ABSTRACT:
A method and apparatus for connecting a load track (3) of a programmable interconnect to a plurality of intersecting driver tracks (2) of the programmable interconnect. The apparatus comprises a chain of connection cells (9;15), each connection cell being operable to connect the load track of the programmable interconnect to an associated intersecting driver track. Each cell also comprises connection signal receiving means arranged to receive a connection signal and activation signal receiving means arranged to receive an activation signal. The apparatus also comprises connection means arranged to connect the load track of the programmable interconnect to the associated intersecting driver track of the programmable interconnect when the connection signal receiving means has received a connection signal and the activation signal receiving means has received an activation signal. The apparatus also comprises activation signal propagating means arranged to propagate the activation signal to the next cell in the chain when the connection signal receiving means has not received a connection signal and the activation signal receiving means has received an activation signal.
