UPF Power Domains And Boundaries


The Universal Power Format (UPF) plays a central role in mitigating dynamic and static power in the battle for low-power in advanced process technology. A higher process node is definitely attractive as more functionality integration is possible in a smaller die area at a lower cost. However, in reality, this comes at the cost of exponentially increasing leakage power. This is because the minim... » read more

Libraries: Standardization and Requirements For Power-Aware Dynamic Simulation


INTRODUCTION Multivoltage (MV) based power-aware (PA) design verification and implementation methodologies requires special power management attributes in libraries for standard, MV and Macro cells for two distinctive reason. The first aspect is to provide power and ground (also bias) supply or PG-pin information, which is mandatory for PA verification. The second reason is to provide a distin... » read more

Working With Custom Checkers In Dynamic Simulation Of Low Power Designs


Power-aware simulators can provide a wide range of automated assertions in the form of dynamic sequence checkers that cover every possible PA dynamic verification scenario. However, design specific PA verification complexities may arise from adoption of one or a multiple of power dissipation reduction techniques, from a multitude of design features — like UPF strategies — as well as from ta... » read more
