Efficient arrangement of interconnection resources on programmable logic devices

摘要

Interconnection block arrangements for selectively interconnecting logic on a programmable logic device is provided. Programmable logic connectors within the interconnection blocks may be programmed to route signals between the various conductors on the device and to route signals from various logic regions on the device to the various conductors. The interconnection blocks are arranged to optimize the use of metallization resources and to increase interconnectivity and logic density.
