RapidWright is an open source project from Xilinx Research Labs that provides a new bridge to Vivado through reading and writing design checkpoint (DCP) files. Its mission is to enable power users greater flexibility in customizing solutions to their unique implementation challenges.
RapidWright also provides a new design methodology leveraging pre-implemented modules (modules that have been synthesized, placed and routed out-of-context). These pre-implemented modules can be cached, replicated and relocated using the RapidWright framework. We see pre-implmented modules as a way to build systematic shells and overlays and a core piece of strategy in achieving near-spec performance.
If you run into issues, feel free to file an issue on the Github issue tracker, or, for more broad questions/requests, post on our support forum. Documentation and Javadoc reference is also available.
