    Tracks random packets for formally verifying FIFOs

    Tracks random packets for formally verifying FIFOs

    This ensures that when some data enters the FIFO, it will always be dequeued after the correct number of elements. So essentially we are verifying data integrity. Note that this does not imply that the FIFO has no bugs since e.g., a FIFO that never allows elements to be enqueued would easily pass our assertions.

    This module was inspired by the MagicPacketTracker used in the evaluation of the following paper: Mann, Makai, and Clark Barrett. "Partial order reduction for deep bug finding in synchronous hardware.", CAV'20.
