  • Publication number: 20040107214
    Abstract: A system for customizing a design portfolio for an IC product. An IP library management server allows IP providers to upload IP libraries and subsequently verify and sort the uploaded IP libraries. A technology document server allows a foundry to upload technology documents and verify and sort the uploaded technology document. A database stores the verified technology documents, IP libraries, and meta information associated therewith. A design portfolio management server provides a terminal user the verified technology documents and IP libraries for creation of a customized design portfolio thereby and further monitoring the customized design portfolio to send notification when the portfolio status changes.
