Abstract

A computer-based design framework for collaborative design of a product by distributed design team members. The design framework comprises: a virtual database management system, which receives data from a plurality of distinct sources and creates a single relational database interface to each of the distinct sources; software code associated with the virtual database management system for mapping various informational structures utilized by the distinct sources to a common XML syntax; and additional logic associated with the virtual database management system that provides publishing rules for extracting information on demand and publishing the extracted information in a format recognized by a requestor of the information. When the product is a system on a chip (SOC) a special set of functions are generated that enable platform-independent application and services exchange utilizing XML wrapped data, service, and applications.

2. The computer-based design framework of claim 1, wherein each SOCML function is coded utilizing design and analysis java applications that are translated into XML, wherein said XML acts as a platform-independent wrapper for said SOCML functions.

3. The computer-based design framework of claim 2, wherein each of said design teams operates on a particular sub-component of the design of said product including system design, application development, and manufacturing.

4. The computer-based design framework of claim 3, wherein said publishing rules includes transformation rules based on extensible Style sheet Language (XSL), said framework further comprising program code for providing a design team member and other personnel with output from said design process via XSL style sheets and XSLT transformers, which manipulate data from said SOCML database.

5. The computer-based design framework of claim 4, further comprising program code for exporting design information to industry standard IC design computer aided design tools.

21. The computer-based design framework of claim 1, wherein said functional components include a SOCML database, a SOCML simulator, a SOCML synthesis and timing analysis component, and a SOCML database exchange manager.

6. A method for distributed, collaborative design of a product in a computer-network based design environment, said method comprising:

establishing a network-accessible design framework that enables remote access to individual members or groups of a design team;

normalizing a set of tools within said design framework for utilization by each of said individual members or groups, wherein said tools are available via said network;

providing secured access to said design framework by said individual members and groups from a terminal connected to said network; and

providing, via said design framework and said terminals, real-time collaborative design of said product design with platform-independent application and service exchange utilizing eXtensible Markup Language (XML) wrapped data, service and applications;

wherein said product is a system-on-a chip (SOC), further comprising enabling said collaborative features of said design framework utilizing a system on a chip extensible markup language (SOCML) that allows cross-interaction between different design teams utilizing different tools, said SOCML providing a specific XML schema to define System-on-a-Chip design data and a standard for storing and transporting SOC specification and design data.

providing the automated exchange of design data via XML functionality, wherein a set of rules defining XML tags are utilized to define a structure, format, and content of design data components that are exchanged;

providing processing and searching of data utilizing XML-based search tools that use data structure and meta data; and

enabling both local and remote processing of said data.

8. The method of claim 6, wherein said enabling comprises:

defining elements that may exist in a SOCML document utilizing document type definition (DTD);

setting corresponding attributes of said elements, nesting of said elements, and the order of which said elements are defined in SOCML; and

selecting which XML design files adhering to SOC document type definitions constitute SOCML.

9. The method of claim 6, further comprising:

receiving architectural, functional, and performance specification in hardware description language(HDL);
