The Rising Price Of Power In Chips
By Ed Sperling - 14 Mar, 2024 - Comments: 0

Power is everything when it comes to processing and storing data, and much of it isn't good. Power-related issues, particularly heat, dominate chip and system designs today, and those issues are widening and multiplying. Transistor density has reached a point where these tiny digital switches are generating more heat than can be removed through traditional means. That may sound manageable e... » read more

Unknowns Driving Up The Cost Of Auto IC Reliability
By Ed Sperling - 08 Feb, 2022 - Comments: 2

Automotive chipmakers are considering a variety of options to improve the reliability of ICs used for everything from sensors to artificial intelligence. But collectively they could boost the number of process steps, increase the time spent in manufacturing and packaging, and stir up concerns about the amount of data that needs to be collected, shared, and stored. Accounting for advanced pro... » read more

Automation And Correct By Construction Will Empower 3D-IC Adoption
By Youngsoo Lee - 27 Jun, 2019 - Comments: 0

When research on 3D ICs was in full swing around 2009, I had been researching on how through-silicon-via (TSV) was related to thermal in a semiconductor chip-making company, and it seemed logical that 3D ICs would become mainstream. However, during the past 10 years, use of 3D stacked die has been applied to only a few applications, such as memory or image sensors, and the 2.5D solution using i... » read more

Wrestling With High-Speed SerDes
By Ann Mutschler - 19 Jun, 2019 - Comments: 2

SerDes has emerged as the primary solution in chips where there is a need for fast data movement and limited I/O, but this technology is becoming significantly more challenging to work with as speeds continue to rise to offset the massive increase in data. A Serializer/Deserializer is used to convert parallel data into serial data, allowing designers to speed up data communication without h... » read more

Raising The Abstraction Level For Power
By Brian Bailey - 09 May, 2019 - Comments: 0

Power-aware design is still a relatively new concern for many semiconductor products, and since inception it has changed several times and in different ways. Initially people were concerned about peak power. Today, they care about peak, total energy, thermal and other effects. The industry has tried several abstractions ranging from system-level analysis, which promised to swamp implementati... » read more

The Growing Materials Challenge
By Katherine Derbyshire - 11 Jun, 2018 - Comments: 0

By Katherine Derbyshire & Ed Sperling Materials have emerged as a growing challenge across the semiconductor supply chain, as chips continue to scale, or as they are utilized in new devices such as sensors for AI or machine learning systems. Engineered materials are no longer optional at advanced nodes. They are now a requirement, and the amount of new material content in chips contin... » read more

Closing The Power Integrity Gap
By Ann Mutschler - 19 Oct, 2016 - Comments: 0

Voltage drop has always been a significant challenge. As far back as 130nm, specialist tools were being used to ensure that enough local decoupling capacitance (decap) cells were inserted in addition to larger decaps implemented around the SoC. But advanced nodes are complicating matters and further increasing complexity. These technological challenges, which underlie the power, performance ... » read more

Power Breaks Everything
By Ed Sperling - 15 Jul, 2015 - Comments: 2

The emphasis on lowering power in everything from wearable electronics to data centers is turning into a perfect storm for the semiconductor ecosystem. Existing methodologies need to be fixed, techniques need to be improved, and expectations need to be adjusted. And even then the problems won't go away. In the past, most issues involving power—notably current leakage, physical effects such... » read more

How Switching Activity Impacts A Design’s Power And Reliability
By Chris Ortiz - 14 May, 2015 - Comments: 0

Electronics continue to gain presence in both familiar and unfamiliar areas of our lives. Electronics is a common thread among the cars we drive, the computers we use, the mobile phones and wearable devices that we rely on. We appreciate the information and convenience that Fitbits and other products such as coffee makers, credit cards and building security cards provide us. And we are beginni... » read more

IP Design Essentials For Power Integrity
By Annapoorna Krishnaswamy - 06 Nov, 2014 - Comments: 0

Smart connectivity is the new mantra of today – the ability to connect to anything, anywhere and at any time. With such technology enablement, low power is not a choice but an expectation. Whether it is a connected device, or a system that is part of the infrastructure, they are driven to integrate various functionality such as high speed computing, high-speed memory, memory interfaces, radio... » read more
