A semi-conductor integrated circuit

摘要

A semi-conductor integrated circuit, as made, comprises a plurality of cells, each cell having a plurality of resources which comprise storage/programming resources and functional resources. The functional resources comprise routing resources and/or logic function resources according to the cell type. The resources available to one cell are augmented by utilising resources from at least one other cell, without preventing the donor cell from functioning independently. An hierarchical routing structure is disposed in successive layers. A matrix array of cells divided into zones has a zone porting arrangement for each zone. The successive layers of routing resource comprise: zone interconnect comprising local direct connection paths connecting at least some of the cells with some other cells; and medium connection paths extending from the zone porting arrangement and selectably connectable with at least some of the cells in a zone; and global connection paths having selectable connections with the zone porting arrangement of each zone; and ```one or more further successive levels of routing resource.
