ABSTRACT:
A programmable logic array device in which programmable logic regions are arranged in groups of four is provided. The device includes direct connect conductors for carrying signals totally within one group of four regions as well as to certain adjacent programmable logic regions, local conductors for carrying signals within groups and among adjacent groups, and global conductors for carrying device-wide signals. Connections among the various conductors, and between conductors and programmable logic regions, are provided to optimize the connection resources by avoiding switched conductor paths wherever possible.
