4.5.4.1. 100GE MAC+PCS with Optional RS-FEC Dynamic Reconfiguration Hardware Design Example Components

Figure 50. 100GE MAC+PCS with Optional RS-FEC Dynamic Reconfiguration Hardware Design Example High Level Block Diagram
The E-Tile Dynamic Reconfiguration Design Example includes the following components:
  • E-Tile Dynamic Reconfiguration Design Example core. The IP core consists of four 25G channels with optional RS-FEC or one 100G channel.
  • Client logic that coordinates the programming of the IP core and packet generation.
  • Avalon® memory-mapped interface address decoder to decode reconfiguration address space for E-Tile Hard IP for Ethernet core and RS-FEC modules during reconfiguration accesses.
  • JTAG controller that communicates with the System Console. You communicate with the client logic through the System Console.

The hardware design example uses run_test command to initiate packet transmission from packet generator to the IP core. By default, the internal serial loopback is disabled in this design example. Use the loop_on command to enable the internal serial loopback. When you use the run_test command to run the hardware test in the design examples, the script tests 100GE with RS-FEC. Use the run_test_dr to run the hardware test to perform all reconfigurable switches. The client logic reads and print out the MAC statistic registers when the packet transmissions are complete.

The following sample script illustrates a reconfiguration sequence:

source hwtest/main.tcl
set BASE_EHIP 0x400
#DR to 25GNF
# configure dr_cfg_ch_en register
reg_write $BASE_EHIP 0x13 0xf;
# configure dr_cfg_fec_en register
reg_wrtie $BASE_EHIP 0x15 0x0;
# configure dr_control and trigger reconfig registers
reg_write 0x4009 0x1;
The following sample output illustrates a successful hardware test run for 100GE, switching from 100G Ethernet with RS-FEC to 100G Ethernet variation: 
% cd hwtest/altera_dr
% run_test_dr_sw "100G_rsfec" "100G_nofec"
