Hi sp, It is possible to use incremental implementation using the checkpoints generated by the build flow, but I've never tried it with USRPs. This is an advanced Vivado feature so you would need to write your own TCL code to use that feature. See the Xilinx documentation for details. Keep in mind that this is only for implementation (not for synthesis) and it's only recommended for small and isolated design changes.
Also, make sure when you run the build process that it's not regenerating the IP. IP generation/synthesis should only happen once then those results should be reused for each future build. But if you do "make cleanall" it will delete all the IP build results. A good way to reduce compilation time is to remove the parts of the RFNoC Image Core that you don't need. For example, if you are only doing RX then you can remove the TX paths, including the DUCs. If you're not using all the radio ports, you can remove the radio blocks and paths that you aren't using. And if you're not using the replay block then you should definitely remove that since that takes a long time to build. Also, you should not be rebuilding frequently, ideally. Simulation is a much faster way to debug and test changes to your code. So it's usually worth spending some time building a good testbench to make sure everything works the way you expect before you rebuild the FPGA.
