Electrical noise is a consideration that engineers think, talk, worry, sometimes obsess about, and deal with nearly all the time, with few exceptions. In many applications, it is the limiting factor on ultimate achievable system performance. If it were not for the existence of noise, many design situations would be far, far easier. Noise is […]

How IoT and mixed-signal designs will drive SiP tech in 2016
By Ian Dennison As the Internet of Things (IoT) becomes an increasingly competitive market, we should, in 2016, expect new package and board technologies to provide much of the innovation needed for successful IoT products. Since IoT products are driven by the need for the smallest form factor (think wearables) and ultra-low power (for longer […]
Low-power sensor fusion platform seamlessly integrates into wearables
Cadence Design Systems, Inc. (NASDAQ: CDNS) and CyweeMotion Ltd., today announced that CyweeMotion’s Sensor Fusion Hub™ software has been optimized for Cadence Tensilica Fusion digital signal processors (DSPs). This solution delivers a fully optimized, low-power sensor fusion platform for seamless integration into mobile or wearable devices. The Sensor Fusion Hub technology from CyweeMotion is sensor […]
Techniques to speed up SoC RTL and physical synthesis
David Stratman and Vinay Patwardhan, Cadence In the more complex world of today’s SoCs, you’re integrating a large number of third-party IP blocks with your own highly tuned RTL, while aggressively pushing frequency in the face of lower power requirements and area budgets. You also want to ensure a reliable handoff to place and route […]
