2. Overview
Below is a high-level overview of the steps required to quickly get the Sonoma design
running by downloading and running the FPGA project. Detailed instructions for each
step are provided in the following pages.
The Sonoma (MAXREFDES14#) subsystem
reference design will be referred to as the Sonoma throughout this document.
1. Connect the Sonoma board to the J5 port of a LX9 MicroBoard as shown in
Figure 1.
Ensure the connector is aligned as shown in
Figure 2.
2. Connect the power supply and the load to the Sonoma board.
3. Download the latest
RD14V01_00.ZIP
file located at the Sonoma page.
4. Extract the
RD14V01_00.ZIP
file to a directory on your PC.
5. Open the Xilinx SDK.
6. Download the bitstream (.BIT) file to the board. This bitstream contains the FPGA
hardware design and software bootloader.
7. Open a terminal program to communicate with FPGA board.
8. Use Xilinx SDK to download and run the executable file (.ELF) on the
MicroBlaze™.

3. Included Files
The top level of the hardware design is a Xilinx ISE Project Navigator Project (.XISE) for
Xilinx ISE version 13.4. The Verilog-based HDL design instantiates the MicroBlaze core,
the support hardware required to run the MicroBlaze, and the peripherals that interface
to the Pmod ports. This is supplied as a Xilinx software development kit (SDK) project
which includes a demonstration software application to evaluate the Sonoma subsystem
reference design. The lower level c-code driver routines are portable to the user’s own
software project.
