The OMNeT⁠+⁠+ IDE defines the Simulation Perspective so that it is specifically geared towards the design of simulations. The Simulation Perspective is simply a set of conveniently selected views, arranged to make the creation of NED, INI and MSG files easier. If you are working with INI and NED files a lot, we recommend selecting this perspective. Other perspectives are optimized for different tasks like C⁠+⁠+ development or debugging.
