How Sub-THz Will Impact the Future Of 6G
By Alejandro Escobar Calderon - 30 May, 2023 - Comments: 0

By Alejandro Escobar Calderon and Gerardo Orozco The world is more connected than ever before and, while this notion isn’t new, many of us fail to fully grasp at times the magnitude of connection growth speed. As of 2022, the world had around 13.2B IoT connections (Ericsson Mobile) with a YoY growth of 13%. Additionally, mobile network data traffic has doubled every two years since 2019. T... » read more

Week In Review: Design, Low Power
By Karen Heyman - 26 May, 2023 - Comments: 0

Cadence bought Pulsic, a U.K.-based developer of place-and-route tools for custom digital and analog. The acquisition follows a previous acquisition attempt by a Chinese firm in August 2022, which was blocked by the U.K. government. At the G7 Summit in Japan, IBM announced a 10-year, $100 million initiative with the University of Tokyo and the University of Chicago to develop a quantum-centr... » read more

A Highly Wasteful Industry
By Brian Bailey - 25 May, 2023 - Comments: 1

The systems industry as a whole is not concerned about power. I know that is a bold statement, but I believe it to be true. The semiconductor industry is mildly concerned, but only indirectly. They care about power because thermal issues are limiting the functionality they can squeeze onto a chip, or in a package. Some users, such as data center operators, claim to care about power because i... » read more

Chiplet Planning Kicks Into High Gear
By Ann Mutschler - 25 May, 2023 - Comments: 0

Chiplets are beginning to impact chip design, even though they are not yet mainstream and no commercial marketplace exists for this kind of hardened IP. There are ongoing discussions about silicon lifecycle management, the best way to characterize and connect these devices, and how to deal with such issues as uneven aging and thermal mismatch. In addition, a big effort is underway to improve... » read more

IP Becoming More Complex, More Costly
By Brian Bailey - 25 May, 2023 - Comments: 0

Success in the semiconductor intellectual property (IP) market requires more than a good bit of RTL. New advances mandate a complete design, implementation, and verification team, which limits the number of companies competing in this market. What constitutes an IP block has changed significantly since the concept was first introduced in the 1990s. What was initially just a piece of RTL (reg... » read more

Stitching Together A Multi-Layer PCB PDN
By Patrick Carrier - 25 May, 2023 - Comments: 0

A printed circuit board (PCB) is much like a complicated city, with a myriad of intertwined pathways for data signals and power. To meet the electric current needs of modern, high-powered integrated circuits (ICs), the power distribution network (PDN) usually consists of wide power planes on multiple layers to provide a low-resistance path for power delivery. These planes are stitched together ... » read more

Top500: Frontier Is Still On Top
By Barry Pangrle - 25 May, 2023 - Comments: 0

The latest versions of the Top500 and Green500 lists were just released on May 22, 2023. The last time that I wrote about the Green500, a Chinese machine, NRCPC’s Sunway TaihuLight, was sitting at the top of the Top500 list. It’s been a while since I last wrote about these lists and it’s interesting to look back at the leap in performance and energy efficiency over the past 7 years. ... » read more

The History Of CMOS
By Paul McLellan - 25 May, 2023 - Comments: 0

Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. NMOS Before CMOS, there was NMOS (also PMOS, but I have no direct experience with that). An NMOS gate consisted of a network of N-transistors between the output and Vss, and a resistor (actually a transistor with an implant) between the output and... » read more

An Ideal Always-Sensing Subsystem Architecture
By Paul Karazuba - 25 May, 2023 - Comments: 0

Always-sensing cameras are a relatively new method for users to interact with their smartphones, home appliances, and other consumer devices. Like always-listening audio-based Siri and Alexa, always-sensing cameras enable a seamless, more natural user experience. Through continuous sampling and analyzing visual data, always-sensing enables use cases such as: “Find a face” detection for... » read more
