Abstract: A platform design including a module black-box instance is loaded into computer hardware. Using the computer hardware, synchronous boundary crossings between a static region and the module black-box instance of the platform design are identified and objects of the platform design included in the synchronous boundary crossings are marked. Using the computer hardware, unmarked objects are removed from the platform design to generate a shell circuit design. A custom circuit design is implemented based on the shell circuit design and timing constraints corresponding to objects remaining in the shell circuit design.

Abstract: Partial reconfiguration of a programmable integrated circuit can include loading, using computer hardware, a platform design including a module black-box instance corresponding to a user design and marking, using the computer hardware, data of the platform design including data relating to synchronous boundary crossings between the platform design and the module black-box instance and implementation data for the platform design within an extended routing region available for routing the user design. Unmarked data can be removed from the platform design resulting in a shell circuit design. The user design can be implemented based on the shell circuit design and timing constraints corresponding to the marked data in the shell circuit design.
