Figure 3–18. Atlantic Interface Timing—Slave Source to Master Sink
Notes to
(1) Slave source indicates that data is available (either threshold words available, or EOP).
(2) Master sink begins reading data.
(3) Master sink decides to stop reading the data for one clock cycle. val remains asserted and data, sop, and eop hold their current
(4)
(5) Master sink continues to read data, validates data with val.
(6) Slave source cannot supply any more data, so deasserts val.
(7) Master sink goes idle until dav is re-asserted.

(7) Slave sink indicates it still has space, but the master source has run out of data.

values.
Slave source indicates that it has less than threshold words available. The master sink can continue to read data until it detects val
deasserted.
Slave sink indicates it has space for at least threshold words.
Slave sink indicates it has space for threshold words. Master source can continue to send data, but must ensure that the slave sink does
not overflow.
Slave sink indicates it has space for at least threshold words.

Signal Naming Convention
When you include an Atlantic interface in a design, the IP Toolbench generates the
signal names, which are prefixed by <port name>_, such as, b1_ena, b1_val,
b2_ena, b2_val.
