New End Markets, More Demand For Complex Chips
By Ed Sperling - 16 May, 2022 - Comments: 0

Experts at the Table: Semiconductor Engineering sat down to discuss economic conditions and how that affects chip design with Anirudh Devgan, president and CEO of Cadence; Joseph Sawicki, executive vice president of Siemens EDA; Niels Faché, vice president and general manager at Keysight; Simon Segars, advisor at Arm; and Aki Fujimura, chairman and CEO of D2S. This discussion was held in front... » read more

DRAM Choices Becoming Central Design Considerations
By Ann Mutschler - 12 May, 2022 - Comments: 0

Chipmakers are paying much closer attention to various DRAM options as they grapple with what goes on-chip or into a package, elevating attached memory to a critical design element that can affect system performance, power, and cost. These are increasingly important issues to sort through with a number of tradeoffs, but the general consensus is that to reach the higher levels of performance ... » read more

The Challenge Of Optimizing Chip Architectures For Workloads
By Brian Bailey - 12 May, 2022 - Comments: 1

It isn't possible to optimize a workload running on a system just by looking at hardware or software separately. They need to be developed together and intricately intertwined, an engineering feat that also requires bridging two worlds with have a long history of operating independently. In the early days of computing, hardware and software were designed and built by completely separate team... » read more

Improving PPA With AI
By John Koon - 12 May, 2022 - Comments: 0

AI/ML/DL is starting to show up in EDA tools for a variety of steps in the semiconductor design flow, many of them aimed at improving performance, reducing power, and speeding time to market by catching errors that humans might overlook. It's unlikely that complex SoCs, or heterogeneous integration in advanced packages, ever will be perfect at first silicon. Still, the number of common error... » read more

Open RAN Phase 2
By Paul McLellan - 12 May, 2022 - Comments: 0

I first wrote about Open RAN in my post Fourth 4G Network Goes Live in Japan. Open RAN is a program driven by a group of European operators to build specifications for common architecture instead of getting "locked into" the closed architectures sold by the big base-station vendors such as Nokia, Samsung, and Ericsson. It is analogous to what servers went through over the last few decades, m... » read more

Software-Defined Cars
By Ann Mutschler - 11 May, 2022 - Comments: 0

Automotive architectures are becoming increasingly software-driven, a shift that simplifies upgrades and makes it easier to add new features into vehicles. All of this is enabled by the increasing digitalization of automotive functions and features, shifting from mechanical to electrical design, and increasingly from analog to digital data. That enables OEMs to add or up-sell features years ... » read more

Blog Review: May 11
By Jesse Allen - 11 May, 2022 - Comments: 0

Ansys' Vidyu Challa checks out how to identify the most important battery metrics for a particular application and trade these off against others with a focus on the important considerations when selecting the right battery for a consumer application, such as rechargeability, energy density, power density, shelf life, safety, form factor, cost, and flexibility. Cadence's Shyam Sharma points ... » read more

Week In Review: Design, Low Power
By Jesse Allen - 06 May, 2022 - Comments: 0

Rambus will acquire Hardent, a provider of design services and IP. Rambus said Hardent's silicon design, verification, compression, and Error Correction Code (ECC) expertise will provide key resources for the Rambus CXL Memory Interconnect Initiative. “Driven by the demands of advanced workloads like AI/ML and the move to disaggregated data center architectures, industry momentum for CXL-base... » read more

Building Security Into ICs From The Ground Up
By John Koon - 05 May, 2022 - Comments: 0

Cyberattacks are becoming more frequent and more sophisticated, but they also are starting to compromise platforms that until recently were considered unbreakable. Consider blockchains, for example, which were developed as secure, distributed ledger platforms. All of them must be updated with the same data for a transaction to proceed. But earlier this year a blockchain bridge platform calle... » read more

Simulate Rotor Hub Vortex Shedding In Helicopters
By Veena Parthan - 05 May, 2022 - Comments: 0

Although helicopter aerodynamics involves the same forces that arise in airplane aerodynamics, these forces occur differently due to fluid flow dynamics across the aircraft. Helicopters take advantage of the free stream flow along a rotor blade to produce lift and thrust. In rotating systems, the rotor hub clasps the blades and connects them to the main shaft of the system. The rotor in a h... » read more
