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.

Method and system for layout and schematic generation for heterogeneous

A programmable gate array includes test subsystems for testing various functional subsystems of the programmable gate array. A sequence of test methods, employing the test subsystems, test the functionality of the programmable gate array, taking into account the interdependencies of the various subsystems and accordingly enabling fault isolation therein.

Testable programmable gate array and associated LSSD/deterministic test

A memory system having split logical bit lines and interleaved pre-charge/access cycles is provided. A bit line access circuit supports multiple conductors per logical bit line and pre-charges the conductors before access cycles thereto. The access cycles for one logical bit line are performed simultaneous with the pre-charge cycles for another logical bit line by the access circuit. Virtual reading is provided for eliminated memory cells. The memory system can be used in a programmable gate array having memory cells distributed throughout for programming respective programmable resources.
