Re: [USRP-users] additional Verilog file in OOT RFNoC block

Hello Dixon, Daniel's suggestion works, but that would mean adding a hard-coded path into the fpga build system. It does the trick, but it is not recommended. The OOT module has its own Makefile.srcs that intends to contain all the HDL code that is required for the module. The procedure is the
