[The problems] In a semiconductor integrated circuit in which tilted wiring is used, the tilted wiring cannot be used effectively since the arrangement of blocks is restricted. [Means for solving] In the semiconductor integrated circuit consisting of at least a first block, a second block and a third block, the third block B5 is diagonally arranged between the first bock B1 and the second block B2 at a predetermined angle of approximately 45 degrees to the both blocks, the first block B1 includes at least a first output P1, the second block B2 includes at least a first input pin P2, the third block B5 includes at least a second input pin Q1 and a second output pin Q2, the first output pin P1 and the second input pin Q1 are connected by a first wiring L1, and the second output pin Q2 and the first input pin P2 are connected by a second wiring L2. Herewith, the degree of integration can be increased and the tilted wiring can be effectively used.
