Creates a new wave config


create_wave_config [‑quiet] [‑verbose] [<name>]


The new wave config.


Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<name>] Creates a new wave configuration of the specified name, or a default name if no name given. A new wave window showing that WCFG is also created and made the current wave window




Create a new wave configuration object in the current simulation, and open the waveform configuration in the Vivado® IDE. This will make the new wave configuration object the current wave configuration.

In the Vivado® simulator GUI, you can work with a waveform to analyze your design and debug your code. The Wave Config file contains the list of wave objects (signals, dividers, groups, virtual buses) to display, and their display properties, plus markers. A wave configuration displays with top-level HDL objects, and can be further populated using commands like add_wave and add_wave_divider. Any changes made to a wave configuration can be saved to a Wave Config file with the save_wave_config command.

This command returns the name of the waveform configuration created, or an error if it fails.


-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<name> - (Optional) The name to give to the wave configuration object. If no <name> is specified, an untitled waveform configuration will be created, called "Untitled #", where # represents a numerical sequence beginning at 1.


The following example creates a new wave configuration object with the specified name:
