Blog Review: Jan. 24


Siemens' John McMillan finds that while 3D-IC capabilities are ready for mainstream, mass adoption success depends on how easily, effectively, and efficiently a solution can be delivered and points to five workflow adoption focus areas. Cadence's Andre Baguenie shows how to easily convert a logic signal to an electrical value using Verilog-AMS and the transition filter. Synopsys' Chris Cl... » read more

Memristor-based Bayesian neural network Researchers from CEA-Leti, CEA-List, and CNRS built a complete memristor-based Bayesian neural network implementation for classifying types of arrhythmia recordings with precise aleatoric and epistemic uncertainty. While Bayesian neural networks are useful for at sensory processing applications based on a small amount of noisy input data because they ... » read more

3D stacking of 2D materials Researchers from Penn State University demonstrated monolithic 3D integration with 2D transistors made from 2D semiconductors called transition metal dichalcogenides. The 2D materials have unique electronic and optical properties, including sensitivity to light, making them ideal for use as sensors. “One challenge is the process temperature ceiling of 450 degre... » read more

Startup Funding: December 2023


Photonics and optics were strong in December, with investors funding two different companies using photonic technologies to develop AI chips and interconnects. Another key area — metaoptics — combines what traditionally would be separate lenses and optical components into a single, flat nanopatterned device. Metaoptics are being deployed in applications ranging from AI processing and sensor... » read more

High mobility graphene Researchers at the Georgia Institute of Technology and Tianjin University created a functional semiconductor made from graphene that is compatible with conventional microelectronics processing methods. "We now have an extremely robust graphene semiconductor with 10 times the mobility of silicon, and which also has unique properties not available in silicon," said Walt... » read more

Trendspotting: Automotive IC Startup Funding In 2023


Consumers expect a lot from the electronics in their cars. The parts in the safety-critical systems need to be reliable for up to 18 years, able to handle a range of temperatures, voltages, and vibrations — and all the while be fault-tolerant and make zero errors. On top of those basic requirements, automakers trying to appeal to consumers are adding in more features that communicate with the... » read more

Blog Review: Jan. 3


Siemens' Stephen Ferguson looks at the history of computer aided engineering through the lens of how humans interact with computers, with each development enabling a step change in engineering productivity, and the new era on the horizon. Cadence's Krunal Patel finds that the security of data transmission can be improved by integrating Ethernet with Internet Protocol Security (IPSec), which ... » read more

Synaptic transistor Researchers from Northwestern University, Boston College, and MIT developed a synaptic transistor that simultaneously processes and stores information similar to the human brain. The team said the transistor goes beyond simple machine learning tasks to categorize data and is capable of performing associative learning. The new device is stable at room temperatures. It als... » read more

Blog Review: Dec. 20


Siemens' Huw Geddes finds that the flexibility offered by the RISC-V ISA can introduce further verification and validation requirements to ensure that the combination of extensions and customization not just works but does not break anything else while delivering expected performance, plus looks at how processor trace can help. Cadence's Gustavo Araujo explains the various optimizations in t... » read more
