A system, method and computer program product are provided for determining routing of data paths in interconnect circuitry for an integrated circuit. The interconnect circuitry on a first side provides a narrow interface for connection to a first device, and on a second side provides a wide interface for connection to a distributed plurality of further devices. Each data path is associated with one of the further devices and provides a connection through the interconnect circuitry between that associated further device and the first device. The method comprises the steps of defining a plurality of cells to be provided along the wide interface, each of the further devices being associated with at least one of the cells, and defining the interconnect circuitry as an array of blocks formed in rows and columns, with each cell abutting one of the columns. Further, the method includes the steps of providing a predetermined set of tiles, each tile providing a predetermined wiring layout, and for each block, applying predetermined rules to determine one of the tiles to be used to implement that block. The predetermined rules take into account the location of the block in the array and the association between the plurality of further devices and the plurality of cells, ensuring that each data path provided by the interconnect circuitry has the same propagation delay. By such an approach, a structured routing method is provided that uses predetermined tiles enabling a layout design for the interconnect circuitry to be readily produced whilst ensuring that the propagation delays are matched for each of the data paths within the interconnect circuitry.
