  8. Motivation for building a DFM frameworkSimulation-based Design General Overview • “Systems Approach” to product realization -- organizing the “smorgasbord” • Capturing mutual interaction amongst design, manufacturing, assembly, testing, packaging etc. related activities • Building product and associated process models • Creating smart configurations – adaptable to changing technology and business needs • Reduce cycle time and possibilities of redesign • Capturing activity specific knowledge and utilize it for enhancing related activities and tasks • Learning from today’s experience to improve performance tomorrow – Intelligent Systems

  9.

  11. Core Ingredients of a DFM Framework1. Electronics Product Design Model • Need of an Integrated Design Model • Ability to support different dimensions of product design • Functional Model • Part - Assembly Structure • Configuration Management • Requirements Specification • Formal data specification for higher fidelity across engineering domains • Semantically rich in content and coverage – ability to expand to the ever rising complication in product and process data structure

  12. Core Ingredients of a DFM FrameworkChallenges towards an Integrated Design Model Existing Tools Tool A1 Tool An ... Legend Content Coverage Gaps “dumb” information capture (only human-sensible, I.e., not computer-sensible) Example “dumb” figures • Smart Product Model • Building Blocks • Models & meta-models • International standards • Industry specs • Corporate standards • Local customizations • Modeling technologies: • Express, UML, XML, COBs, … Content Semantic Gaps

  13. Core Ingredients of a DFM Framework2. Manufacturing Expertise • Need to capture the expertise of manufacturers • To be able to gather manufacturing knowledge • To be able to represent this genre of knowledge • To be able to use these knowledge sets to guide design decisions • To be able to share this knowledge across enterprise specific manufacturing facilities

  16. Functional Foundation of DFM Framework1. Answering integrated design model challenge • Use of STEP AP210 standard specifications to build the semantically richer and higher fidelity integrated design model

  17. Interconnect Assembly Printed Circuit Assemblies (PCAs/PWAs) Product Enclosure Die/Chip Packaged Part Printed Circuit Substrate (PCBs/PWBs) Die/Chip Package External Interfaces STEP AP 210 (ISO 10303-210) Domain: Electronics Design(ap210.org) ~800 standardized concepts (many applicable to other domains) Development investment: O(100 man-years) over ~10 years

  18. Functional Foundation of DFM Framework2. Answering knowledge capture challenge • Use of Expert Systems Technology • Expert Systems are computer programs to emulate human expertise and take decisions to the best of current knowledge. • Used for problems / scenarios that are complex (abstract, deeply branched decision tree etc.) enough to require human expertise. • Facility to add knowledge • Explanation facility to track the chain of logic – serves as a conformance test

  19. Core Advantages of Expert Systems • Separation of knowledge from control • Better foundational architecture • Ease of maintenance • Ability to add new knowledge and refine functionality • Ability to handle abstraction • Support decision making in the design process in the absence of knowledge – to the best use of as-available information • Trace the tree of design decisions • Ability to track the logical steps in process • Serves as an explanation facility • Used for conformance testing
