There is a rapidly growing need for tools for the design and synthesis of electronic systems and multi-device circuits: to support greater clock speeds; packaging densities and circuit complexity; to enable designers to rapidly create and compare alternative design concepts; to eliminate multiple redesign cycles; and to enable reuse of prior design knowledge. There no CAE tools commercially available today that meet the above needy based on eight years of previous, successful world in investigating and developing such tools, Omniview's project team members have developed the concept of synthesis by-composition as the one mod likely to succeed the architecture of the proposed design & synthesis system based on this concept is composed of five major subsystems a friendly user interface; a design synthesis engine; a design knowledge repository; a family of design advisor to design synthesis engine; a design knowledge repository; a family of design advisors to design space exploration, packaging, reliability, to ability, and manufacturability/cost; and a design partitioning expert system output can also be interfaced to available CAE/CAD tools, e g, PC layout Omniview's Phase I technical objectives are to demonstrate the feasibility of its overall system concept, to evaluate new subsystem concepts for design partioning, and to complete the system architecture and specifications, leading to a Phase II implementation and demonstration plan that is highly likely to succeed Omniview' project team is one of the mod experienced in the world in this specific area, based on its 20 man-year of direct, prior work its 20-plus publications, including six by the principal investigator the team also has 30 years of additional, relevant, experience in BHDL, simulation, high-density electronics packaging, testability, etc.
