XS40 Board Tutorial

This example will show you how to access the onboard 7-seg LED connected to the FPGA. The first step is to generate the bit stream for the FPGA:

  1. Run Xilinx Foundation Project Manager.
  2. Click OK to create a new project.
  3. Type "tut1" for name and browse/select "c:\temp" for directory and click the HDL flow button followed by OK
  4. Download (wrled.vhd*, xs40.vhd,  tut1.ucf) into "c:\temp\tut1".
  5. Add the two VHDL files to your project using menus item "Synthesis - Add HDL Source Files(s)...".
  6. Click the big "Synthesis" button and select "XS40" for Top Level, "XC4000XL" for Family and "4010XLPC84" for Device, then click Run.
  7. Click the big "Implementation" button, then click Run. When complete, exit Project Manager.
    You are done!
Now you have to download the bitstream file onto the XS40 board:
  1. Open a "Command Prompt" terminal and cd to "c:\temp\tut1".
  2. Make sure your XS40 board is powered up and connected to the computer.
  3. Type "xsload tut1.bit" on the prompt and hit "enter".
    You are done!

* NOTE: you are not provided with the complete wrled.vhd code, you need to finish the code before the XS40 board will count properly
