The AXI slave VIP has two agents which are axi_slv_agent and axi_slv_mem_agent . If you want to generate your own traffic, use the axi_slv_agent and get_rd_reactive . The axi_slv_mem_agent has its own method of generating traffic.

The best technique is to place the read response which is shown in the example design simset sim_all_config . The procedure is shown here:

1. In the read driver of the slave agent, use the get_rd_reactive to receive the read command,

2. Fill in the transaction read data information and send it back to the AXI slave VIP interface. Because both the get_rd_reactive and send are blocking, they have to be included in the initial and forever blocks without any blocking events. See the following code example:

//slave VIP agent gets read transaction cmd information, fill in data information and send it back to Slave VIP interface

initial begin

forever begin

slv_agent.rd_driver.get_rd_reactive(rd_reactive);

fill_payload(rd_reactive);

fill_ruser(rd_reactive);

fill_beat_delay(rd_reactive);

slv_agent.rd_driver.send(rd_reactive);

end

end
