hardcaml_waveterm v0.13.0 · OCaml Package

A waveform is a mutable value that represents the outcome of a simulation; it holds a time series of values for a number of ports. The waveform is updated by running the simulation.

type t

val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t

val create : ('i, 'o) Hardcaml.Cyclesim.t -> t * ('i, 'o) Hardcaml.Cyclesim.t

Create waveform. Returns a new simulation object that side effects the waveform.

  ?display_rules:Display_rules.t ->
  ?display_width:Base.Int.t ->

  'a

Waveform configuration options.

display_rules see Display_rules. A waveform may be constructed once and displayed multiple times with differing options.

wave_height sets the number of rows each wave is displayed with.

<0 an exception is raised
0 2 lines per wave. This show transitions but not the data for multi-bit signals.
1 2 lines for binary data, 3 lines for multi-bit data. This is the default and most compact view.
n (n+1) lines per wave.

wave_width sets the number of chars used to render each clock cycle.

n>=0 ((n+1)*2) characters per cycle. This ensures that the clock is properly rendered when n=0. The default of 3 allows up to 7 chars per cycle to be rendered to represent data values in the waveform.

n<0 (-n) cycles per character. Characters in the waveform within which multiple transitions occur are displayed with a double veritical bar.

display_width and display_height simply set the overall size of the displayed waveform. An auto scaling routine assigns approximately 1/3 of the display for the signals and values windows. The default size is 70 character wide and 20 high. The minimum size is 7 characters wide and 3 high and an exception is raise otherwise.

val sort_ports_and_formats : 
  t ->
  Display_rules.t Base.Option.t ->
  Wave.t Base.Array.t

val to_string : (t -> Base.String.t) with_options

Convert waveform to a string.

val print : (?channel:Stdio.Out_channel.t -> t -> Base.Unit.t) with_options

Print waveform to channel default stdout.
