Suggestion objects are stored in binary: as a consequence, the only way to read
the suggestion is to load the design, read the suggestions, and run
report_qor_suggestions. Support for viewing and executing
suggestions in Tcl is available for users who do not wish to use the object flow.
To write out suggestions in Tcl, use the following command:
write_qor_suggestions -tcl_output_dir <outputDir>
Running this command outputs one or more Tcl files to the stated directory. This option is not available in the Vivado IDE.
For the Tcl scripts generated for the implementation commands, add them to implementation
runs using the Tcl Pre or Post hooks, typically before opt_design is best to use. They can be
read using Tcl source command in a non project flow. For the synthesis Tcl scripts, they must
be added to the constraints set in project mode (update the file filter to Tcl in order to see
them), or in non project mode accessed using
read_xdc -unmanaged <Tcl
When the objects are in Tcl, it is the user's responsibility to maintain the Tcl to remove objects that are no longer required and apply only the suggestions that they want to apply. Any newly generated Tcl scripts will need to be appended to the existing Tcl scripts.
Suggestions that are entered using Tcl are no longer reported by
