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. | (temp.vsm,31): Could not open VHDL file 'xenable4.vli'. | (temp.vsm,31): Unrecognized component type XENABLE4, instance name $1I1\$1I37\D_EN. Module ignored. | (temp.vsm,34): Could not open VHDL file 'xenable4.vli'. | (temp.vsm,34): Unrecognized component type XENABLE4, instance name $1I1\$1I37\CE_EN.

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)
