Abstract
A first in, first out (FIFO) queue includes logic to provide detection of operational errors in the FIFO queue. The FIFO queue includes entries to store data written to the FIFO queue and signature bits, each signature bit corresponding to one of the entries. A test pattern and a read signature register includes a number of bits greater than a depth of the FIFO queue. A comparator compares the test pattern to the read signature register and output an error signal indicating whether the test pattern matches the read signature register.
