<p>A semiconductor integrated circuit comprises a first circuit block constituting an input circuit, a second circuit block constituted of a predetermined function block, a third circuit block constituting an output circuit. The first, second and third circuit blocks are cascade-connected in a normal operation. A testing additional circuit for performing a function test for the second circuit block, is provided only at an input side of the second circuit block, and the second circuit block is connected directly to the third circuit block through only interconnections with neither a logic gate nor a multiplexor. <IMAGE></p> |
