Cloud library characterization; HDMI reduced blanking; hot quantum computing; browsing trace files.


Siemens EDA’s Wei-Lii Tan considers the tradeoffs when running library characterization in the cloud and how to think about running CPUs in parallel, the cost of throughput, and runtime reductions.

A Synopsys writer checks out the reduced blanking feature in HDMI 2.1, which can help reduce the transmission rate while keeping the resolution and refresh rate intact for higher resolution displays at low power.

Cadence’s Paul McLellan learns about ‘hot’ quantum computing from Jason Lynch, COO of Equal1, which has developed a quantum processor running at 3.7K and based on a commercially available CMOS process, plus challenges with decoherence and the startup’s next steps.

Arm’s Simon Tatham introduces an open-source code base for analyzing and browsing trace files in Tarmac trace format top make it easier to get a look at exactly how a CPU is behaving.

The ESD Alliance’s Bob Smith chats with Jean-Marie Brunet of Siemens EDA about the challenges in verifying increasingly complex SoCs and the opportunities for hardware-assisted verification to integrate hardware and software earlier in the process.

Memory analyst Jim Handy explains why migrating NAND flash to the next number of bits as soon as possible isn’t necessarily an optimal choice, with diminishing cost advantages and challenges in endurance and error correction.

Ansys’ Matt Commens introduces new meshing technology in the company’s high-frequency electromagnetic simulation software that uses local knowledge of the geometry to perform locally optimized meshing techniques for those geometries.

Nvidia’s Adam Grzywaczewski notes that while great progress has been made in natural language processing for a few languages, efforts are needed to expand it to other common languages such as Hindi, Arabic, and Spanish where NLP performance is poor.
