Why are there back annotation simulation mismatches when simulating a reloadable DA FIR?

Solution

The problem is that there are errors on the RFD initially, which cause a mismatch on the valid out and data outputs of the same block. The errors are seen in short little bursts, then the simulation gets back on track again.
