Integrated circuit power supply network

Abstract

An integrated circuit including an assembly of functional blocks and an interconnection network formed of at least N levels of conductive tracks separated by conductive via levels, the interconnection network including a power supply network comprising a first assembly of substantially parallel rails placed at the N-th track level, and a second assembly of substantially parallel rails placed at the (N−1)-th track level under the first rail assembly, the rails of the first assembly being non-parallel to those of the second assembly, the power supply network further including, for each functional block, a third assembly of power supply rails placed at the (N−2)-th track level above the elements of the considered block, and in which the rails of the second assembly form an acute angle smaller than 80° with the rails of each third rail assembly.
