A discrete-event simulation (DES) models the operation of a system as a sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. [ 1 ] Between consecutive events, no change in the system is assumed to occur; thus the simulation time can directly jump to the occurrence time of the ...
In control engineering, a discrete-event dynamic system (DEDS) is a discrete-state, event-driven system of which the state evolution depends entirely on the occurrence of asynchronous discrete events over time.
A framework for discrete-event simulation in Java, supporting hybrid event/process models and providing animation in 2D and 3D. gem5: C++: Application August 8, 2024 BSD: The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture.

DEVS, abbreviating Discrete Event System Specification, is a modular and hierarchical formalism for modeling and analyzing general systems that can be discrete event systems which might be described by state transition tables, and continuous state systems which might be described by differential equations, and hybrid continuous state and discrete event systems.
FD-DEVS (Finite & Deterministic Discrete Event System Specification) is a formalism for modeling and analyzing discrete event dynamic systems in both simulation and verification ways. FD-DEVS also provides modular and hierarchical modeling features which have been inherited from Classic DEVS.
STELLA - system dynamics and discrete event modeling software for business strategy, public policy, and education. Developed by isee systems. TRNSYS - software for dynamic simulation of renewable energy systems, HVAC systems, building energy use and both passive and active solar systems.
SimEvents is a discrete event simulation tool developed by MathWorks. It adds a library of graphical building blocks for modeling queuing systems to the Simulink environment. It also adds an event-based simulation engine to the time-based simulation engine in Simulink [2]
adevs is a C++ library for building discrete event simulations. Adevs based on the Discrete Event System Specification DEVS and Dynamic DEVS modeling formalisms; it supports parallel discrete event simulation and a runtime system for OpenModelica. Adevs is developed by Jim Nutaro.
