A method and system for defining, placing and routing kernels for a family of integrated circuits is provided. The integrated circuits are defined using repeatable row and column circuit types. Kernels are defined by the intersections of the row and column circuit types in the array. The kernels are placed and routed automatically for each member of the family of integrated circuit arrays, each member being generally characterized by a different size, i.e., a different number of repeatable row or column circuit types.
[ What is claimed is:] [1.] An architecture for a family of differently sized programmable arrays, each member of the family having a plurality of logic cells and support circuitry therein, the logic cells being arranged in four sections, the support circuitry being generally distributed throughout a cruciform-shaped region generally centered in the array which defines the four sections of logic cells therein, such that the length of the arms of the cruciform and the sizes of the sections can be together varied to produce the differently sized members of...
