Power Issues Causing More Respins At 7nm And Below
By Brian Bailey - 26 Jan, 2023 - Comments: 0

Power consumption has been a major design consideration for some time, but it is far from being a solved issue. In fact, an increasing number of designs have a plethora of power-related problems, and those problems are getting worse in new chip designs. Many designs today are power-limited — or perhaps more accurately stated, thermal-limited. A chip only can consume as much power as it is ... » read more

Taking Power Much More Seriously
By Brian Bailey - 10 Nov, 2022 - Comments: 0

An increasing number of electronic systems are becoming limited by thermal issues, and the only way to solve them is by elevating energy consumption to a primary design concern rather than a last-minute optimization technique. The optimization of any system involves a complex balance of static and dynamic techniques. The goal is to achieve maximum functionality and performance in the smalles... » read more

A Power-First Approach
By Brian Bailey - 27 Oct, 2022 - Comments: 6

It is becoming evidently clear that heat will be the limiter for the future of semiconductors. Already, large percentages of a chip are dark at any time, because if everything operated at the same time the amount of heat generated would exceed the ability of the chip and package to dissipate that energy. If we now start to contemplate stacking dies, where the ability to extract heat remains con... » read more

Adaptive Clocking: Minding Your P-States And C-States
By Aakash Jani - 23 Jun, 2022 - Comments: 0

Larger processor arrays are here to stay for AI and cloud applications. For example, Ampere offers a 128-core behemoth for hyperscalers (mainly Oracle), while Esperanto integrates almost 10x more cores for AI workloads. However, power management becomes increasingly important with these arrays, and system designers need to balance dynamic power with system latency. As we march year over year, t... » read more

Zero Dark Silicon
By Ed Sperling - 09 May, 2022 - Comments: 0

Planning for AI requires an understanding of how much data needs to be processed and how quickly that needs to happen. Nick Ni, senior director of data center AI and compute markets at AMD, talks with Semiconductor Engineering about data bubbles and domain-specific designs, why dark silicon is no longer as useful as in the past, and how to optimize power and performance in both the data center ... » read more

Arm’s Input Qualification Methodology Using PowerPro
By Siemens EDA - 27 Apr, 2022 - Comments: 0

This white paper proposes a new automated input qualification methodology that Arm developed using Siemens EDA’s PowerPro software portfolio that performs various data integrity checks at the IC design build and prototype stage. This methodology ensures in quicker iterations that input data are high fidelity, leading to a well correlated power numbers. Should multiple iterations be necessary,... » read more

Thermal Management Implications For Heterogeneous Integrated Packaging
By Cameron Nelson - 17 Feb, 2022 - Comments: 1

As the semiconductor industry reaches lower process nodes, silicon designers struggle to have Moore's Law produce the results achieved in earlier generations. Increasing the die size in a monolithic system on chip (SoC) designs is no longer economically viable. The breakdown of monolithic SoCs into specialized chips, referred to as chiplets, presents significant benefits in terms of cost, yield... » read more

Batteries Take Center Stage
By Heidi Elliott - 27 Dec, 2021 - Comments: 0

For any mobile electronic device, the biggest limiting factors are the size, age, type, and utilization of the batteries. Battery technology is improving on multiple fronts. The batteries themselves are becoming more efficient. They are storing more energy per unit of area, and work is underway to provide faster charging and to increase the percentage of that energy that can be used, as well... » read more

Challenges With Stacking Memory On Logic
By Ed Sperling - 22 Dec, 2021 - Comments: 1

Experts at the Table: Semiconductor Engineering sat down to discuss the changes in design tools and methodologies needed for 3D-ICs, with Sooyong Kim, director and product specialist for 3D-IC at Ansys; Kenneth Larsen, product marketing director at Synopsys; Tony Mastroianni, advanced packaging solutions director at Siemens EDA; and Vinay Patwardhan, product management group director at Cadence... » read more

Bringing Scalable Power Integrity Analysis To Analog IC Designs
By Joe Davis - 14 Oct, 2021 - Comments: 0

Power integrity is a broad term in integrated circuit (IC) design and verification. However, when IC engineers are working through design signoff, power integrity analysis focuses on three specific aspects of a design: Power: Verify the chip design as implemented provides the total predicted power under different operating modes. Performance: Find and eliminate performance issues affect... » read more
