thanks for your reply, the different build generate exactly the same binaries which just
not the same with the binary in uhd git repo.

Why no one have the answer or have the same question?
99.9% of the people on this list have no experience building the firmware or making
  modifications to it, they just use the as-supplied firmware.

The way the fpga code is setup, it's intended to be built with "make" rather than the vendors
  IDE, so it doesn't surprise me that you get topology-related errors.  But that's as much as  I know.
  I've never built it myself.

Also, the way FPGA "routers" work, there's a certain amount of Monte-Carlo decision making
  done in the way paths are laid out.  So two different "runs" with exactly the same codebase
  can yield different (but functionally identical) FPGA binaries.   The same thing happens with
  PCB routers--press the "route" button, it will be very often route the same circuit/physical placement
  with different lines.

Hi all,
I have some problems when compile the fpga source.
I open uhd-git\fpga\usrp1\toplevel\usrp_std\usrp_std.qpf with quartus II
then compile meet a lot of errors which is the path error like that:
Error (10054): Verilog HDL File I/O error at rx_buffer.v(25): can't open Verilog Design File "../../firmware/include/fpga_regs_common.v"
when I fix the path problem then compile success. but the generated rbf file is different from the one in rbf directory.
I use the newest git version.
