Advances in FPGA density and complexity have not been matched by a corresponding improvement in the performance of the implementation tools. Knowledge of incremental changes in a design can lead to fast turnaround times for implementing even large designs. A high-level overview of an incremental productivity flow, focusing on the back-end FPGA design is provided in this thesis. This thesis presents a management paradigm that is used to capture the design specific information in a format that is reusable across the entire design process. A C++ based internal data structure stores all the information, whereas XML is used to provide an external view of the design data. This work provides a vendor independent, universal format for representing the logical and physical information associated with FPGA designs.
