NetFPGA 10G v5.0.7

NetFPGA 10G v5.0.6

NetFPGA 10G v5.0.5

  • Added the Reference Router GUI interface: The Java GUI allows the user to change entries in the Routing Table and ARP cache as well as the router's MAC and IP addresses. It also provides updates on counter values and graphs of throughput and much more.

  • Updated statistics for packets droped counter at the interface.

NetFPGA 10G v5.0.4

  • Project related information stored in the bitfile

    We have updated the nf10_identifier module to store information related to date and time the synthesis started, board id, release tag, project identification, project features and misc details. So that once the bitfile is loaded in the FPGA, the driver can parse these registers and give some useful information to the users.

NetFPGA 10G v5.0.3

  • Some user updates/bug-fixes for the simulation framework.

NetFPGA 10G v5.0.2

NetFPGA 10G v5.0.1

  • to remove residual files when doing a "make clean".
  • renaming the bitfiles in accordance with the name of the project.

wiki for register monitoring system: https://github.com/NetFPGA/NetFPGA-public/wiki/Register-Monitoring-System

  • Updated xparam2regdefines.py to remove the "_OFFSET" suffix in the register names. Also updated the software monitoring system files to keep them in sync with the changes.

  • Driver fixes and updates:

  • removed libnl source code (from nic_oped contrib project). As modern OS have their own libnl packages (for Fedora it's called libnl3). It can be installed by yum install libnl3.
  • removed the copy of driver files in reference_nic_1g.
  • updated nic_oped driver to support kernel 3.12.5.
  • removed unused attributes of nf10driver.c in reference_nic driver.

Few of the limitations that still persist are:

  • FPGA only boots from flash if the written image (bitstream) is created using start-up clock (CCLK) during the bitgen process. In EDK, this process is hidden but you can verify this in the /hw/implementation/bitgen.ut file. The '-g StartUpClk:' option should be set to CCLK for proper working.

NetFPGA 10G v4.6

This is the forth release in the series of releases for the NetFPGA-10G beta community. It includes following new features:

  • Reference 10G Learning CAM Switch
  • Simple 10G Switch

Few of the limitations that still persist are:

  • FPGA only boots from flash if the written image (bitstream) is created using start-up clock (CCLK) during the bitgen process. In EDK, this process is hidden but you can verify this in the /hw/implementation/bitgen.ut file. The '-g StartUpClk:' option should be set to CCLK for proper working.

NetFPGA 10G v4.5

This is yet another release in the series of releases for the NetFPGA-10G beta community. It provides following new features:

  • OpenFlow Switch v1.0
  • Register System (based on EDK workflow)
  • SRAM FIFO
  • Official support for Xilinx 13.4 suite

Few of the limitations that still persist are:

  • FPGA only boots from flash if the written image (bitstream) is created using start-up clock (CCLK) during the bitgen process. In EDK, this process is hidden but you can verify this in the /hw/implementation/bitgen.ut file. The '-g StartUpClk:' option should be set to CCLK for proper working.

NetFPGA 10G v4.4 (Inishmore)

This is the second one in the series of releases for the NetFPGA-10G beta community. It contains following new features:

  • Faster and smaller implementation of PCIe DMA Egine and Device Driver.
  • Mechanics for porting NetFPGA-1G reference pipeline to the 10G platform.
  • Improved R/W timing for Flash ICs. Now takes around 5 mins to program each flash.

Few of the limitations that still persist are:

  • The nf10_configure utility will enter an indefinite held state if the NF10 driver is not installed.
  • FPGA only boots from flash if the written image (bitstream) is created using start-up clock (CCLK) during the bitgen process. In EDK, this process is hidden but you can verify this in the /hw/implementation/bitgen.ut file. The '-g StartUpClk:' option should be set to CCLK for proper working.

Bug fixes

  • Input Arbiter - a dead lock condition occurs for AXI Stream between two modules [resolved]

NetFPGA 10G v4.3

This is the first release published after the NetFPGA-10G has transition into beta. Contains all the features of its predecessors and is now available to a wider community.

NetFPGA 10G v4.2 (Isle of Man)

Isle of Man is another early release to the NetFPGA-10G alpha community. It contains a new feature of flash configuration. The projects are fully functional and tested, but there are few additional limitations listed below:

  • Programming each Flash IC takes around 30 mins.
  • The nf10_configure utility will enter an indefinite held state if the NF10 driver is not installed.
  • FPGA only boots from flash if the written image (bitstream) is created using start-up clock (CCLK) during the bitgen process. In EDK, this process is hidden but you can verify this in the /hw/implementation/bitgen.ut file. The '-g StartUpClk:' option should be set to CCLK for proper working.

The golden images (bitstreams) will not be present in the later releases. They will be provided as a separate link to reduce the overall size of the release.

NetFPGA 10G v4.1 (Skellig)

Skellig is an early release to the NetFPGA-10G alpha community. The designs in this projects are fully functional and tested, however we would like to point out the following issues:

  • The reference NIC in 1G and 10G designs operate reliably however with a low throughput. Please check the following page for more details: NIC's Benchmark
  • When running the system level simulation (make sim) for the reference_nic, we currently encounter a potential bug with isim which corrupts the outputs in the log file: nf10_oped_0_log.axi. If needed, use Modelsim until this bug is resolved.
  • Flash configuration is not contained in this release.
