's Xin Mu explains the PCIe ECN Unordered IO (UIO) feature in the PCIe 6.1 specification, which defines a new wire semantic and related capabilities to enable multiple-path fabric support and helps avoid unnecessary traffic for better bandwidth and latency. Synopsys' Dana Neustadter, Gary Ruggles, and Richard Solomon highlight the latest updates in the CXL 3.1 standard, including new ... » read more
