Description
Warning: [200-942] %s loops have FIFO
operations on variable '%s'.
This message reports that the code is violating loop merging optimization rules.
Explanation
Loops cannot be merged when they contain FIFO reads. Merging changes the order of the reads. Reads from a FIFO or FIFO interface must always be in sequence.
Solution
Loops cannot be merged when they contain FIFO accesses because of sequential access.
