Circuit module generation for programmable integrated circuits

An exemplary method of implementing a circuit design for a programmable integrated circuit (IC) includes, on at least one programmed processor, performing operations including: generating a description of circuit components of the circuit design including first portion of a circuit module that is independent of assignment of resources of the programmable IC; assigning a plurality of the resources of the programmable IC to a plurality of the circuit components including determining at least one resource assignment for the circuit module; and generating a physical implementation of the circuit components for implementation in the programmable IC, including generating a second portion of the circuit module that is dependent on the at least one resource assignment, and combining the second portion of the circuit module with the first portion of the circuit module.
