Programmable interconnection group arrangements for selectively interconnecting logic on a programmable logic device are provided. Interconnection groups 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 groups provide routing flexibility and efficiency without using excessive amounts of interconnection resources.
