Abstract:
Interconnect circuitry for use in a programmable logic device that has a plurality of logic regions, comprising:a plurality of interconnection conductors of two types that are configured to convey signals to, from, and/or between regions; anda connector that is configured to selectively connect a plurality of connector input signals to one interconnection conductor of one type where one of the connecter input signals is from another interconnection conductor of a different type, the connector being further configured to respond to a selection control signal on the programmable logic device which can vary in logical state from time to time during operation of the programmable logic device, the connector selecting different ones of the connector input signals at different times depending on the logical state of the selection control signal at each such time,whereby signals are selectively transitioned between the two interconnection conductors of different types when the connector input signal that is from the interconnection conductor is selected.
