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] Specifies 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] Specifies 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.
