2.7. H-Tile Hard IP for Ethernet Intel FPGA Design Example Registers

Table 5.   H-Tile Hard IP for Ethernet Intel FPGA Hardware Design Example Register MapLists the memory mapped register ranges for the hardware design example. You access these registers with the reg_read and reg_write functions in the System Console.
Word Offset Register Type
0x000000 KR4 registers
0x000300 RX PHY registers
0x000400 TX MAC registers
0x000500 RX MAC registers
0x000800 TX Statistics Counter registers
0x000900 RX Statistics Counter registers
0x001000 Packet Client registers
Table 6.  Packet Client Registers You can customize the H-Tile Hard IP for Ethernet Intel FPGA hardware design example by programming the packet client registers.

Access

0x1000 PKT_CL_SCRATCH [31:0] Scratch register available for testing. RW
0x1001 PKT_CL_CLNT [31:0] Four characters of IP block identification string "CLNT" RO
0x1008 Packet Size Configure [29:0] Specify the transmit packet size in bytes. These bits have dependencies to PKT_GEN_TX_CTRL register.
  • Bit [29:16]: Specify the upper limit of the packet size in bytes. This is only applicable to incremental mode.
  • Bit [13:0]:
    • For fixed mode, these bits specify the transmit packet size in bytes.
    • For incremental mode, these bits specify the incremental bytes for a packet.
0x25800040 RW
0x1009 Packet Number Control [31:0] Specify the number of packets to transmit from the packet generator. 0xA RW
0x1010 PKT_GEN_TX_CTRL [7:0]
  • Bit [0]: Reserved.
  • Bit [1]: Packet generator disable bit. Set this bit to the value of 1 to turn off the packet generator, and reset it to the value of 0 to turn on the packet generator.
  • Bit [2]: Reserved.
  • Bit [3]: Has the value of 1 if the IP core is in MAC loopback mode; has the value of 0 if the packet client uses the packet generator.
  • Bit [5:4]:
    • 00: Random mode
    • 01: Fixed mode
    • 10: Incremental mode
  • Bit [6]: Set this bit to 1 to use 0x1009 register to turn off packet generator based on a fixed number of packets to transmit. Otherwise, bit [1] of PKT_GEN_TX_CTRL register is used to turn off the packet generator.
  • Bit [7]:
    • 1: For transmission without gap in between packets.
    • 0: For transmission with random gap in between packets.
0x6 RW
0x1011 Destination address lower 32 bits [31:0] Destination address (lower 32 bits) 0x56780ADD RW
0x1012 Destination address upper 16 bits [15:0] Destination address (upper 16 bits) 0x1234 RW
0x1013 Source address lower 32 bits [31:0] Source address (lower 32 bits) 0x43210ADD RW
0x1014 Source address upper 16 bits [15:0] Source address (upper 16 bits) 0x8765 RW
0x1016 PKT_CL_LOOPBACK_RESET [0] MAC loopback reset. Set to the value of 1 to reset the design example MAC loopback. 1'b0 RW
