CIS Admin Tool for OrCAD CIS

If your OrCAD Capture CIS designers work in a multi-user networked environment, you can leverage CIS functionality for easier management of your group's part and footprint libraries and files you can browse. Placing libraries and files in a designated location forces all engineers to pull information from a central source. This not only promotes data integrity, since all users are getting part information from a common source, but also eases the burden of administrating libraries.
