Hi, Nick,

Thanks a lot!
Do you know which file is same asĀ usrp_std.v that is responsible for binding all modules together?

The USRP1 used an Altera FPGA. The USRP E100 uses a Xilinx Spartan-3A FPGA. The FPGA code you want to be modifying is in the fpga/usrp2/top/E1x0 directory.

Hi, all,

We have made a FPGA FFT module.
We downloaded the UHD source code from
We modified the usrp_std.v under
to link our FFT module between rx_buffer and USB.
We have successfully compiled the usrp_std.qpf in Quartus II 9.1.
How can we make it effective in our USRP E100?

We found the way to update FPGA firmware in usrpe1xx-FAQ
But what we want to update is the FPGA code.

Thanks a lot!
