FPGA Application/Reference Design Example
Spartan-3A Starter Kit board demonstration design. Loaded at power-up.
Device DNA Reader: Reads the FPGA’s unique Device ID value and displays it on the character LCD
screen.
Fractal Generator: Computes fractal images in real time and displays on the VGA port. A user-
contributed design by Matthias Alles. Rotate knob to zoom fractal image; press surrounding push-
buttons to scroll the image.
ASCII Terminal: Implements a text terminal using an attached VGA display and PS/2 keyboard and
will communicate with HyperTerminal on a PC via an RS-232 serial connection.
STMicro M29DW323DT Parallel Flash Programmer: Communicates to a PC using HyperTerminal via
an RS-232 serial connection. Programs, erases, and reads the STMicro M29DW323DT parallel Flash
PROM on the Starter Kit board.
Scroll or Rotate Graphic
In this mode, rotate the knob to rotate the graphic image clockwise or counterclockwise.
Use the four push-button switches to scroll the graphic image up, down, left, or right.
Press the rotary knob to change to the “Scroll or Scale Graphic” mode.
Scroll or Scale Graphic
In this mode, rotate the knob to scale the size of the graphic image, zooming in and out.
Use the four push-button switches to scroll the resulting graphic image up, down, left, or
right.
Press the rotary knob to change to the “Restart AutoPilot, Speaker Volume Control” mode.
Restart AutoPilot, Speaker Volume Control
In this mode, rotate the knob to control the speaker output volume.
Press any of the four push-button switches to restart the AutoPilot function.
Press the rotary knob to change to the “Select MultiBoot Configuration Image” mode.
LCD Screen Control Option
While the demonstration design operates best with an attached VGA display, the on-board
LCD screen tracks similar functionality, as shown in Figure 1-5 . If no VGA display is
attached, then the “Scroll or Rotate Graphic” , “Scroll or Scale Graphic” , and
