Writes an AMD Vivado™ Design Suite logic analyzer probes file containing ILA debug cores and signal probes added to the current design. The debug probes data file typically has a .ltx file extension.

ILA cores are added to the design using the create_debug_core command. ILA probes are added to the design using the create_debug_port command, and connected to nets in your design using the connect_debug_port command.

The specific information and use of the debug probes file is described in the Vivado Design Suite User Guide: Vivado Programming and Debugging (UG908).


-cell <arg> - (Optional) Specify the hierarchical name of a reconfigurable partition cell to export a partial probe file.

-force - (Optional) Overwrite the specified file if it already exists.

-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 file name of the debug probes file to write.

Note: If the path is not specified as part of the file name, the file will be written into the current working directory, or the directory from which the tool was launched.


The following example write a debug probe file from the current design:

write_debug_probes C:/Data/designProbes.ltx
