General Description:
The Virtex-4 User Guide states that the ALMOST_EMPTY flag should deassert after 3 clock cycles once the threshold is reached. The simulation model and hardware do not match this description, and the ALMOST_EMPTY_FLAG does not deassert until 2 more data writes and 3 read clock cycles.
This is the expected behavior in both hardware and simulation. The Virtex-4 User Guide is being corrected to reflect this behavior.
