Heterogeneous co-simulation for embedded and cyber-physical systems design

Abstract

The growing complexity of embedded and cyber-physical systems makes the design of all system components from scratch increasingly impractical. Consequently, already from early stages of a design flow, designers rely on prior experience, which comes in the form of legacy code or third-party intellectual property (IP) blocks. Current approaches partly address the co-simulation problem for specific scenarios in an ad hoc style. This work suggests a general method for co-simulation of heterogeneous IPs with a system modeling and simulation framework. The external IPs can be integrated as high-level models running in an external simulator or as software- and hardware-in-the-loop simulation with minimal effort. Examples of co-simulation scenarios for wrapping models with different semantics are presented together with their practical usage in two case studies. The presented method is also used to formulate a refinement-by-replacement workflow for IP-based system design.

Review of Modeling and Simulation Methods for Cyber Physical Power System

“…It is necessary to provide a simulation platform for the dynamic study of the impact of physical power grid fault on the communication network and the impact of communication system fault on the power system. According to the different simulation schemes (Hopkinson et al, 2006;Hua et al, 2011Hua et al, , 2012Celli et al, 2014;Lai et al, 2014;Tang et al, 2016;Sun et al, 2019;Attarzadeh-Niaki and Sander, 2020), the CPPS simulation methods can be divided into three categories, i.e., cyber physical co-simulation, semi-physical simulation, embedded simulation.…”

Testing the Verification and Validation Capability of a DCP-Based Interface for Distributed Real-Time Applications

“…In the search for language-and platform-independent solutions, studies such as [15], which presents a co-simulation framework based on the Functional Mock-up Interface (FMI), and [16], which utilizes the High-Level Architecture (HLA) standard, are noteworthy. The authors of [5] also propose an architecture aiming to avoid ad hoc approaches, focusing on guaranteeing IP protection. However, their major drawback is that they have not considered the integration of real-time systems or hardware-in-the-loop simulations.…”

“…Testing the correct interaction between these elements at an early stage of the development phase facilitates the process of validation and verification of them. However, as stated in [5], it is common to solve the challenge of linking such elements using ad hoc methods.…”

Research on co-simulation of multi-resolution models based on HLA

“…It clearly defines the interface specifications of various simulation models, which provides a framework for the development and implementation of distributed interactive simulation applications. 18,19 For example, Possik et al 20 presented the method to integrate different discrete event simulations components, using HLA evolved standard, business process model and notation, and Jaamsim. Gorecki et al 21,22 established a multicomponent distributed modeling and simulation framework platform for the smart production system and realized the interconnection of solar panel entities established in several countries under the frame of a global simulation managed by HLA.…”
