The Evolution Of Digital Twins


Digital twins are starting to make inroads earlier in the chip design flow, allowing design teams to develop more effective models. But they also are adding new challenges in maintaining those models throughout a chip's lifecycle. Until a couple of years ago, few people in the semiconductor industry had even heard the term "digital twin." Then, suddenly, it was everywhere, causing confusion ... » read more

Preventing Line Change Disruptions With Digital Twins


During times of crisis, companies can struggle to meet the demand for everyday necessities. Companies need to increase uptime without risking equipment or product quality. During times of crisis, like the COVID-19 pandemic, manufacturing companies can struggle to meet the demand of everyday necessities. We’ve seen this happen in real-time with the shortages of personal protective equipm... » read more

Medical, Industrial & Aerospace IC Design Changes


Medical, industrial and aerospace chips are becoming much more complex as more intelligence is added into these devices, forcing design teams to begin leveraging tools and methodologies that typically have been used only at the leading-edge nodes for commercial applications. But as with automotive, the needs of these systems are changing quickly. In addition to strict quality, safety and sec... » read more

Making Sense Of EDA And Digital Twins


There is a new buzzword in town, “digital twins.” I have been using it for a while now in the context of system-on-chip (SoC) verification as well as a little more broadly when it comes to security issues for data in general. There are some differences in emphasis across different vertical domains, based on when they are used during the life cycle, which use models are desired and what scop... » read more

Digital Twins In Automotive


The term “digital twin” refers to a new principle that is gaining importance in the development of complex hardware/software systems. In general, it refers to a virtual representation of the real system. This model serves to simulate the functional interactions of the parts, saving time and money by avoiding unnecessary redesign cycles and enabling considerably better optimization of the ov... » read more

Combining Digital Twins And IoT In The Cloud


Engineers are tasked with the continuous improvement of the products, services and systems they design. The trouble is, once a product is out in the field, it’s hard to know how that design is performing — or being used. By coupling digital twin and internet of things (IoT) technology, engineers can get a better idea of a product’s real-world performance. As a reminder, digital twins a... » read more

Finding Hardware Trojans


John Hallman, product manager for trust and security at OneSpin Technologies, looks at how to identify hardware Trojans in a design, why IP from different vendors makes this more complicated, and how a digital twin can provide a reference point against which to measure if a design has been compromised. » read more

Making And Protecting Advanced Masks


Semiconductor Engineering sat down to discuss lithography and photomask trends with Bryan Kasprowicz, director of technology and strategy and a distinguished member of the technical staff at Photronics; Thomas Scheruebl, director of strategic business development and product strategy at Zeiss; Noriaki Nakayamada, senior technologist at NuFlare; and Aki Fujimura, chief executive of D2S. What fol... » read more

Are Digital Twins Something For EDA To Pursue?


‘Digital Twins’ are one of the new, fashionable key concepts for system developers, but do they fit with EDA? How many different types of engines do these twins run on – abstract simulation, signal-based RTL simulation, emulation, prototyping, actual silicon? What should the use models be called for digital twinning – like reproduction of bugs from silicon in emulation? Or optimizing th... » read more

Week in Review: IoT, Security, Auto


Internet of Things Smart-building technology is a factor in marketing new facilities to prospective tenants. The new Cambridge Crossing development in Cambridge, Mass., aspires to attract tech-oriented tenants much like nearby Kendall Square, this analysis notes. Philips has agreed to lease seven floors in Cambridge Crossing’s first office building, making that location its North American he... » read more
