User Packet Data
If the DATA_INC_PATTERN parameter is set to 0, you can set the payload
of each packet to contain any byte value. To set the payload, invoke the
user_packet task before calling the send_pkt task. Once all the
payload bytes of the packet have been set, the send_pkt task, with the
user_data_control field set, uses the data contained in the internal
array for the payload. Do not call the user_packet task again until the
send_pkt task has completed the packet transfer, or else data corruption
may occur.
To invoke the user_packet task, use the following syntax within the
testbench:

The send_pkt and rcv_pkt tasks are normally invoked using
a Verilog fork and join statement. Each task must finish
before invoking another similar task call; that is, you cannot fork
two send_pkt tasks on the same Atlantic generator
instantiation.
