Is Your Voltage Drop Flow Obsolete?
Ansys Rethinks Dynamic Voltage Drop (DVD) From the Ground Up
Voltage drop is a critical issue that has become unmanageable with current methodologies used by most chip designers. The problem has intensified at advanced nodes as designers are trying to pack more transistor channels into smaller areas, increasing current density. Meanwhile, power supply currents flow through increasingly smaller wires with higher resistances, leading to significant voltage drops.
Power and heat dissipation have also become major concerns. Lowering the supply voltage is the most effective technique to reduce power consumption in high-performance designs with high operating frequencies. However, this leaves very little margin for voltage drops in the power distribution network (PDN), necessitating meticulous management of voltage drops. Read this article to understand dynamic voltage drop problems in modern chip designs and how Ansys SigmaDVD technology can be used to address this issue.
