Description
Writes a hardware definition (.hwdef) file for use in the software development tools (SDK).
Each BD and HIP generates a .hwdef file. Write_hwdef merges all the files into a single container. This command is run automatically by the Vivado Design Suite when generating the output products for a top-level design that includes a block design with an embedded processor like MicroBlaze, or Zynq-7000 SoC. Block designs are created in the IP integrator of the Vivado Design Suite with the create_bd_design command.
The write_hwdef command is run after place_design and creates a hardware container file with .hwdef extension. The container file includes device metadata and hardware design files.
The write_hwdef command returns nothing if successful, or an error if the command fails.
Arguments
-force - (Optional) Overwrite and existing hardware definition file if one exists. If this option is not specified, then the Vivado Design Suite will not overwrite an existing file.
-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<file> - (Required) Specify the name of the hardware definition file. The file can include the path and file extension. The default file extension of .hwdef is used if an extension is not specified.
Examples
