Ettus Research USRP FPGA HDL Source
===================================
Welcome to the USRP FPGA HDL source code tree! This repository contains
free & open-source FPGA HDL for the Universal Software Radio Peripheral
(USRP™) SDR platform, created and sold by Ettus Research. A large
percentage of the source code is written in Verilog.
## Product Generations
This repository contains the FPGA source for the following generations of
USRP devices.
### Generation 1

### Generation 2
- Directory: __usrp2__
- Devices: USRP N2X0, USRP B100, USRP E1X0, USRP2
- Tools: ISE from Xilinx, GNU make
- [Build Instructions](http://files.ettus.com/manual/md_usrp2_build_instructions.html)
- [Customization Instructions](http://files.ettus.com/manual/md_usrp2_customize_signal_chain.html)
### Generation 3
- Directory: __usrp3__
- Devices: USRP B2X0, USRP X Series, USRP E3X0, USRP N3xx
- Tools: Vivado from Xilinx, ISE from Xilinx, GNU make

- [Simulation](http://files.ettus.com/manual/md_usrp3_simulation.html)
## Pre-built FPGA Images
Pre-built FPGA and Firmware images are not hosted here. Please visit the
[FPGA and Firmware manual page](http://files.ettus.com/manual/page_images.html)
for instructions on downloading and using pre-built images. In most cases, running the following
command will do the right thing.
$ uhd_images_downloader
## Building This Manual
This FPGA manual is available on the web at http://files.ettus.com/manual/md_fpga.html for the most
recent stable version of UHD. If you wish to read documentation for a custom/unstable branch you will
need to build it and open it locally using a web browser. To do so please install
[Doxygen](http://www.stack.nl/~dimitri/doxygen/download.html#srcbin) on your system and run the following commands:
$ cd docs
$ make
$ sensible-browser html/index.html
