# Dependencies and Requirements

## Dependencies

The USRP FPGA build system requires a UNIX-like environment with the following dependencies

- Xilinx ISE 12.2
- GNU Make
- (Recommended) GNU Bash

The N200 will work with the WebPack version of ISE.

## Requirements

- Xilinx ISE Platform Requirements

## What FPGA does my USRP have?

- USRP N200: Spartan® 3A-DSP 1800
- USRP N210: Spartan® 3A-DSP 3400

# Build Instructions

- Download and install Xilinx ISE 12.2
- To add xtclsh to the PATH and to setup up the Xilinx build environment run
  - `source <install_dir>/Xilinx/12.2/ISE_DS/settings64.sh` (64-bit platform)
  - `source <install_dir>/Xilinx/12.2/ISE_DS/settings32.sh` (32-bit platform)
- Navigate to `usrp2/top/{project}` where project is:
  - N2x0: For USRP N200 and USRP N210
- To build a binary configuration bitstream run `make <target>` where the target is specific to each product. To get a list of supported targets run `make help`.
- The build output will be specific to the product and will be located in the `usrp2/top/{project}/build` directory. Run `make help` for more information.

## N2x0 Targets and Outputs

### Supported Targets

- N200R3: Builds the USRP N200 Rev 3 design.
- N200R4: Builds the USRP N200 Rev 4 design.
- N210R3: Builds the USRP N210 Rev 3 design.
- N210R4: Builds the USRP N210 Rev 4 design.

### Outputs

- `build-<target>/u2plus.bit` : Configuration bitstream with header
- `build-<target>/u2plus.bin` : Configuration bitstream without header
- `build-<target>/u2plus.syr` : Xilinx system report
- `build-<target>/u2plus.twr` : Xilinx timing report
