Contents

The basic idea behind this board is to have a development FPGA board, with a choice of big FPGA's and a VME compatible 2U Rack connector. The stock can be verified and updated on-line.

Type FPGA Rack Schematic UCF Description
V1.0 FPGA Rack V1.0 FPGA-Rack v1.0 Schematic PDF FPGA-Rack v1.0 UCF Files There are different FPGA mounted: Spartan 6 XC6SLX45, Spartan 6 XC6SLX100, Spartan 6 XC6SLX150

The boards are compatible with the FPGA Rack Backplane for interconnecting different boards with the help of the HES-SO Backplane Bus and the HES-SO VME IP Core.

A VHDL test code with the default UCF Files can be found at the EDA SVN Repository:

Leds and Buttons

There are 4 Dil switches and 4 Leds mounted on the FPGARack board. They are not properly indicated 0 - 3 therefore see the image below.

FPGA Rack V1.0 Leds and Buttons

Features

  • 2 Port Ethernet (one PTP physical)
  • USB FTDI
  • 2 UART
  • Flash 128Mb - 512Mb
  • Ram 128Mb - 256Mb
  • Spartan 6 LX45 - LX100 - LX150
  • 4 Leds
  • 4 Dil Switches
  • 1 Button
  • 106.25MHz Main Clock
  • VME compatible connector 3x32Pin
  • 2 Debug connectors 2x50Pin
  • 2 Mezzanine Connector ARM-EBS and FPGA-EBS compatible
  • Powered by USB or VME Power

VME connector logic levels

The I/O bank which interfaces the VME connector (and the little black connectors) can be powered with 3.3V or with 2.5V. A zero-Ohm resistor has to be soldered at the proper place near the FPGA.

Programmation

This board can be programmed in 2 ways,

  • first the FPGA can be directly programmed
  • second the FPGA can be programmed via the onboard Flash memory
