An approach and tool integrate cyber-physical systems design based on the function-behavior-state (FBS) methodology where multi-domain simulation models capturing both the behavioral and structural aspects of a system are automatically generated from its functional description. The approach focuses on simulation-enabled FBS models using automatic and context-sensitive mappings of functional basis elementary functions to simulation components described in physical modeling languages. Potentially beneficial process loops are recognized and inserted in the functional model.

Context-based synthesis of simulation models from functional models of cyber-physical systems

A method for performing time-slack pipeline balancing for multi/many-core programmable logic controllers includes performing a runtime analysis of a plurality of pipeline stages of a program for a multi/many-core programmable logic controller (PLC) while the program is being executed, and of a plurality of system services, to compile a profile of performance statistics of the PLC program and the system services, calculating a time slack for each of the plurality of pipeline stages of the PLC program using the profile of performance statistics, and for all pipeline stages except a longest stage, donating the time slack of each pipeline stage to an operating system of the PLC. Donating the time slack of each pipeline stage includes generating donor code that includes a set of instructions that free a processor core for a given pipeline stage for a time period identified as the time slack period.
