Web6 de abr. de 2012 · Introduction. Writing power intent for a design using the IEEE 1801 Unified Power Format (UPF) is generally an easy and straight-forward task. If the design will be optimized in a flat fashion (e.g. the entire design is optimized top-down in a single session), then writing the power intent is fairly simple. Situations such as being too rigid … WebIn this paper, we present an efficient model for quick floorplanning in VLSI top-down hierarchical physical design flow using the Active-Logic Reduction Technology. The …
