  1. Ptolemy-Oriented Structural, Reconfigurable and Heterogeneous Hardware Design, Verification and Synthesis. • Motivation • Complexity, V-deep submicron, low power, high performance& successful completion of ASICs constitute current hardware designs challenges. • Ptolemy concurrency, heterogeneity, hierarchy, portability, distributed modeling, component-based framework, code generation, openness and otherssupport hardware design solutions • Productivity Gap Growth • Ptolemy: A HW design Perspective • Design Lab. • Ptolemy II is first and foremost a laboratory for experimenting with design techniques • Openness • Embedded software & platforms development • Choice of models of computation • Heterogeneous HW • Component Based Design • Actor-Oriented design/Comms. Channels • GUI based design environment • HW Properties of Models of Computations • Continuous Time • Analog • Mixed Signal / Modal & Hybrid Models • CT + FSM = Modal Model • Re-configurability • Discrete Events • Digital • FSM • Control • HW Properties of PTII Architecture • Kernel Package • Clustered Graphs and Hierarchy • Mutation & Concurrency • Actor-Oriented classes • Derivation Invariance • Actor Package concurrent computation • Domain Polymorphism • Reusability • Data Package • Data encapsulation and Polymorphism • Copernicus Package • Code generation • Ptolemy-Hardware Design Solutions & Research Scopes • Higher Level Abstraction • Java modeling & diverse Actor lib. • Domain & data Polymorphism • Expression language • Highly Structural & Hierarchical Component- Based design • Actor lib., Modal modeling • Actor-oriented classes and inheritance • Reconfigurable and Programmable Systems • Mutations • FPGA platform for HW execution • Low- Power design • Low power models of computation & actors • Mixed Signal Systems • Combined analogue and digital systems • Verification • System level and Java modeling • Coverage models of computation • Synthesis • Behavioral synthesis of actor lib. • HW specification synthesis • Past/Current PTII HW efforts status • Mixed HW/SW in DSP • HW/SW mapping & Partitioning • Embedded systems • HW/SW Co-design • Embedded multiprocessing • JHDL Integration • SDF synthesis • Refer to handout for complete references • Influence of PTII Joint collaborations on HW design • Agilent ADS • Mescal Project UC, Berkeley • PeaCE Project, Seoul National University • VisualSim from Mirabilis • Conclusion • Ptolemy II address HW design challenges • Ptolemy II presents a rich platform for HW solutions and research scopes • Ptolemy II has low-entry barrier for HW designers • Author • Mohamed A.
