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.

WebMetrics. Abstract: A description is given of the Kinden environment, which combines object-oriented modeling and model-based reasoning to capture, integrate, and manage VLSI design process attributes and hierarchies. Related work is briefly reviewed, and the modeling of the design process is discussed, focusing on the Kinden approach. raymond hess ann arbor https://gioiellicelientosrl.com
