Problem Title:
XNFPREP: Possible cause of 'ERROR 1303, comma required' on Orcad designs


Problem Description:
In OrCAD, it is legal to give a sheet symbol a name containing
spaces.  If this is done on a Xilinx design, XNFPREP will issue the following er
ror:

   XNFPREP: ERROR 1303: The following problem(s) were found in
      the <design>.xff file; the file could not be processed
      successfully.

      A comma is required on line <line#> of file <design>.xff:
      "HIERG, 1, <filename>, <sheet name>, <filename>.xnf, 0"

Because of the space in the sheet name, the hierarchical prefix
contains spaces.  This is not a legal Xilinx name.


Solution 1:

Change all sheet names to legal Xilinx names (for example,
replace spaces with "_") to avoid this error.
