I have opened the synthesized design and open schematic, then zoomed to some part of the schematic. If I right-click and select "Save as PDF file" and give a specific location for saving the PDF file other than default and clicked on OK, this returns the following in the TCL console and does not create the PDF file:
write_schematic -format pdf -orientation landscape -scope visible C:\Users\user1\Desktop\schematic.pdf
In Vivado 2013.2, the path is not being escaped correctly and the backslashes are treated as escape characters in the Tcl interpreter.
To work around this issue, you can type the command in the TCL console for saving the PDF file at a specifc location.
write_schematic -format pdf -orientation landscape -scope visible C:/Users/user1/Documents/test/new
This issue has been fixed in has been fixed in Vivado Design Suite 2013.3.
