Problem Title:
Possible cause of Error 'tl2035 the xnf file cannont be read by XEMAKE'


Problem Description:
Processing hierarchical designs under XDM/XEMAKE fails, giving the
following error:

tl2035: The file 'xnf/sub.1', which is needed to build 'top', is missing
	or can not be read by XEMAKE. Verify that this file exists and has
	read access.


Solution 1:

If the xnf files produced by SDT2XNF/WIR2XNF/XNFMERGE are written to a
subdirectory, this problem will occur. XEMAKE gets confused and attempts
to look for the subschematics in that subdirectory. The tutorial UARTTOP
exhibits this problem.

1. Run XEMAKE with the "-r" option (force execution of all commands), or

2. Choose to write out the xnf files produced by SDT2XNF/WIR2XNF/XNFMERGE
   into the current design directory, rather than into a subdirectory.
