  • Number of Channels of 10GE/25GE: Single Channel
  • Enable RSFEC: Selected
  • First RSFEC Lane: first_lane0(channel_0), first_lane1(channel_5), first_lane2(channel_10), or first_lane3(channel_15)
  • The FEC mode is set to fractured mode.

Two Channels 10GE/25GE with RS-FEC Variant

100GE with RS-FEC Variant

You can use the following channel placements for a four-channel Native PHY with single RS-FEC block without PTP variant.

In 100GE tab, Select Ethernet IP Layers: MAC+PCS+RSFEC.

Following are the IP tab parameter settings for these channel placements:

  • Select Core Variant: Single 100GE with optional RSFEC

  • Channel 16/17 when using EHIP_CORE2
  • Channel 18/19 when using EHIP_CORE3
Following are the parameter settings for these channel placements:
  • Select Core Variant: 100GE or 1 to 4 10GE/25GE with optional RSFEC and 1588 PTP
  • Number of Channels of 10GE/25GE: Single Channel
  • Active Channel(s) at startup: 10G/25GE Channel(s)
  • Enable IEEE 1588 PTP: Selected
  • Enable RSFEC: Selected
  • When IEEE1588/PTP channel placement restriction is set to EHIP0/2(EHIP_CORE_0/EHIP_CORE2), the First RSFEC Lane should set to first_lane3(channel_3 or channel_15).
  • When IEEE1588/PTP channel placement restriction is set to EHIP1/3(EHIP_CORE_1/EHIP_CORE3), the First RSFEC Lane should set to first_lane0(channel_8 or channel_20).
  • The FEC mode is set to fractured mode.
