Controlling Leakage Power


IC designers face a significant challenge in managing leakage power - a phenomenon that can profoundly impact your device's power, performance, area (PPA), and overall reliability. Leakage can occur in various ways, from parasitic leakage to analog gate leakage or digital gate leakage, and you must address these issues with great care, as even subtle circuit changes can lead to reliability prob... » read more

Vision Language Models Come Rushing In


Just when you thought the pace of change of AI models couldn’t get any faster, it accelerates yet again. In the popular news media, the introduction of DeepSeek in January 2025 created a moment that captured headlines in every newspaper and website heralding comparisons to the Sputnik moment of 1957. But rapid change is also happening in many quarters that are hidden from view of the Chat-App... » read more

ADAS Adds Complexity To Automotive Sensor Fusion


Sensor fusion is becoming increasingly popular and more complex in automotive designs, integrating multiple types of sensors into a single chip or package and intelligently routing data to wherever it is needed. The primary goal is to bring together information from cameras, radar, lidar, and other sensors in order to provide a detailed view of what's happening inside and outside of a vehicl... » read more
