Abstract
Approaches for placement and routing of a circuit design are disclosed. Two or more modules of a circuit design are assigned to respective regions of a programmable integrated circuit. Placement and routing constraints are created for non-global resources of two or more modules of the circuit design. The placement and routing constraints restrict placement and routing of non-global resources of each of the two or more modules to respective regions of a programmable IC. Each non-global resource is used by at most one of the two or more modules. The two or more modules are placed. In response to the one of the placed circuit elements not being placed within the assigned region, the routing constraint on the one of the circuit elements is removed. The circuit design is routed.
