Just added to the Cadence Resource Library for Allegro PCB SI is a whitepaper written by Advanced Layout Solutions. In this post, Chris Halford discusses how his company works to ensure the PCBs they design meet requirments for voltage and temperature stability. As Chris mentions, the challenge of managing power paths is complicated by the need to carve up power planes into swiss cheese like structres around high pin count BGA devices. We're pleased to hear of the successes Chris and his team have found navigating these challenges using Allegro PCB SI, and specifcally using the IR Drop feature available in all 16.x releases of the tool.
