global basis for the entire scenario. In other words, any scenario action that modifies line
traffic only affects the traffic flowing in the direction established at the top of the
scenario, in the Scenario Properties. Scenario events can be monitored in either direction,
and therefore the parameters for events provide the ability to specify the intended
direction for monitoring traffic for that event.

during a SATA frame, the port stops reading data from the FIFO and generates HOLDA.
The HOLD propagates through the bus engine and eventually goes to the other device,
