The source command lets you manually load Tcl script files into the Vivado tools:
> specifies both the name
of the file, as well as the relative or absolute path to the file. If no path is
specified as part of the file name, then the Vivado tools look for
the file in the working directory, or the directory from which the Vivado Design Suite was launched.
Within the Vivado IDE you can also source a Tcl script from the menu command.
By default, the source command echoes each line of the file to the Tcl console. This can be
prevented by using the
-notrace option, which is specific to the
Vivado Tcl interpreter:
source <filename> -notrace
