Name Description
[-force] Overwrite existing design checkpoint and stub files
[-keep] Keep the temporary directory and project
[-verbose] Print verbose messaging
[-quiet] Ignore command errors
<file> The Block Design file to write a synthesized checkpoint for


Runs synthesis for a block design (.bd), integrates the design along with any needed sub-designs (e.g. out-of-context synthesized IP), and writes out a single design checkpoint (.dcp) of the entire synthesized design, as well as HDL stub files, for use in other synthesis tools. The output files will be placed in the same directory as the source BD file.


-force - (Optional) Overwrite any existing design checkpoint and stub files of the same name.

-keep - (Optional) Keep the temporary directory and project after export_bd_synth has finished.

-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.

<file> - (Required) The block design file (.bd) from which to export a synthesized checkpoint.


The following command will generate a synthesis checkpoint, with stub files, for the specified block design:

export_bd_synth [get_files block_1.bd]
