摘要： A system, method, and software program for facilitating the assignment of cell specifications to a plurality of cells of a system design. The methods include generating a plurality of candidate cell specifications that meet the specification for the system design. In one embodiment, the method entails using information related to intra-range preference for cell specifications to generate a set of alternative system pareto-optimal solutions which define a boundary of a region of candidate cell specifications. In another embodiment, the method entails generating a substantially uniform set of candidate cell specifications using a prediction-based performance model, such as support vector regression model or cluster-weighted model, an optimizing algorithm such as conjugate-gradient or Markov Chain Monte Carlo Method, and a sample density model. The method may also include graphically displaying substantially uniformly distributed cell performance data and corresponding system performance data, and allowing a user to focus on regions-of-interest via a selectable range graphic feature.

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： To estimate a distribution of voltages or currents in the layers of a multi-layer circuit, an exemplary current flow in each layer is discretized into a number of current vector elements and at least one scalar charge element related to the charge associated with each current vector element. A first distribution of voltages induced in each circuit layer is determined from current vector elements in all of the circuit layers. A second distribution of voltages induced in each circuit layer is determined from the scalar charge elements in all of the circuit layers. For each circuit layer, the first and second distributions of voltages induced therein are combined to determine an actual distribution of voltages in the circuit layer.

摘要： In an automated integrated circuit design, if the performances of a layout of circuit devices are not within predetermined tolerances of performance specifications, at least one of the circuit devices is resized or repositioned and an updated value of a device parameter for each resized or repositioned circuit device is determined. A difference between the initial and updated value of each device parameter is then determined and each difference is combined with a ratio formed from changes in the value of one of the device parameters and changes in the value of one of the performances affected by the device parameter. The result of this combination is then combined with the initial value of the performance to determine an updated value therefor.
