An integrated circuit includes N configurable cells each including one functional input, one output, one propagation input and one output. The circuit includes a functional mode in which the N configurable cells are coupled by their functional input and their output to logic blocks with which they cooperate to form at least one logic circuit. The disclosed circuit also includes a test mode in which the N configurable cells are coupled by their propagation input and their output to the logic blocks and in which the output of the Nth configurable cell is coupled to a functional input of the first logic block to form an oscillator.
