The Xilinx partial reconfiguration (PR)software tools has been an instrumental package for performing a wide variety of research on Xilinx FPGAs.  The toolkit provided a methodology for creating rectangular partial reconfiguration modules that could be swapped in and out of a static baseline design with one or more PR slots. This project presents an alternative PR toolkit called OpenPR that, for starters, provides similar functionality as the Xilinx PR Toolkit, yet is extendable to explore other modes of partial reconfiguration. The distinguishing feature of this toolkit is that it is being released as open source, and is intended to extend to the needs of individual researchers.
