Build flow for implementing artificial intelligence applications in programmable integrated circuits
A design for a programmable integrated circuit (IC) is synthesized and includes an inference engine and a data transformer. A portion of the design including the data transformer is designated as a dynamic function exchange (DFX) module. The inference engine is excluded from the DFX module. The design is implemented, by placing and routing, such that the DFX module is confined to a defined physical area of the programmable integrated circuit. An abstract shell for the design specifying boundary connections of the DFX module as placed and routed is generated. A locked version of the design as placed and routed with the DFX module removed is generated. The method includes implementing a different data transformer as a further DFX module for the design using the abstract shell.
