ABSTRACT:
The present invention provides an integrated circuit, comprising an array of components and programmable interconnect network for the array of components, said programmable interconnect network comprising a plurality of switch boxes being connected in a tree-based hierarchical architecture and providing selection and connection for the components responsive to configuration bits, switch boxes located at the lowest level of hierarchy are connected to the components; switch boxes in at least one level of hierarchy have different number of children from those in other levels of hierarchy. The present invention provides a hierarchical architecture with a vast variety of cell numbers, which facilitates circuit implementation. The present invention also offers greater layout flexibility.
