Abstract

See full text

Methods and systems are disclosed for placement and routing of a circuit design. A set of timing constraints is retrieved that specifies timing for objects included in a first shell circuit design configured to provide an interface for communication between the circuit design and the set of dedicated hardware resources on an IC. One or more objects of the first shell circuit design that do not affect timing of the circuit design are identified and removed from the first shell circuit design to produce a second shell circuit design. The circuit design is placed and routed according to timing constraints specified for objects of the first shell circuit design that are included in the second shell circuit design. The placed and routed circuit design is stored in a memory circuit.
