Auto Power Becoming Much More Complex

Rising electronics content in automobiles is putting increased focus on automotive power delivery networks (PDNs). Safety implications mean that thorough power design and verification, along with novel power isolation techniques, are needed at the vehicle level, involving both electrical and mechanical considerations. The electronic takeover can be measured by the percentage that electronic ... » read more

Blog Review: Nov. 7

Arm's Shidhartha Das looks into maximizing the benefits of power delivery networks and explains a non-intrusive technique using an on-chip digital storage oscilloscope that can directly sample the power-rails to probe potential runtime bugs due to power delivery weaknesses. Synopsys' Snigdha Dua argues that scrambling is one of the most important features introduced in HDMI 2.0 and takes a l... » read more

Tech Talk: Power Sign-Off

Calvin Chow, area technical manager at Ansys, talks about power sign-off for complex SoCs at advanced nodes, including early stage prototyping, the importance of context, accurate power modeling of sub-blocks, and simulation of power-delivery networks. [youtube vid=MN4TjZ3dHVk] » read more

FinFET-Based Designs: Power Sign-off Considerations

FinFET devices can operate at ultra-low sub-1V nominal supply voltage levels without impacting their delays. This allows for low power, higher performance designs needed for many of todays’ applications. These devices also have considerably higher drive strengths, allowing faster operating speeds. However, this can result in more localized di/dt current scenarios, and when coupled with more r... » read more
