  3. Concurrency Modeling Cont. • Advantages of Concurrency Modeling • Better Performance • Lower Power Dissipation • Higher Reuse • Pitfalls of Concurrency • Intermittent & Catastrophic failures • Not a Traditional Coding Style • Poor Specification – Large Integration Time Example of Concurrency Failures • Denver Airport Baggage System • Airplane Software Glitch

  4. Start With High Level System Specification Provide Annotation to Avoid Problem Recurrence in Future Specs Identify Concurrent Processes from System Specification Model Process Interaction with FSP Analyze the System for any Possible Deadlock/Livelock Add Concurrency Constructs as Needed Proceed to Design Phase Concurrency Modeling

  5. Concurrency Modeling Cont. • Concurrency Modeling will ensure that there are no deadloack/livelocks in a system • Easier & quicker to integrate components into a subsystem, and a subsystem into a system • Concurrency modeling at an early stage will speed up system modeling and analysis • Enhanced Component Reuse via subsystem Design Patterns

  6. Component Modeling • Component Modeling with MLDesigner • Abstract Component Modeling • Maturity • First release was in Year 2000 • Includes numerous libraries, 2000+ design blocks and 250+ executable demo systems

  12. MLD Design Methodology Cont.

  13. Companies Using MLD

  14. MLD Discussion Cont.

  15. MLD Discussion Cont. • Uses ptlang and generates organized C++ code • Supports UML state charts and UML FSM’s • Supports Tcl/tk and Ptcl. • Unifies BONeS, SPW, MATLAB, and COSSAP • MLD3 expected to support synthesizable SystemC code generation if all primitives are described in DE and FSM’s

  16. MLD Design Methodology • Define problem space • Questions to be answered • Identify key contributions to performance (components, channels, events) • Develop an initial design model • Define topology (components, HW/SW partitioning) and key events between components • Define the levels of abstraction required for each component • Define data structures to support modeling and analysis • Build abstract models of architecture and functionality

  17. MLD Design Methodology Cont. • Execute and validate model • Compute and analyze performance measures • Compare to previous measurements of actual systems • Add detail to model • Add functional details to increase model fidelity • Test • Iterate the detail cycle (4) as needed • Analyze and perform tradeoff studies • Designate an executable specification
