Leaning Into The SoC Power Methodology


As inflation skyrockets and the price of everything increases seemingly by the hour, finding ways to trim time and costs are more valuable than ever. Lean manufacturing was introduced by the Toyota Motor Corporation almost 100 years ago, laying the framework for future generations of manufacturing and industrial settings. Lean manufacturing is a methodology that focuses on minimizing waste w... » read more

Emulation-Centric Power Analysis Of SoC Designs


Verification expert Lauro Rizzatti recently interviewed Jean-Marie Brunet, senior marketing director, Scalable Verification Solutions Division (SVSD), Siemens EDA, about the importance of accurate power estimation and optimization for system-on-chip (SoC) designs. What is the problem facing the semiconductor industry today regarding pre-silicon power estimation? The problem is the discrep... » read more

What’s Next For Emulation


Emulation is now the cornerstone of verification for advanced chip designs, but how emulation will evolve to meet future demands involving increasingly dense, complex, and heterogeneous architectures isn't entirely clear. EDA companies have been investing heavily in emulation, increasing capacity, boosting performance, and adding new capabilities. Now the big question is how else they can le... » read more

Bringing Scalable Power Integrity Analysis To Analog IC Designs


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

Know Your Own Power, Early And Accurately


By Taruna Reddy and Vin Liao Chip designers have always had to balance timing and area. Everyone wants a design as fast as possible and as compact as possible, but these two goals are usually in conflict. For the last couple of decades, minimal power consumption has been a third goal, often of equal importance. Some of the biggest drivers for the semiconductor industry are battery operated p... » read more

Chip-Package Co-Analysis Using Ansys RedHawk-CPA


Ansys RedHawk-CPA is an integrated chip–package co-analysis solution that enables quick and accurate modeling of the package layout for inclusion in on-chip power integrity simulations using Ansys RedHawk. With RedHawk-CPA a designer can perform static IR drop analysis and AC hotspot analysis of the package layout following RedHawk static and dynamic analyses respectively. To ensure a reliab... » read more

For AI Hardware, Power Optimization Starts With Software And Ends At Silicon


Artificial intelligence (AI) processing hardware has emerged as a critical piece of today’s tech innovation. AI hardware architecture is very symmetric with large arrays of up to thousands of processing elements (tiles), leading to billion+ gate designs and huge power consumption. For example, the Tesla auto-pilot software stack consumes 72W of power, while the neural network accelerator cons... » read more

Power Management Becomes Top Issue Everywhere


Power management is becoming a bigger challenge across a wide variety of applications, from consumer products such as televisions and set-top-boxes to large data centers, where the cost of cooling server racks to offset the impact of thermal dissipation can be enormous. Several years ago, low-power design was largely relegated to mobile devices that were dependent on a battery. Since then, i... » read more

Differential Power Analysis


Authors Paul Kocher, Joshua Jaffe, and Benjamin Jun Cryptosystem designers frequently assume that secrets will be manipulated in closed, reliable computing environments. Unfortunately, actual computers and microchips leak information about the operations they process. This paper examines specific methods for analyzing power consumption measurements to and secret keys from tamper resistant d... » read more
