Abstract
Some embodiments of the invention provide a configurable integrated circuit ('IC'). The IC includes a first set of circuits and a second set of circuits interspersed among the first set of circuits. Each set of circuits includes at least ten volatile configurable circuits. Several circuits in at least one of the sets are user multiplexers. Each particular user multiplexer has input and output terminals and has a set of select terminals for receiving a set of user-design signals that directs the particular multiplexer to connect a set of the input terminals to a set of the output terminals. The user-design signals are signals generated internally by the IC.
