Problem Title:
XSimMake, XDraw:  "Could not access Sheet 1 of SCHEMATIC <top>."
Powerview 5.3.2



Problem Description:

ERROR MESSAGE:	Writing new simulation schematic. Please wait....
		LIST OF ERRORS FOUND for XDRAW
		--------------------------------
		ERROR 5: Could not access Sheet 1 of SCHEMATIC <top>.
		1 Errors and 0 Warnings occurred during processing.


		ERROR 7: Command [xdraw -i <top> -o s<top> -a s<top> ]
		failed to execute properly.


When running XSimMake to create a functional simulation network, XDraw will
be used to redraw the design schematics.  In the case where the there are no
special components, only the top level schematic will be redrawn.

PROBLEM:  When trying to run XSimMake functionally on a design created with
Powerview V5.3.2 or V6.0, the version of the schematic is 5.1.	XDraw thinks
the schematic is corrupted.

To verify this, look at the XDRAW.OUT file.  The following is an example of
what XDRAW will report:

		File <top> has been corrupted.
		========> V 51
		Line 1 *** Error #35 ***
		primary:<top>.1 read

CAUSE:	XDraw was compiled with older versions of the Viewlogic tool
libraries which do not recognize version 5.1 schematics.


Solution 1:

Because the Powerview tools can use schematics created using previous
versions, the V 51 line can be changed in the schematics and symbols for
the design being processed.

After copying all the schematics and symbols to a backup directory, modify
the schematics and symbols in the sch and sym sub-directories in the
following manner:

--- first three lines of schematic before change ---

	V 51
	K 165102488100 mytest
	Y 0

----------------------------------------------------

--- first three lines of schematic after change ----

	V 50
	K 165102488100 mytest
	Y 0

----------------------------------------------------

Then, to ensure that the changes will effect future processing, remove all
the files located in the wir sub-directory and run the Viewlogic check
program to recreate them.

	Example:  check -p mytest
