Blog Review: July 17


Mentor's John McMillan takes a look at the three general classes that have been established by IPC-2221B to reflect progressive increases in sophistication, functional performance requirements, and testing/inspection frequency for PCBs. Synopsys' Dinesh Siwal and Thenmozhy Kaliyamurthy point out the new features and improvements in DisplayPort 2.0, including greater speeds, better power effi... » read more

Power/Performance Bits: July 15


Liquefied gas electrolyte Researchers at UC San Diego, U.S. Army Research Laboratory, and South 8 Technologies developed an electrolyte that could enable the replacement of the graphite anode in lithium-ion batteries with lithium-metal. Such a change would increase energy density 50% at the cell level, making for lighter batteries with more capacity. However, lithium-metal anodes are not compa... » read more

Week In Review: Design, Low Power


Synopsys unveiled the latest version of its IC Compiler II place-and-route system, adding a common physical optimization infrastructure, new arc-based unified concurrent clock-and-data (CCD) optimization, physically-aware logic re-synthesis, and dynamic voltage drop-driven power shaping. Additionally, next-generation distributed parallelization, intelligent scenario management, efficient infras... » read more

Power/Performance Bits: July 10


Wearable heart monitoring Researchers at the University of Texas at Austin developed a lightweight, stretchy heart monitoring patch that can be worn externally. Along with being easy to wear, the graphene-based 'e-tattoo' is more accurate than existing electrocardiograph machines, according to the team. The e-tattoo measures cardiac health using both electrocardiograph and seismocardiograph... » read more

Synopsys' Eric Huang takes a look at how backward compatibility with USB 2.0 is provided when the IO voltages of new nodes can't support 3.3V signaling and how eUSB2 can boost the signal and provide support for external or legacy peripherals. In a video, Mentor Colin Walls explains endianness in embedded systems with a look at what it is, when it matters, and how to accommodate it in code. ... » read more

Si2's Unified Power Model has been approved as IEEE 2416-2019, a new Standard for Power Modeling to Enable System Level Analysis, which complements UPF/IEEE 1801-2018. UPM/IEEE 2416-2019 provides a set of power modeling semantics enabling system designers to model entire systems with flexibility. It supports power modeling from abstract design description to gate level implementation, providing... » read more

Cadence's Paul McLellan digs into 5G with a two-part post explaining the basics of the technology, what makes it so different from 4G, and the challenges ahead including the limitations of mmWave. Synopsys' Vikramjeet Bamel and Pankaj Sharma note the features that make GDDR6 a dominant memory in the high performance segment and allowing it to expand beyond graphics to automotive, AI, and AR/... » read more

Power/Performance Bits: July 3


2D straintronics Researchers at the University of Rochester and Xi’an Jiaotong University dug into how 2D materials behave when stretched to push the boundaries of what they can do. "We're opening up a new direction of study," says Stephen Wu, assistant professor of electrical and computer engineering and physics at Rochester. "There's a huge number of 2D materials with different properti... » read more

VESA published the DisplayPort 2.0 standard, which allows for a max payload of 77.37 Gbps, a 3X increase in data bandwidth performance compared to DisplayPort 1.4a. The latest release also includes capabilities to address beyond 8K resolutions, higher refresh rates and HDR support at higher resolutions, multiple display configurations, and support for 4K-and-beyond VR resolutions. It is backwar... » read more

Blog Review: June 26


Arm's Krish Nathella and Dam Sunwoo dig into research to make a practical implementation of a temporal data prefetcher that overcomes the huge on- and off-chip storage and traffic overheads usually associated with them. Cadence's Paul McLellan notes that while concerns about uncover bias in computer vision algorithms usually focus on people, a team at Facebook found that object recognition t... » read more
