Structures for a configuration and self-configuration of WSI systems with a low degree of regularity

For WSI (wafer scale integration) systems with a low degree of regularity, a design strategy is investigated which features a self-configuration. Redundant arrangements of modules as well as implementations of subsidiary circuitry are presented. They provide a multiple defect tolerance even for central circuitry such as system control, test, and configuration circuitry. The components are implemented in a WSI system ( approximately 16 cm/sup 2/) which is still under production. Due to the modular nature of these components, they may be applied to other complex redundant systems. The efficiency of the proposed solutions is confirmed by the results of yield calculations.<
