Introduction
About the Virtex-5 FPGA Source-Synchronous Interfaces Tool Kit
The Virtex®-5 FPGA ML550 Source-Synchronous Interfaces Tool Kit provides a complete
development platform for designing and verifying applications based on the Virtex-5 LXT
FPGA family. This kit allows designers to implement high-speed applications with
extreme flexibility using IP cores and customized modules. The Virtex-5 LXT FPGA, with
its column-based architecture, makes it possible to develop highly flexible networking
applications.
The Virtex-5 FPGA ML550 Source-Synchronous Interfaces Tool Kit includes the following:
•Virtex-5 FPGA ML550 Networking Interfaces Development Board (XC5VLX50T-
FFG1136 FPGA)
•5V/6.5 A DC power supply
•Country-specific power supply line cord
•USB B-to-A cable
•Xilinx®LVDS Loopback board PN 0431395
•Documentation and reference design CD-ROM
Optional items that also support development efforts include:
•Xilinx ISE®software
•JTAG cable or Xilinx Platform Cable USB
For assistance with any of these items, contact your local Xilinx distributor or visit the
Xilinx online store at www.xilinx.com.
The heart of the Virtex-5 FPGA ML550 Source-Synchronous Interfaces Tool Kit is the
ML550 Development Board. This manual provides comprehensive information on Rev 1
and later revisions of this board.

Installation
Silicon Labs USB-to-RS232 Bridge Chip Driver Installation
Assumptions:
♦PC operating system is Microsoft Windows XP
♦No previous versions of this driver have been installed on the PC
♦The ML550 board is powered OFF
♦The USB B-to-A cable is installed between the ML550 and the PC
1. Copy the ML550 BERT REV1.x.zip file from the kit CD-ROM to C:\.
2. Unzip the file. When this file is unzipped, a folder called ML550 BERT REV1.x is
created.
3. Locate the self-extracting ZIP file CP210x_Drivers.exe in the folder
C:\ML550 BERT Rev1.x\USB_2_Serial Driver. Double-click on this file.
If the default target directory isn't changed, the folder C:\SiLabs\MCU\CP210x is
created. This folder contains various drivers.
4. Turn on the ML550 power.
Windows XP recognizes that new hardware is present, and opens the Add New
Hardware Wizard.
5. Choose Install from a list or specific location and click Next.
6. Choose Search for the best driver in these locations. Enter the path
C:\SiLabs\MCU\CP210x\WIN and click Next.
7. The wizard installs a driver and reports:
The wizard has finished installing the software for CP2101 USB
Composite Device.
Click Finish.
8. Windows XP now recognizes the USB to Serial Bridge and wants to install its driver as
well. Repeat step 5 and step 6.
9. The wizard installs another driver and reports:
The wizard has finished installing the software for CP2101 USB to
UART Bridge Controller.
10. Windows XP displays:
Your new hardware is installed and ready to use.
Note: This driver assigns itself the lowest unassigned serial COM port number. This number varies
with PC hardware configuration. COM3 or COM4 is typically assigned.

BERT GUI Tcl Interface Installation
1. Locate executable file ActiveTcl8.4.7.0-win32-ix86-108887.exe in
C:\ML550 BERT REV1.x and double-click on it.
2. The Active State Active Tcl installer opens. Follow the dialog and accept the defaults.
At the end of the process, the installer reports the folders created during the install.
Click Finish.
3. Create a GUI shortcut for the Windows desktop:
a. Locate executable file gui_rev1.x.exe in
C:\ML550 BERT REV1.x\GUI_Rev1.x.
b. Right-click on this file and choose Create shortcut.
c. Drag the shortcut to the Windows XP desktop.
The BERT GUI is now ready to use.
ML550 Board Startup and Operation
1. Turn OFF the ML550 power.
2. Install either the LVDS Loopback board across the six LVDS Samtec connectors (if not
already installed), or install a single Blue Ribbon cable between the center TX and RX
Samtec connectors, P46 and P6 respectively.
3. Install the Compact Flash card into the J21 socket (if not already installed).
4. Confirm that the flash card image select rotary switch SW9 is set to position 0.
5. The CLOCK MOD 1 & 2 parallel programming DIP switches default to all OFF and can
be safely ignored.
The BERT test uses Clock Module 2 / U19. The GUI sets the Clock Module 2 / U19
initial frequency to 400 MHz.
6. Turn ON the ML550 power. The DONE LED D19 should come on.
7. On the PC, double-click on the gui_rev1.x.exe shortcut. The BERT GUI launches.
8. At the upper left are two selection boxes. The upper chooses the COM port, the lower
chooses the test type. Click on the upper and select COM4. Click on the lower and
select PRBS15.
9. Click on the big Start/Restart button.
If the COM port is correct, the test begins.
If the COM port is not correct, the GUI most likely will hang. If this occurs, close and
relaunch the application. When repeating the selection sequence, choose COM3. If this
also fails, repeat this procedure choosing a lower COM port number each time
through.
Some computers have more than four COM ports. It is possible that the USB-to-COM
bridge driver will select a COM port that the GUI will not communicate with (e.g.,
COM14.) The workaround in this instance is to go to:
Control Panel -> System -> Hardware -> Device Manager -> Ports
Identify the port selected by the CP210x USB to UART driver. If the COM port is not
COM1, COM2, COM3, or COM4, change the port using this path:
Control Panel -> System -> Hardware -> Device Manager -> Ports -> CP210x USB
to UART-> Port Settings -> Advanced COM Port Number

Select change to COM# where # is either 1, 2, 3, or 4.
10. The GUI reflects the frequency set at Clock Module 2 and initially reports 400 MHz.
More information resides in the file
C:\ML550 BERT REV1.x\DDR_8TO1_16CHAN_PICO_REV1.x\README.doc.
Also refer to the ML550 Networking Interfaces Board.ppt presentation on
the kit CD-ROM.
11. The clock frequency can be changed by clicking on the +100 MHz, +10 MHz,
–100 MHz, and –10 MHz GUI buttons to the left of the Frequency display. More
detailed information is available in the CD file BERTGUI_README.doc.

Clock Generation
The clock generation section of the ML550 Development Board provides all necessary
clocks for the Virtex-5 FPGA. Eight clock sources are provided:
•Epson EG2121CA 2.5V 250-MHz differential LVPECL oscillator (Y4) for general use
•Epson EG2121CA 2.5V 200-MHz differential LVPECL oscillator (Y3) for Virtex-5
FPGA ISERDES support
•Epson EG2121CA 2.5V 133-MHz differential LVDS oscillator (Y2) for DDR memory
interface
•Epson SG8002CA 3.3V 33-MHz LVCMOS single-ended oscillator (Y1) for SystemAce
device (U13)
•Two differential SMA clock inputs (CLOCK-1: J3, J1 and CLOCK-2: J4, J2)
•Two clock synthesizer ICS8442 devices (U18,U19)
The differential SMA clock inputs are connected to the global clock inputs of the FPGA. An
onboard 200-MHz oscillator calibrates the I/O delay, and an onboard 250-MHz oscillator is
provided for general use.
The two ICS8442 clock synthesizer devices output differential LVDS clocks in the
31.25 MHz to 700 MHz range.
The on-chip LVDS differential terminator is recommended for use in designs. The clock is
received by an IBUFGDS module, and beneath that module instantiation, the synthesis
attribute DIFF_TERM must be set to TRUE. Refer to the Virtex-5 FPGA User Guide (UG190)
for information and examples using SelectIO primitives for LVDS inputs.
Table 3-1 shows the clock generation components for the ML550 board.
