Problem Title:
Foundation: Importing a Viewlogic design with a user library


Problem Description:
User-created macros for most Viewlogic designs reside in the
project directory, or "primary" library.  However, some users
or companies store frequently-used macros in a separate
directory (referred to here as a "non-primary user library")
This directory is referenced in the viewdraw.ini as a
read-only [r] or read-write [w] library.

When importing a Viewlogic design, the Foundation tools look
only in the primary library for user-created macros.  If the
macro is not found in the primary library, a warning is
issued and there will be a blank space in the design.

How can this be avoided?


Solution 1:

The solution is to import the required macro schematics from
the non-primary user library before importing the main
design.

Example:  The main design is C:\PROSER\TOP, and it uses
macros called 7BIT_REG and MULT_8X8 from C:\MYLIBS\LIB1.

1. Start the Foundation Schematic Editor and select File ->
   Import ViewLogic Schematic.
2. Browse to C:\MYLIBS\LIB1\SCH and use CTRL-click to select
   7BIT_REG.1 and MULT_8X8.1.  Click OK to import these
   schematics.
3. Select File -> Import ViewLogic Schematic again.
4. Browse to C:\PROSER\TOP\SCH, and select TOP.1.  Click OK
   to import the design.
