TOKUDEN Spartan-6 FPGA Board

TOKUDEN Spartan-6 Board is a cardsize FPGA evaluation board.

This board is equipped with a DDR2 memory and an USB2.0 interface. You can configure FPGA through on-board USB-JTAG.

 

Summary

TokushuDenshiKairo's FPGA evaluation board TKDN-SP6-45 and TKDN-SP6-16 are FPGA evaluation board which is equipped with Spartan-6. Spartan-6 is the newest FPGA of XILINX.

 

This board is equipped with high technology parts, but the system development using this board is not difficult at all. We offer USB 2.0 , DDR2 library , a sample reference design of FPGA and a sample Windows application software. You can make a data acquisition and control system quickly using these library and sample design.

 

This board was designed according to the feelings that "I want such a board".

 

For example, 2.54mm pitch pin headders draw 64 general purpose I/O ports. You can make an extended system with an usual universal board. Without a special, strange connector and taking the trouble to build a print circuit boards !

 

And the USB bus power supply is possible, it is not necessary preparing an AC adapter

The interface to PC is not LAN but USB, the wiring is settled clearly.

Because the board is very compact and thin, it does not interfere with you even if you put it on a desktop.

Spartan-6 FPGA Evaluation board

 

Because the communication with the PC is not ethernet but USB , there is not necessity to use the embedded processor such as MicroBlaze or PicoBlaze. A communication circuit is made only by a logic of FPGA. It is very easy and simple.

You can enjoy a sense of raw FPGA.

This is clearly the FPGA evaluation board which is usable immediately. You can rialize most application because FPGA is from 1 to 2.4 million gates class.

The difference with other brands

This board is different from the FPGA evaluation board of other companies. This board is compact size and does not interfere.

And because the communication with the PC is NOT Ethernet but USB, it is not necessary to use MicroBlaze and uCLinux.

 

Therefore the design of FPGA becomes simple and is overwhelmingly short at logic synthesize and place-and-route time.

You do not have to wait at long time anymore to compile FPGA.

 

Furthermore, the JTAG cable is unnecessary because on-board High speed USB-JTAG and dedicated software are provided.

You can begin FPGA development immediately and make efforts in a main profession.

Without being bothered by ethernet and the Softcore CPU.

    About sample design

    The sample design communicate with an internal logic of FPGA via USB,

    The main function as follows.

     

    (1) USB operation test

    It can retrieve contents of test pattern , the DDR2 SDRAM, contents of BlockRAM and  a current value of GPIO.

    Retrieved data can be shown as a VGA size (640x480) image.

     

    (2) Testing DDR2 SDRAM

    It can read and write the data of the up to 64M byte via USB.

    You can send data from FILE and readback and show as a VGA Image.

     

    (3) Open short test of I/O pin headder

    Among 64 I/O pin headers, one is H level and others become L level. (It is so-called walking '1')

    With an oscilloscope, open short test is possible.

    They become high impedance when reading from USB.

     

    (4) LED display

    D7 indicates while DDR2 SDRAM read operation

    D8 indicates while DDR2 SDRAM write operation

    D1-D6 counts up while push switch SW1 is pushed.

     

    The sample design is controled with application software "sp6test.exe".

    A working image of sp6test.exe is shown in the following figure.

     

    Troubleshoot of current sample design version

    A clock to DDR2 memory is not output

    It is a trouble of happen only in ISE12.1.

    Please update to ISE12.2, or please use ISE11.5.

     

    Some timing constraints are not met

    There does not seem to be the serias problem. We just improve design in order to solve this problem.

     

    Some errors are occurred when IN/OUT testing of the DDR2 memory.

    Because reading timing of the DDR2 memory does not match the right position with our DDR2 core,
    errors appear depending on a temperature change and individual difference.

    We just improve design in order to solve this problem.

     

    It becomes hot during operation

     

    USB-JTAG programming tool for FPGA and SPI ROM

    Because this board is equipped with high level USB-JTAG function, programming of FPGA and SPI ROM is very easy.

     

    To use the on board USB-JTAG function, you use sp6jtag utility software.

     

    To program FPGA, connect usb connector of this board to your PC and launch SP6JTAGW utility.

     

    It takes about 3 seconds for FPGA of TKDN-SP6-16 ,  about 10 seconds for TKDN-SP6-45.

    It takes about 30 seconds for SPI ROM under TKDN-SP6-16 ,  about 100 seconds under TKDN-SP6-45.

    There is not needed converting from BitStream file to MCS file with using the XILINX iMPACT.

     

     

     

     

    Application "LED photo sensor array"

    A demonstration. When I shade on the LED matrix with a hand, LED shines in rainbow color.

    This is an example which the LED is used as an optical sensor.

     

    The LED emits light when an electric current flows. On the contrary, the voltage occurs when exposed by light.

    Therefore, the LED can act as an optical sensor.

     

    FPGA measures the output value of LED optical sensor , calculates and controls the emission of light of the LED.

    The strength of emission of LED is controlled smoothly by delta-sigma DAC in FPGA.

     

    Because the sensitivity of the brightness of human eyes has a nonlinearity, six built-in DSP48 blocks of Spartan-6 is used to implement the third function and revise this human eyes' nonlinearity.

    Linear and smooth control of the LED is realized in this way.
