2012.2 Vivado - ERROR: [#UNDEF] Error while reading WCFG file 'C:path owave1.wcfg'.

Description

I have saved a simulation waveform (WCFG) file. 

Now, when I re-launch simulation using the same waveform, I receive an error and it does not appear that the correct path is being used.

For example:

My waveform file is saved at: C:\path\to\wave1.wcfg

When I re-launch simulation I see the following messages:

----------------------------------------------------------------------
xsim my_design_behav -tclbatch my_design_behav.tcl -view C:\path\to\wav1.wcfg -logmy_design_behav.log

open_wave_config C:path owave1.wcfg
------------------------------------------------------------------------------------------

ERROR: [#UNDEF] Error while reading WCFG file 'C:path owave1.wcfg'.

Solution

This issue occurs in Vivado Design Suite 2012.2 on Windows OS or in projects which contain spaces in the path to the .wcfg file.

The directory to the wcfg file is not being properly escaped.  

Back slash characters separating directory structure are being treated as escape characters, and spaces are treated as indicating the end of the file name.

The wcfg file still exists and can be opened after launching the simulator.

This issue has been corrected in Vivado Design Suite 2012.3.
