Abstract

A circuit design tool places a circuit design, and after placing detects a hold violation of a path between a first flip-flop on a first IC die and a second flip-flop on a second IC die. The circuit design tool selects a window size based on an amount of the hold violation and determines an alternative path having a delay that resolves the hold violation. The alternative path is restricted to resources within an area of the window size on the second IC die. The circuit design tool replicates a plurality of instances of the alternative path in a plurality of areas of the second IC die and then routes the circuit design using the plurality of instances of the alternative path.
