5.1.5. Source Auxiliary Packet Generators

The source core uses various auxiliary packet generators. The packet generators convert the packet field inputs to the auxiliary packet stream format.

The packet generator propagates backpressure from the output ready signal to the input ready signal. The generator asserts the input valid signal when a packet is ready to be transmitted. The input valid signal remains asserted until the end of the packet and the generator receives a ready acknowledgment.
