FMC Carrier-S6™ Board Reference Manual Revision: March 26, 2013 Note: This document applies to REV B of the board. 1300 Henley Court | Pullman, WA 99163 (509) 334 6306 Voice and Fax Overview The FMC Carrier-S6 circuit board is a digital circuit development platform based on a Xilinx Spartan-6 LX45 FPGA. The large FPGA along with the high-pin count FMC socket, 128MByte DDR2 on-board memory, and compact PCB size make this an ideal FMC Host controller board for embedded processor designs based on Xilinx’s MicroBlaze. FMC Carrier-S6 is compatible with all Xilinx CAD tools, including ChipScope, EDK, and the free ISE WebPack™, so designs can be completed at no extra cost. The Spartan-6 LX45 is optimized for highperformance logic and offers:      6,822 slices, each containing four 6input LUTs and eight flip-flops 2.1Mbits of fast block RAM four clock tiles (eight DCMs & four PLLs) 58 DSP slices 500MHz+ clock speeds The FMC Carrier-S6 board includes Digilent's Adept USB2 system, which offers device programming and user-data transfer facilities.

The FPGA can be configured in two ways: a USBconnected PC can configure the board using the JTAG port any time power is on and a configuration file stored in the SPI Flash ROM can be automatically transferred to the FPGA at power-on. Adept USB Port JTAG Port USB Controller J2 M0 M1 UART Port 2 Serial Port 16Mbytes 3V3 Spartan-6 FT232HQ Numonyx SPI Flash (x4) SPI Port JP2 Load to enable boot from ROM Done J3 An on-board mode jumper (JP2) selects between JTAG/USB and ROM programming modes. If JP2 is loaded, the FPGA will automatically configure itself from the ROM. If JP2 is not loaded, the FPGA will remain idle after power-on until configured from the JTAG port. Both Digilent and Xilinx freely distribute software that can be used to program the FPGA and the SPI ROM. Programming files are stored within the FPGA in SRAM-based memory cells. This data defines the FPGA’s logic functions and circuit connections, and it remains valid until it is erased by removing power or asserting the PROG_B input, or until it is overwritten by a new configuration file. FPGA configuration files transferred via the JTAG port use the .bit or .svf file types. Xilinx’s ISE WebPack and EDK software can create .bit, .svf, .bin, or .mcs files from VHDL, Verilog, or schematicbased source files (EDK is used for MicroBlaze™ embedded processor-based designs). www.digilentinc.com page 2 of 7 Copyright Digilent, Inc.

The plug-in automatically translates iMPACT-generated JTAG commands into formats compatible with the Digilent USB port, providing a seamless programming experience without leaving the Xilinx tool environment. Once the plug-in is installed, the "third party" programming option can be selected from the iMPACT tools menu, and iMPACT will work as if a Xilinx programming cable were being used. All Xilinx tools (iMPACT, ChipScope, EDK, etc.) can work with the plug-in, and they can be used in conjunction with Adept tools. Adept’s high-speed USB2 system can be used to program the FPGA and ROM and exchange register-based and file-based data with the FPGA. The Adept application, an SDK, and reference materials are freely downloadable from the Digilent website. Power Supplies The FMC Carrier - S6 board requires an external 12V, 5A or greater power source with a coax centerpositive 2.1mm internal-diameter plug (a suitable supply is provided as a part of the FMC Carrier - S6 kit). Voltage regulator circuits from Analog Devices create the required 3.3V, 1.8V, 1.23V and VADJ supplies from the main 12V supply. The table below provides additional information, typical currents depend strongly on FGPA configuration, and the values provided are typical of medium-size/speed designs). FMC Carrier - S6 Power Supplies Supply 12V 3.3V 1.8V 1.23V VADJ Circuits FMC VCC12V0 FPGA I/O, USB ports, clocks, ROM FPGA aux, GPIO FPGA core 1V2, 1V8, 2V5, 3V3 Device IC15: ADP1850 IC15: ADP1850 IC15: ADP1850 IC23: LTC3546 IC23: LTC3413 Amps (max) 5A 4A 1A 3A 4.2A A power-good LED (LD3), driven by the wired-OR of all the power-good outputs on the supplies, indicates that all supplies are operating within 10% of nominal. The VADJ rail has to be enabled by logic implemented in the FPGA. To do this, set the SET_VADJ0 and SET_VADJ1 pins to indicate the desired voltage and drive VADJ_EN high. It is important to note that FPGA banks 0 and 1 are unpowered whenever VADJ_EN is low.

The DDR2 device, a Micron MT47H64M16-25E or equivalent, provides a 16-bit bus and 64M locations. The FMC Carrier - S6 board has been tested for DDR2 operation at up to an 800MHz data rate. The DDR2 interface follows the pinout and routing guidelines specified in the Xilinx Memory Interface Generator (MIG) User Guide. The interface supports SSTL18 signaling, and all address, data, clocks, and control signals are delay-matched and impedance-controlled. Address and control signals are not terminated. Two well-matched DDR2 clock signal pairs are provided so the DDR can be driven with low-skew clocks from the FPGA.

The SPI Flash can be programmed with a .bit, .bin., or .mcs file using the Adept software. An FPGA configuration file requires less than 12Mbits, leaving 116Mbits available for user data. Data can be transferred from a PC to/from the Flash by user applications, or by facilities built into the Adept software. User designs programmed into the FPGA can also transfer data to and from the ROM. V3 T13 R13 T14 V14 R15 Spartan-6 CS# SDI/DQ0 SDO/DQ1 WP#/DQ2 HLD#/DQ3 SCK SPI Flash A simple demo image has been loaded into the Serial Flash during manufacturing. It connects the User LEDs (LD0, LD1) to the User Switches (SW0, SW1). The image along with the project source is available on the Digilent website. Oscillators/Clocks The FMC Carrier - S6 board includes a single 100MHz Oscillator connected to pin T9 (T9 is a GCLK input in bank 2). The input clock can drive any or all of the four clock management tiles in the Spartan6. Each tile includes two Digital Clock Managers (DCMs) and one Phase-Locked Loop (PLL). DCMs provide the four phases of the input frequency (0º, 90º, 180º, and 270º), a divided clock that can be the input clock divided by any integer from 2 to 16 or 1.5, 2.5, 3.5... 7.5, and two antiphase clock outputs that can be multiplied by any integer from 2 to 32 and simultaneously divided by any integer from 1 to 32. PLLs use Voltage Controlled Oscillators (VCOs) that can be programmed to generate frequencies in the 400MHz to 1080MHz range by setting three sets of programmable dividers during FPGA configuration. VCO outputs have eight equally-spaced outputs (0º, 45º, 90º, 135º, 180º, 225º, 270º, and 315º) that can be divided by any integer between 1 and 128. USB-UART Bridge (Serial Port) The FMC Carrier - S6 includes an FTDI USB-UART bridge to allow PC applications to communicate with the board using a COM port. Free drivers allow COM-based (i.e., serial port) traffic on the PC to be seamlessly transferred to the FMC Carrier – S6 board using the USB port at J3 marked UART. The FTDI T10 2 TXD J3 part delivers the data to the SpartanRXD U10 “UART” 6 using a two-wire serial port with software flow control (XON/XOFF). Micro-USB FT232HQ Spartan-6 Free Windows and Linux drivers can be downloaded from www.ftdichip.com. After the drivers are installed, I/O commands from the PC directed to the COM port will produce serial data traffic on the T10 and Q10 FPGA pins. www.digilentinc.com page 5 of 7 Copyright Digilent, Inc.

The buttons and slide switches are connected to the FPGA via series resistors to prevent damage from inadvertent short circuits. The high efficiency LED anodes are connected to the FPGA via 390-ohm resistors, and they will brightly illuminate with about 1mA of current when a logic high voltage is applied to their respective I/O pin.

The FMC exposes 126 single-ended I/O, 102 of which can be configured as 51 differential pairs. The FMC interface spans over 4 PL I/O banks (banks 0, 1, 2, and Misc.). The FMC pin-out can be found in the FMC Carrier – S6 General UCF file. Quality Assurance All FMC Carrier - S6 boards are 100% tested during the manufacturing process. If any device on the FMC Carrier - S6 board fails test or is not responding properly, it is likely that damage occurred during transport or during use. Typical damage includes stressed solder joints and contaminants in switches and buttons resulting in intermittent failures. Stressed solder joints can be repaired by reheating and reflowing solder and contaminants can be cleaned with off-the-shelf electronics cleaning products. If a board fails test within the warranty period, it will be replaced at no cost. If a board fails test outside of the warranty period and cannot be easily repaired, Digilent can repair the board or offer a discounted replacement.
