Dynamic Peak Power As A Proxy For DVD? Really?

Dynamic-voltage-drop (DVD) concerns have grown substantially at the 10nm and 7nm silicon process nodes. DVD refers to the transient voltage drop that a local power grid on a chip might experience if there is a rapid change in current. That drop can act like a “stall,” hurting performance until the grid recovers. Beefing up the power grid metal might seem to be the obvious fix, but, at th... » read more
