End-to-end path delay estimation in embedded software involving heterogeneous models

Extending model-based Non-Functional Property (NFP) analysis approaches to Embedded Software Engineering (ESE) projects cutting across heterogeneous modeling domains is an emerging research challenge. Towards this direction, a generic workflow for timing validation and a methodology for synchronization of timing attributes (before performing a timing analysis) in ESE projects developed using heterogeneous modeling domains is proposed in this paper. An experimental evaluation of the proposed approach, in a state-of-the-art timing analysis tool, using a real life, light-weight ESE project, developed using Unified Modeling Language (UML) and Simulink is presented.
