TRACE will report all of these parameters as T RCKO_DO .
T RCKO_DOR includes T RCKO_DOW , T RCKO_DOPR , and T RCKO_DOPW as well as the B port equivalent timing parameters.
These parameters also apply to synchronous FIFO with DO_REG = 0.
T RCKO_DO includes T RCKO_DOP as well as the B port equivalent timing parameters.
These parameters also apply to multirate (asynchronous) and synchronous FIFO with DO_REG = 1.
T RCKO_FLAGS includes the following parameters: T RCKO_AEMPTY , T RCKO_AFULL , T RCKO_EMPTY , T RCKO_FULL , T RCKO_RDERR , T RCKO_WRERR.
T RCKO_POINTERS includes both T RCKO_RDCOUNT and T RCKO_WRCOUNT.
The ADDR setup and hold must be met when EN is asserted (even when WE is deasserted) . Otherwise, block RAM data corruption is
possible.
9. T RCKO_DI includes both A and B inputs as well as the parity inputs of A and B.
10. T RCO_FLAGS includes the following flags: AEMPTY, AFULL, EMPTY, FULL, RDERR, WRERR, RDCOUNT, and WRCOUNT.
11. The FIFO reset must be asserted for at least three positive clock edges.
12. When using ISE software v12.4 or later, if the RDADDR_COLLISION_HWCONFIG attribute is set to PERFORMANCE or the block RAM is
in single-port operation, then the faster F MAX for WRITE_FIRST/NO_CHANGE modes apply.
