An experiment to demonstrate the hierarchical effect is carried out by artificially setting a hierarchical design environment with a combination of several thousands of cells. Performance competitive with that without a hierarchical approach is obtained in the resultant areas and interconnect lengths. As ...
Association rule mining has been applied actively in order to discover the hidden factors in acute myocardial infarction. There has been minimal research r... WJ Kim,HC Shin - 《Icvc International Conference on Vlsi & Cad》 被引量: 1发表: 1997年 Automatic Identification Of Hierarchical Cells Ba...
The framework is based on elements. A top-down hierarchical processing element, e.g., that determines context before processing VLSI cells, limits peaks in temporary resource use. The top-down hierarchical processing adapts to the degree of design nesting by balancing flat processing techniques with...

The inverse layout tree concept is used to perform fully hierarchical DRC without any constraints on the use of overlapping or incomplete cells that are co... Nils Hedenstierna,Kjell,Jeppson 被引量: 14发表: 1989年 Layout device A layout device that reduces work. The layout device includes a ...
It maintains the simultaneous treatment of all cells over all global optimization steps, considering constraints which reflect the current dissection of the circuit. The methods have been applied to very complex designs and excellent results in terms of both quality and computation time have been ...
However, cell instance interaction can hardly be avoided since the designer can easily find a number if reasons why cells should be allowed to overlap. From the designers point of view complete release of any constraint is preferable. However, this freedom for the designer complicates design ...

A method of optimizing hierarchical very large scale integration (VLSI) design by use of cluster-based cell cloning. The method of the present invention provides improved yield or migration by reusing cells in order to reduce the number of unique instances of at least one of the reused cells....
