A short description of the FPGA-EBS board is found on the ISI Project Page.

Board families

There are several versions of FPGA EBS Boards. The stock can be verified and updated on-line.

Type FPGA-EBS Full board FPGA-EBS Student board FPGA-EBS Mezzanine Schematic UCF Description
V2.1 FPGA EBS V2.1 boards 30-35 FPGA EBS Student Version V2.1 boards 11-13 FPGA EBS Mezza V2.1 boards 40-41 FPGA-EBS v2.1 Schematic PDF XC3S1200e
XC3S500e
Improved second version of FPGA-EBS comes with a Xilinx XC3S500e or a XC3S1200E. Note that there is a different UCF Pin constraining file depending on the FPGA type. Furthermore there is a xcf04s Xilinx Platform Flash for persistent configuration.
V2.0 FPGA EBS V2.0 boards 21-28 FPGA EBS Student Version V2.0 boards 1-8 Not existing FPGA-EBS v2.0 Schematic PDF XC3S500e Second FPGA-EBS Version comes only with Xilinx XC3S500E
V1.0 FPGA EBS V1.0 FPGA EBS Student Version V1.0 FPGA EBS Mezza Version V1.0 FPGA-EBS v1.0 Schematic PDF Not available First FPGA-EBS Version comes with a Xilinx XC2S150 or XC2S250 FPGA.
Please note that for Spartan 2 is no longer supported by Xilinx, an ISE Version <= 9.2i has to be used

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

UCF Pin Differences

On the FPGA-EBS v2.X Boards, you can find two different FPGA Spartan3 Chips.

There are 3 Pin differences between Boards with XC3S500E and XC3S1200E.

Pin Function Pin on XC3S500E Pin on XC3S1200E
ParallelPort2(16) F4 E6
MezzanineData(9) E17 E3
sdCke P15 E4

Other changes between FPGA-EBS V2.0 and V2.1

There are some other changes made in the Ethernet part of those boards. Several bugs were changes and corrected.

  • TCT and RCT Pins of the Ethernetconnector were strapped to 3.3V, and decoupled with Capacitors (C59 & C104)
  • Serial Capacitors on the RX+ and RX- lines were replaced by 0Ohm Resistors (R61 & R63)
  • Proper Reset circuit for the Ethernetphy is put on place (D13, D14, R62 & C108)
