Abstract:
Aspects of the present disclosure relate to adaptive mesh wiring. A clock signal is provided to a clock mesh area, wherein the clock mesh area includes a plurality of wires configured in a grid. A pair of loads with impermissible skew within the clock mesh area is identified based on a threshold value. A mesh network area partition enclosing the pair of loads with impermissible skew is determined. Modifications are then made to the mesh network area partition to attempt to reduce skew. In some embodiments, a wire width of a portion of wires included in the mesh network area partition is increased. In some embodiments, a wire is added in between two wires present in the mesh network area partition.
