The Many Flavors Of UPF: Which Is Right For Your Design?

Energy efficient electronic systems require sophisticated power management architectures that present difficult low-power verification challenges. Accellera introduced the Unified Power Format (UPF) standard in 2007 to help engineers deal with these complex issues. To keep pace with the growing complexity of low-power designs, the UPF standard has itself continued to evolve through the relea... » read more

Three Steps To Faster Low Power Coverage Using UPF 3.0 Information Models

Controlling power has its costs. The added power elements and their interactions make verification of low-power designs much more difficult and the engineer’s job overwhelmingly complex and tedious. Early versions of the Unified Power Format (UPF) provided some relief, but lacked provisions for a standardized methodology for low-power coverage. Ad hoc approaches are error prone and highly ... » read more

Seeing Is Believing: Visualizing Full Coverage Closure In Low-Power Designs

By Madhur Bhargava and Durgesh Prasad Lowering the power consumption and leakage in SoCs and other electrical designs has become a paramount concern in recent years. The reasons for this are many and well understood. The structures and techniques we use to accomplish this have made verification of so called low-power designs more complex and difficult than it is for designs where power usage... » read more
