Notes:
1. If FIFO18 is constrained to FIFO18_X#Y#, then RAMB18 can not be constrained to RAMB18_X#Y# since the same location would be
2. If a FIFO18 is constrained to FIFO18_X#Y#, corresponding to the lower RAMB18_X#Y# of the RAMB18 pair, a RAMB18 can be

Setting determines the difference
between FULL and ALMOSTFULL
conditions. Must be set using
hexadecimal notation.
Setting determines the difference
between EMPTY and ALMOSTEMPTY
conditions. Must be set using
hexadecimal notation.
If TRUE, the first word written into the
empty FIFO appears at the FIFO output
without RDEN asserted.
For multirate (asynchronous) FIFO, must
be set to 1.
For synchronous FIFO, DO_REG must be
set to 0 for flags and data to follow a
standard synchronous FIFO operation.
When DO_REG is set to 1, effectively a
pipeline register is added to the output of
the synchronous FIFO. Data then has a
one clock cycle latency. However, the
clock-to-out timing is improved.
Sets the location of the FIFO18 or FIFO36.
When set to TRUE, ties WRCLK and
RDCLK together.
When set to TRUE, FWFT must be
FALSE.
When set to FALSE, DO_REG must be 1.
