Building bricks of a network on chip

The present invention relates to a brick for the assembly of a circuit, in particular a mesh ring, by juxtaposition of similar bricks, comprising a longitudinal conductor section extra-connection (14) connecting two terminals (14-1 , 14-2) located on opposite transverse edges of the brick on a first axis; two longitudinal conductor segments intra-connection (18) connecting circuitry (20) of the brick to respective terminals (18-1, 18-2) located on the opposite transverse edges on a second axis symmetrical to the first axis with respect the center of the brick. The brick further comprises a transverse conductor segment of non-connection (12) connecting two terminals (12-1, 12-2) located on opposite longitudinal edges of the brick on a third axis; and two transverse conductor segments intra-connection (16) connecting circuitry (20) of the brick to respective terminals (16-1, 16-2) located on opposite longitudinal edges on a fourth symmetry axis to the third axis the center of the brick.
