Advancing Signaling Rates To 64 GT/s With PCI Express 6.0


From the introduction of PCI Express 3.0 (PCIe 3.0) in 2010 onward, each new generation of the standard has offered double the signaling rate of its predecessor. PCIe 3.0 saw a significant change to the protocol with the move from 8b/10b to highly efficient 128b/130b encoding. The PCIe 6.0 specification, now officially released, doubles the signaling rate to 64 gigatransfers per second (GT/s) a... » read more

SuperGrid Institute Responds to Energy and Climate Demands


Researchers and developers at SuperGrid Institute use Ansys electronics software solutions to perform studies on power converters, critical links in the chain between electric generators and consumers, for their clients. Fig. 1: Medium-voltage DC grid power supply topology. As an independent research and innovation institute based in France, SuperGrid Institute is dedicated to developin... » read more

CES 2022: In Person But Not Many People


CES was and is officially hybrid, with some events on-site in Las Vegas and some online. But many of the large exhibitors pulled out of attending in person (including Cadence, although we might be a big exhibitor at DAC but at CES we are tiny). A lot of the press seems to have stayed away in-person too. To be honest, a lot of the press has been gradually staying away for years since so much is ... » read more

Continuous Integration For Digital Design


By Christian Skubich and Nico Peter In 2001, the Manifesto for Agile Software Development [1] laid the foundation for many modern software development processes. Today, 20 years later, agile methods are in widespread use in numerous domains. Out of the participants in the study Status Quo (Scaled) Agile 2020 [2], only 9% still relied on classic project management methods. One core element... » read more

Scaling DDR5 RDIMMs To 5600 MT/s


Looking forward to 2022, the first of the DDR5-based servers will hit the market with RDIMMs running at 4800 megatransfers per second (MT/s). This is a 50% increase in data rate over top-end 3200 MT/s DDR4 RDIMMs in current high-performance servers. DDR5 memory incorporates a number of innovations, such as Decision Feedback Equalization (DFE), and a new DIMM architecture which enable that speed... » read more

Choose The Right Sensors For Autonomous Vehicles


When the world’s first “motorwagen” was introduced in 1885, the notion that a car would one day drive itself was laughable. Today, assisted and autonomous vehicles are the reality of an age where digital sensors can outperform human ability to perceive motion, distance, and speed. When used together, sensor technologies including camera, lidar, radar, and ultrasonic give vehicles one... » read more

The Future Of Smart Cameras Is 64-Bit Processing


The future of smart camera technology brings with it profound transformations in the way we interact with each other and the world around us. From smart cities that are safer and more efficient to rainforests that are monitored for illegal logging, the increasing need for advanced vision technology is growing. Diverse and complex use cases leveraging artificial intelligence (AI) and machine lea... » read more

Moving From AMBA ACE to CHI For Coherency


Introduced back in 2011, ACE (AXI Coherency Extensions) grew from the existing AXI protocol to satisfy the cache coherency maintenance demands of SoCs with multi core processors and shared caches in smart phones, mobile computers, and servers. It added new channels for cache communication, extra signals to allow new transaction for coherency support, and five state model for caches. AXI + A... » read more

Run Realistic Software For Full Chip Power Signoff


In the real world, the demand for AI chips is driving the trend towards bigger, smarter, and faster SoC designs. Consequently, low-power design, analysis, verification, and power signoff challenges are not getting any easier as chip designs deploy increasingly smaller geometries that dissipate more and more power. Despite this dilemma, the quest for further power reductions continues apace. ... » read more

Shifting Left In P&R With In-Design Signoff Fill For Faster And More Accurate Tapeouts


Place and route (P&R) engineers are always on the lookout for ways to optimize their design flows to ensure designs meet their design power, performance, and area (PPA) goals while also hitting tapeout deadlines. The introduction of the Calibre RealTime Digital interface made Calibre nmDRC and Calibre nmDRC Recon design rule checking (DRC) verification available during the P&R process t... » read more
