You can then:
- Select predefined options from the pull down menu.
- Enable or disable some options with a check box.
- Type a user-defined value for options with a text entry field.
- Use the file browser to specify a file for options accepting a file name and path.
- Insert a custom Tcl script (called a hook script) before and after each
step in the implementation process (tcl.pre and tcl.post). This lets you perform specific tasks either
before or after each implementation step (for example, generating a
timing report before and after Place Design to compare timing
For more information on defining Tcl hook scripts, see Vivado Design Suite User Guide: Using Tcl Scripting (UG894).
Relative paths in the tcl.pre and tcl.post scripts are relative to the appropriate run directory of the project they are applied to: <project>/<project.runs>/<run_name>.
You can use the DIRECTORY property of the current project or current run to define the relative paths in your scripts:
get_property DIRECTORY [current_project] get_property DIRECTORY [current_run]
- Click OK to save the new strategy.
The new strategy is listed under User Defined Strategy. The Vivado tools save user-defined strategies to the following locations:
- Linux OS: $HOME/.Xilinx/Vivado/strategies
- Windows: C:\Users\<username>\AppData\Roaming\Xilinx\Vivado\strategies
