Due to a compatibility problem in different versions of Intel® Quartus® Prime software, you may see the following synthesis error if you compile the MAX® V project from Intel® Stratix® 10 GX Signal Integrity Development Kit.
Error (12006): Node instance "altera_pfl2_data_format_adapter" instantiates undefined entity "pfl_ii_parallel_flash_loader_2_0_altera_pfl2_data_format_adapter_altera_pfl2_data_format_adapter". Ensure that required library paths are specified correctly, define the specified entity, or change the instantiation. If this entity represents Intel FPGA or third-party IP, generate the synthesis files for the IP.
To work around this problem, you can open Altera Parallel Flash Loader II IP and regenerate HDL files manually.
This problem is scheduled to be fixed in future development kit installer release.
