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
