Semiconductor integrated circuit

A semiconductor integrated circuit comprising:

• n first output circuit blocks and m second output circuit blocks which are provided such that adjacent first and second output circuit blocks are spaced at a regular first pitch;
• and
• n input circuit blocks provided parallel to a direction along which the first and second output circuit blocks are provided, the input circuit blocks being provided such that adjacent input circuit blocks are spaced at a regular second pitch,
• wherein the first and second output circuit blocks are provided such that at least part of ones of the first and second output circuit blocks alternate with the other ones of the first and second output circuit blocks and each of the first output circuit blocks is connected to a corresponding one of input circuit blocks by a first conductor line such that a length of the first conductor line is shortest between the first output circuit blocks and the corresponding ones of input circuit blocks, and
• second conductor lines are connected to the second output circuit blocks such that each second conductor line passes through a gap between the input circuit blocks.
