val create : ?overflow_check:Base.bool -> ?showahead:Base.bool -> ?underflow_check:Base.bool -> ?build_mode:Hardcaml.Build_mode.t -> ?scope:Hardcaml.Scope.t -> ?fifo_memory_type:Hardcaml_xilinx__.Fifo_memory_type.t -> Base.unit -> capacity:Base.int -> clock:Hardcaml.Signal.t -> clear:Hardcaml.Signal.t -> wr:Hardcaml.Signal.t -> d:Hardcaml.Signal.t -> rd:Hardcaml.Signal.t -> Hardcaml.Signal.t Hardcaml.Fifo.t

Create a synchronous FIFO with the given capacity. If build_mode is Simulation a hardcaml model is generated (note, though, the model is synthesizable). Otherwise a XPM primitive FIFO is instantiated.

If the overflow_check (resp underflow_check)) logic is enabled a write will not occur when the fifo is full (resp read when empty).

showahead reduces the fifo read latency from 1 to 0 cycles relative to rd.
