Module Hardcaml_waveterm.Waveform

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

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.

Convert waveform to a string.

Print waveform to channel default stdout.
