Figure 5–12. Avalon-ST Sink Block with All Signals Enabled
The Avalon-ST Source block defines a collection of ports for connection to an
SOPC Builder system when your design functions as an Avalon-ST source.
For information about the Avalon-ST interface, refer to the
Specifications.

Data input bus.
Data valid signal that indicates the validity of the output data signals.
Data output ready signal. Indicates that the source can accept data.
This signal is available when the Use startofpacket parameter is on and marks the active
cycle containing the start of the packet.
This signal is available when the Use endofpacket parameter is on and marks the active
cycle containing the end of the packet.
This signal is available when Use empty is turned on and the bit width is greater than the
symbol width. It specifies how many of the symbols in a packet are empty. For example,
a 32-bit wide bus with 8-bit symbols can have an empty value from 0 to 3.
