[TonyWu78]

Dear:

I am try to read those Verilog file. however the tools report some Error. It seems that some references missing in the design. How can I fix this issue? Are those references FPGA blocks?

Thanks very much.

That's because sirv_gnrl_dffl module is defined in the file: sirv_gnrl_dffs.v. Check your compiler to see how to resolve it.

the simplest way is split that file into multi files that contain one module in one file.
