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
XC9000 library.
1.
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
example:
cp proj7000/sch/design1.1 proj9000/sch
2.
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:
DIR [r]
installation_path/viewlog/data/xc9000
(xc9000)
