2.5.1. Packet Generator Programming Sequence

You can initiate the packet transmission from the packet generator to the IP core by programming Packet Size Configure, Packet Number Control, and PKT_GEN_TX_CTRL registers.

The programming sequence varies based on a selected mode PKT_GEN_TX_CTRL[5:4]:

In Random Mode:

  1. Set Packet Number Control[31] to 0.
  2. Set PKT_GEN_TX_CTRL[1] to 0 to start the packet transmission through the packet generator.
  3. Set PKT_GEN_TX_CTRL[1] to 1 to stop the packet generator.

In Fixed/Incremental Mode—with fixed number of packets:

  1. Configure Packet Size Configure.
  2. Configure the number of packets: Bit [31] must be set to specify Packet Number Control[30:0]
  3. Set PKT_GEN_TX_CTRL[1] to 0 to start the packet transmission through the packet generator.
  4. The packet generator stops when the number of packets reaches 0.

In Fixed/Incremental Mode— without fixed number of packets:

  1. Configure Packet Size Configure.
  2. Set Packet Number Control[31] to 0.
  3. Set PKT_GEN_TX_CTRL[1] to 0 to start the packet transmission through the packet generator.
  4. Set PKT_GEN_TX_CTRL[1] to 1 to stop the packet generator.
