ISO 16781:2013 provides guidance to control system engineers on what to simulate and how to use simulation to support their system engineering tasks. ISO 16781:2013 provides simulation requirements of control system for different phases in the process of designing a control system. Control system engineers can carry out various types of simulation experiments during various phases, according to ISO 16781:2013. ISO 16781:2013 establishes a minimum set of requirements for simulation of control system. The requirements are generic in nature because of their broad applicability to all types of simulations.
