has the path to the XC3000 library. Select
to modify the Library Search Order.
Select the modified library. In the Path field, change the path so it
points to the XC9000 library directory. Click
Select this library again. Click the
button until it is
below the primary library and any user-created libraries. Click
Save the changes in the Project Manager.
When writing the EDIF file from ViewDraw for subsequent
implementation in an existing Xilinx project, you must keep the same
filename and project directory.
In the Design Manager window, select
. This brings up the New Version dialog box, shown in
the "New Version Dialog Box" figure. The version name incre-
ments by default.
Change the name of this version, if desired, and add any
comments for this version. Click
to create this new version.
Using Viewlogic Powerview on Workstations
In this example, we are converting a Viewlogic schematic originally
implemented using the XC3000 library into a schematic targeting the
Copy your existing schematic file(s) from the project directory
used for the other device family (XC3000) into the project direc-
tory you want to use for the new target library (XC9000). For
cp proj7000/sch/design1.1 proj9000/sch
Use the Viewlogic project management facility (or edit the view-
draw.ini file) in your XC9000 project directory to list both the new
library (XC9000) and the other family's library (XC3000) in the
Search Order. For example, if you are converting an XC3000
design to XC9000, your viewdraw.ini file would contain the
following two lines:
