Some embodiments of the invention provide a configurable integrated circuit (IC). The IC includes an interconnect circuit having a first set of input terminals and a set of output terminals. The interconnect circuit has several connection schemes for connecting the first input set to the output set. The IC also has a second set of input terminals for carrying a set of input signals, where at least several of the second set of input terminals overlap at least a plurality of the first set of input terminals. The IC further has a set of vias, where each via connects an input terminal in the first set with an input terminal in the second set. The interconnect circuit receives a control signal and based on this control signal connects the first input terminal set to the output set by using a particular one of the connection schemes.
