Item Description
H Assume data available indicator defines the data flow within the loop. The arrow indicates
that the data serves as input to the first block in the loop.
If a group of blocks are in a loop, you have to identify which block to execute first. Use the
Assume Data Available indicator to mark the input wire that creates the loop (the feedback
wire).
This input pin uses the output that block 3 produced on the previous scan.
