Viewsynthesis: Symbol precompiled_xc3000:FDPE cannot be found

Problem Title:
Viewsynthesis:  Symbol precompiled_xc3000:FDPE cannot be found


Problem Description:
When synthesizing a design with Viewsynthesis, you may encounter the
following error:

Symbol precompiled_xc3000:FDPE cannot be found.

The symbol FDPE is not part of the Unified XC3000 library, as the flip-flops
in the XC3000 architecture do not support asynchronous Preset.	However,
Viewsynthesis is able to emulate the asynchronous preset flip-flop, and does
so with the Macro called FDPE from their own Precompiled_XC3000 library.


Solution 1:

You must add the Precompiled_xc3000 library to your viewdraw.ini file,
immediately following the Unified XC3000 library.

Example:

<viewlogic_path>\standard\syn\pre\xc3000 (precompiled_xc3000)
