  • Patent number: 6363518
    Abstract: A computer-automated tool re-positions an instance relative to another instance along a given dimension. First, positions of both instances along the given dimension are determined. Then, a modified position is determined for one instance according to a convex function, which defines a global minimum solution between the initial instance positions.

  • Patent number: 5818726
    Abstract: A system and method for testing the placement of logic circuits on a regularly repeated array of integrated devices includes a base array memory, a basis memory, a floor plan memory, an array class memory, a logic cell index memory, a legal location index map memory, a legal location table memory and an engine. The system creates an array class for each type of device that is fabricated on the base array. The engine then tests each location of a basis of each array class for the legality of placing each logic cell of an associated group at that location. The engine then constructs a map of the array class, the legal location index map. Each entry on the map corresponds to a location in the array class, and each entry on the map contains a reference to a bit pattern. The engine also constructs a legal location table. The legal location table is a set of unique bit patterns that indicate the logic cells that may be placed at a location.

  • Patent number: 5481474
    Abstract: A computer-aided engineering (CAE) tool simulates physical floor-planning of electronic components to be placed and interconnected on both sides of a printed circuit board (PCB). Initially components are placed in a raw portion of the PCB, until an evaluator determines where to re-place selected components in refined portions on both sides of the PCB. The evaluation process is repeated until all components are selected from the raw portion and re-placed in a refined portion. During evaluation, a profile of the raw portion is generated, and the generated profile is searched for a location for placing each selected component.

  • Patent number: 5363313
    Abstract: Apparatus and methods for two-dimensional compaction of object collections defines an initial set of unrefined objects and an initial compaction direction. One by one, each unrefined object is taken from the unrefined object configuration and placed within a refined configuration. Both unrefined and refined configurations possess profiles along which the selected object is placed. Pruning rules select which locations to investigate more closely, by eliminating those positions that clearly do not provide compaction improvement. Various orientations and/or shapes of an object can be tried to improve the compaction or the group of objects. Once a best location for the object is found, the object is included in the refined object set, new unrefined and refined profiles are constructed, and a new unrefined object is selected to place. Once all unrefined objects have been selected and placed, the compaction process for the chosen direction has completed.
