The following table shows the F-Tile Ethernet Reconfiguration Avalon Memory-Mapped address ranges.
Table 49.  F-Tile Ethernet Reconfiguration Avalon® Memory-Mapped Address Ranges
Register Type Address Range
F-Tile AIB Config 0x0000 – 0x00FC
Soft CSRs 0x0100 – 0x0FFC
EHIP Registers 0x1000 – 0x5FFC
FEC/XCVRIF Registers 0x6000 – 0x9FFC

The Ethernet Reconfiguration interface provides access to the EHIP Avalon® memory-mapped address space for the local EHIP fracture, including MAC, PCS, FEC and XCVRIF, as well as soft CSRs implemented in the FPGA fabric. The layout of this register space is described in more detail in the F-tile Hard IP for Ethernet User Guide. All addresses in this section are byte addresses, although the registers described are always accessed on 32-bit boundaries.

The EHIP and FEC/XCVRIF Registers spaces are mapped differently for different ethernet modes (10g/25g, 50g, 40g/100g, 200g, 400g) and are described in theF-Tile Ethernet Intel FPGA Hard IP Register Map.

Table 50.  F-tile Ethernet Base Address Ranges
Ethernet Mode eth_reconfig Base Address
10g/25g 0x1000
50g 0x2000
40g/100g 0x3000
200g 0x4000
400g 0x5000

The following table shows the F-tile CSR address (Section 8 in F-Tile Ethernet Intel® FPGA Hard IP User Guide) mapping for channel 0/Quad 0 FGT 0. The CSR address mapping for different channels share the same byte offset. For example, channel 0 base address starts at 0x020_0000, and channel 8 base address is 0x120_0000. You can directly add the CSR byte offset address with base address of the channel to obtain the CSR address on particular channel. The CSR address is in byte offset, so the offset is directly added to base address without multiplication. To access this register, you must write bits 2-25 of this calculated address to the HSSI Control/Address CSR with the set_csr SAL command.

The following example shows CSR access decoding.

Assuming you would like to access Tx MAC Link Fault Config register (For details, refer to F-tile Hard IP for Ethernet Register Map) for Agilex F-tile channel 8.

Tx MAC Link Fault Config register byte offset = 0x1200

F-tile transceiver channel 8 base address = 0x1200000

AXI-Lite CSR read request address = 0x405*4 + 0x1200000 = 0x1201014 (byte addressing)

This request will be decoded and routed to Ethernet Reconfiguration interface for processing.
