    摘要: A visualization and data mining technique can be utilized to facilitate analysis of generated sets of design points for an integrated circuit to enable easy and fast understanding of important properties of generated designs. The use of the visualization and data mining technique significantly reduces the time needed for analysis of design space and decision on which design point to choose for implementing into a circuit design.

    摘要: Systems and methods are disclosed for contextual analysis and segmentation of information objects. According to one implementation, information objects, such as web pages and user profiles, may be analyzed to identify key terms. These key terms may be included in a contextual representation of an information object. By comparing the contextual representations of a plurality of information objects, one or more contextual segments (i.e., categories of information objects) may be created. Each contextual segment may also be associated with its own contextual representation. Once a contextual segment has been created, information objects may be assigned to the contextual segment. These contextual segments may be used to deliver targeted advertising, for example.

    摘要: In a method of determining the existence of one or more conflicts in the placement or configuration of circuit objects defining a circuit, a number of constraints is defined, each of which imposes at least one limitation on at least one circuit object. A number of constraint families is then defined, each of which includes a subset of interrelated constraints. For each of a subset of the constraint families, a determination is made if a conflict exists between the constraints thereof. If not, pairs of constraint families are defined from the plurality constraint families. For each of a subset of the pairs of constraint families, a determination is made if a conflict exists between the constraints thereof. If not, the circuit objects defining the circuit are laid out subject to the constraints.

    摘要: The invention is a method of placement of components and networks (nets), utilized for interconnecting the components, of a circuit layout. The method includes forming for electrical devices, pads (or lands) and networks (nets) of a circuit layout a listing of the positions thereof with respect to one another, connections therebetween and the orientation of each net or subnet thereof in the circuit layout. The thus formed list is processed subject to at least one objective regarding the size of the circuit layout, whereupon a placement of the electrical devices and the pads is determined simultaneously with the placement of the networks.

    摘要: Each circuit simulation performed on unique layout of circuit devices generates a design point (DP) that includes device variable values and performance goal values. Circuit models for at least one performance goal are determined as a function of a first subset of the DPs. A performance goal value is determined for each circuit model based on the device variable values obtained from a second subset of the DPs. Errors are determined between the thus determined value of each performance goal and values of the corresponding performance goals obtained from the second subset of the DPs. Input values of device variables are processed with at least one of the circuit models having the smallest error associated therewith to determine therefor a performance goal value. A layout of the circuit devices is generated based on the input device variable values associated with at least one of the thus determined performance goals.
