Component Description
LL 10GbE MAC
The Low Latency Ethernet 10G MAC Intel® FPGA IP with the following configuration:
  • Speed: 10M/100M/1G/10G
  • Datapath options: TX & RX
  • Enable ECC on memory blocks: Not selected
  • Enable supplementary address: Selected
  • Enable statistics collection: Selected
  • Statistics counters: Memory-based
  • All Legacy Ethernet 10G MAC Interfaces options: Selected
For the design example with the IEEE 1588v2 feature, the following additional parameters are configured:
  • Enable time stamping: Selected
  • Enable PTP one-step clock support: Selected
  • Timestamp fingerprint width: 4
  • Time Of Day format: Enable both 96b and 64b Time of Day Format
PHY The 1G/10G and 10GBASE-KR PHY Intel® Arria® 10 FPGA IP. The design example uses the 1G/10G IP variant.
Address decoder Decodes the addresses of the components in each Ethernet channel.
Multi-channel address decoder Decodes the addresses of the components used by all channels, such as the Master TOD module.
Reset controller Synchronizes the reset of all design components.
Transceiver Reset Controller The Transceiver PHY Reset Controller Intel® FPGA IP. Resets the transceiver.
PLL Generates clocks for all design components.
ATX PLL Generates a TX serial clock for the Intel® Arria® 10 10G transceiver.
fPLL Generates a TX serial clock for the Intel® Arria® 10 1G transceiver.
MDIO Provides an MDIO interface to the external PHY.
FIFO The Avalon® streaming single-clock FIFO. Buffers the RX and TX data between the MAC IP and the client. The default depth is 512. To increase the depth of the FIFO, change the DC_FIFO_DEPTH and SC_FIFO_DEPTH parameter values from 512 to 2048, under altera_eth_fifo instance in <Example Design>/rtl/altera_eth_channel.sv.
Design Components for the IEEE 1588v2 Feature
Master TOD The master TOD for all channels.
TOD Sync Synchronizes the Master TOD to all Local TODs.
Local TOD The TOD for each channel.
Master Pulse Per Second Returns pulse per second (pps) for all channels.
Pulse Per Second Returns pulse per second (pps) for each channel.
PTP packet classifier Decodes the packet type of incoming PTP packets and returns the decoded information to the LL 10GbE MAC Intel® FPGA IP.
