VIEWSIM: How to fix 'Could not open VHDL file...', 'Unrecognized component...'

Description

When invoking ViewSim on a design, errors similar to the following may
occur:

=================
| Typical delays in use.
| All delays scaled by 1.
| (temp.vsm,28): Could not open VHDL file 'xfshre.vli'.
| (temp.vsm,28): Unrecognized component type XFSHRE, instance name $1I1\$1I37\CLR_CHK.
Module ignored.

This is normally due to the local viewdraw.ini/project manager refering to the wrong version
of the builtin library. Be sure the viewdraw.ini file is pointing to the
one located in the %XILINX/Viewlogic UNIFIED subdirectory. Do not use the
builtin library supplied by Viewlogic. Here is the libraries section from a
sample viewdraw.ini file:

DIR [p] . (primary)
DIR [rm] C:\PROSER\UNIFIED\XC4000 (XC4000)
DIR [rm] C:\PROSER\UNIFIED\XBLOX (XBLOX)
DIR [rm] C:\PROSER\UNIFIED\BUILTIN (BUILTIN)
DIR [rm] C:\PROSER\UNIFIED\XBUILTIN (XBUILTIN)
