Semantics for Rollback-Based Continuous/Discrete Simulation
2008 IEEE International Behavioral Modeling and Simulation Workshop, 2008Modern device trends present greater challenges to design [1] because many of them integrate continuous and discrete sub-systems and therefore their design involves specific global modeling and validation approaches. This paper proposes the operational semantics for rollback-based synchronization model that may be used in continuous/discrete systems ...

A SystemC/Simulink Co-Simulation Framework for Continuous/Discrete-Events Simulation
2006 IEEE International Behavioral Modeling and Simulation Workshop, 2006The increasing complexity of continuous/discrete systems makes their simulation and validation a demanding task for the design of heterogeneous systems. The global validation of these systems requires new techniques offering high abstraction levels and simulation accuracy from a time point of view. The main challenge is the time synchronization and the

Time Discretization in Pedestrian Dynamics Simulations by Discrete-Continuous Model
2021A discretization of time in computer simulation of pedestrian movement is considered. Time step is very influencing on computational performance. But not only quick calculations is a criterion. The other one is a confidence to a simulation result. From both aspects, the discrete-continuous model SigmaEva is considered in the paper. It is shown that low

Combined continuous/discrete simulation
Proceedings of the 18th conference on Winter simulation - WSC '86, 1986Beside from purely discrete event and/or continuous system simulations, there exists yet another simulation methodology that combines both classes of simulations into one. It is often possible to model one and the same system by use of completely different world views.

Codis – A Framework for Continuous/Discrete Systems Co-Simulation
IFAC Proceedings Volumes, 2006Abstract This paper presents CODIS, a co-simulation framework for continuous/discrete systems. Based on a well defined synchronization model and a generic architecture for continuous/discrete simulation models, this framework enables easy specification and automatic generation of simulation models. The supported simulators are Simulink for continuous

Formal Definitions of Simulation Interfaces in a Continuous/Discrete Co-Simulation Tool
Seventeenth IEEE International Workshop on Rapid System Prototyping (RSP'06), 2006Continuous and discrete components may be integrated in diverse embedded systems ranging across defense, medical, communication, and automotive applications. The global validation of these systems requires new validation techniques, the main challenge being the definition of global simulation models able to accommodate the different concepts specific ...

Discrete Simulation of Continuous Systems
2020Finding a discrete system which simulates the behavior of a given continuous system is important in discrete-domain control system design, since the (continuous) plant’s response to a discretized input must be known before a controller can be designed for that plant.

Combined continuous-discrete system simulation with GASP IV
Computers & Operations Research, 1977Abstract GASP IV provides an alternative to the several better known and often used simulation languages, such as GPSS, SIMSCRIPT, and DYNAMO[8, 10, 11, 13, 14]. Whereas GPSS and SIMSCRIPT are discrete change languages and DYNAMO is a continuous change simulator, § GASP IV has the unique capability to perform a combination of both discrete and ...

Parallel synchronization of continuous time discrete event simulators
Proceedings of the 1997 International Conference on Parallel Processing (Cat. No.97TB100162), 2002Mixed-Mode simulation has been generating considerable interest in the simulation community and has continued to grow as an active research area. Traditional mixed-mode simulation involves the merging of digital and analog simulators in various ways. However, efficient methods for the synchronization between the two time domains remains elusive.
