Getting Rid Of Heat In Chips


Power consumed by semiconductors creates heat, which must be removed from the device, but how to do this efficiently is a growing challenge. Heat is the waste product of semiconductors. It is produced when power is dissipated in devices and along wires. Power is consumed when devices switch, meaning that it is dependent upon activity, and that power is constantly being wasted by imperfect de... » read more

Power Methodology For Estimation And Optimization In The ASIC/SoC Flow


In this white paper, we’ll review the many steps of today’s common ASIC/SoC power methodologies and tool flows. We’ll then propose ways you can further optimize your power methodology to more quickly achieve your PPW goals. Please note, while we acknowledge that energy consumption in digital CMOS logic is a combination of dynamic power and leakage, to keep this white paper to a digestible... » read more

PPA(V): Performance-Per-Watt Optimization With Variable Operating Voltage


Performance-per-watt has emerged as one of the highest priorities in design quality, leading to a shift in technology focus and design power optimization methodologies. Variable operating voltage possess high potential in optimizing performance-per-watt results but requires a signoff accurate and efficient methodology to explore. Synopsys Fusion Design Platform, uniquely built on a singular RTL... » read more

Maximizing Value Post-Moore’s Law


When Moore's Law was in full swing, almost every market segment considered moving to the next available node as a primary way to maximize value. But today, each major market segment is looking at different strategies that are more closely aligned with its individual needs. This diversity will end up causing both pain and opportunities in the supply chain. Chip developers must do more with a ... » read more

Power Markets


There has been an ongoing discussion in the industry about the importance of power and performance and which is more important. I submit that the real question is: How much performance can be squeezed out of the power budget for any given market segment? Figure 1. Processor Market Segment Power Budgets Figure 1 shows a rough breakdown of the different market segments for processors, alo... » read more

The Power Game


By Ann Steffora Mutschler Semiconductor engineering teams always have focused on stepping up performance in new designs, but in the mobile, GPU and tablet markets they’re finding that maintaining the balance between higher performance and the same or lower power is increasingly onerous. The reason: Extreme gaming applications can create scenario files that cause dynamic power consumpt... » read more
