Module Hardcaml_xilinx.Ram_port_with_clearSource

Statemachine for clearing a RAM via one of it's ports.

Sourcetype 'a t = {
  1. port : 'a Ram_port.t;
  2. clear_busy : 'a;
}

This wraps a Ram_port.t with a small state machine that on clear sets all memory location values to the clear_to value. While the memory is being cleared, the output clear_busy will be high. Writes and reads while in this state will be ignored.

The port signals require an extra mutliplexer delay for this function.

Note that use of other ports on the RAM for writing is discouraged during the clear operation. For maximum safety one can guard the write enable to the other port with

{other_port.write_enable &: ~:port_with_clear.clear_busy}

include Base.Equal.S1 with type 'a t := 'a t
Sourceval port_names : Base.string t

RTL names specified in the interface definition - commonly also the OCaml field name.

Sourceval port_widths : Base.int t

Bit widths specified in the interface definition.

Sourceval const : 'a -> 'a t

const x sets each port to x

Sourcetype tag
Sourceval tags : tag t
Sourceval to_alist : 'a t -> (tag * 'a) Base.list

Create association list indexed by tag.

Sourceval of_alist : (tag * 'a) Base.list -> 'a t

Create interface from association list indexed by tag.

Sourceval sum_of_port_widths : Base.int

Sum of all port widths specified in the interface definition.

Sourceval offsets : ?rev:Base.bool -> Base.unit -> Base.int t

Offset of each field within the interface. The first field is placed at the least significant bit, unless the rev argument is true.

Sourceval of_interface_list : 'a t Base.list -> 'a Base.list t

Take a list of interfaces and produce a single interface where each field is a list.

Sourceval to_interface_list : 'a Base.list t -> 'a t Base.list

Create a list of interfaces from a single interface where each field is a list. Raises if all lists don't have the same length.

Sourcemodule All (M : Base.Monad.S) : sig ... end

Similar to Monad.all for lists -- combine and lift the monads to outside the interface.

Sourceval or_error_all : 'a Base.Or_error.t t -> 'a t Base.Or_error.t

Equivalent to All(Or_error).all. This is made a special case for convenience.

Sourcemodule type Comb = sig ... end
Sourcemodule Of_bits : Comb with type comb = Hardcaml.Bits.t
Sourcemodule Of_signal : sig ... end
Sourcemodule Of_always : sig ... end

Helper functions to ease usage of the Always API when working with interfaces.
