Revving Up SiC And GaN
By Ann Mutschler - 13 Dec, 2021 - Comments: 0

Silicon carbide (SiC) and gallium nitride (GaN) are becoming more popular for power electronics, particularly in automotive applications, driving down costs as volumes scale up and increasing the demand for better tools to design, verify, and test these wide-bandgap devices. Both SiC and GaN are proving essential in areas such as battery management in electric vehicles. They can handle much ... » read more

Will Markets For ML Models Materialize?
By Bryon Moyer - 02 Dec, 2021 - Comments: 0

Developers are spending increasing amounts of time and effort in creating machine-learning (ML) models for use in a wide variety of applications. While this will continue as the market matures, at some point some of these efforts might be seen as reinventing models over and over. Will developers of successful models ever have a marketplace in which they can sell those models as IP to other d... » read more

What’s Missing For Designing Chips At The System Level
By Ed Sperling - 01 Nov, 2021 - Comments: 0

Semiconductor Engineering sat down to talk about design challenges in advanced packages and nodes with John Lee, vice president and general manager for semiconductors at Ansys; Shankar Krishnamoorthy, general manager of Synopsys' Design Group; Simon Burke, distinguished engineer at Xilinx; and Andrew Kahng, professor of CSE and ECE at UC San Diego. This discussion was held at the Ansys IDEAS co... » read more

Analyzing Electro-Photonic Systems
By Brian Bailey - 30 Aug, 2021 - Comments: 1

The design and analysis of electro-optical systems is pushing tools into the complex multi-physics domain, making it challenging to create models that execute at reasonable cost — especially when they include thermal impacts. The lack of models and standards also is slowing the progression of the technology. Still the advantages are worth it to those willing to make the investment. Trad... » read more

Choosing The Right Model Fidelity For Your Digital Twin
By Frank Schirrmeister - 29 Jul, 2021 - Comments: 0

The EDA industry has advanced by leaps and bounds with innovation. Every time we approach a new technology node, many algorithms have to be re-imagined. As the late Jim Ready often pointed out to me, compared to the world of software development, these semiconductor technology changes are the hardware equivalent to what Fred Brooks, in his seminal article “No Silver Bullet—Essence and Accid... » read more

‘Hug The Debug’ – Before It’s Too Late
By Sumit Vishwakarma - 01 Jul, 2021 - Comments: 0

Though the term “shift-left” originated in the software industry, its importance is often cited in the hardware (semiconductor) industry where the end-product (chip) costs are skyrocketing. The increase in cost is driven by a global chip shortage, especially in the automotive industry. Manufacturing a robust chip is a long, iterative process that may require many re-spins. Shift-left refers... » read more

Process Model Calibration: The Key To Building Predictive And Accurate 3D Process Models
By Coventor - 16 Jun, 2021 - Comments: 0

The semiconductor industry has always faced challenges caused by device scaling, architecture evolution, and process complexity and integration. These challenges are coupled with a need to provide new technology to the market quickly. In the initial stages of semiconductor technology development, innovative process flow schemes must be tested using silicon test wafers. These wafer tests are len... » read more

Using Model-Based Systems Engineering To Design Complex Systems
By Anthony Dawson - 10 Jun, 2021 - Comments: 0

By Anthony Dawson and Jane Trenaman The benefits of using simulation early and often in the product development process are clear. You can verify requirements and begin studying and exploring design alternatives before prototyping and investing time in designs that ultimately won’t meet requirements. What may not be clear is how to integrate all the simulation tools that different engineer... » read more

Do We Have An IC Model Crisis?
By Brian Bailey - 27 May, 2021 - Comments: 0

Models are critical for IC design. Without them, it's impossible to perform analysis, which in turn limits optimizations. Those optimizations are especially important as semiconductors become more heterogenous, more customized, and as they are integrated into larger systems, creating a need for higher-accuracy models that require massive compute power to develop. But those factors, and other... » read more

Customized Micro-Benchmarks For HW/SW Performance
By Ed Sperling - 23 Mar, 2021 - Comments: 0

Raw performance used to be the main focus of benchmarks, but they may have outlived their usefulness for many applications. Dana McCarty, vice president of sales and marketing for AI Inference Products at Flex Logix, talks about why companies need to develop and utilize their own specific models to accurately gauge hardware and software performance, which can be slowed by bottlenecks in I/O and... » read more
