1. A non-transitory computer-readable medium storing instructions, the instructions comprising: one or more instructions that, when executed by a computer, cause the computer to: import, in a text-based format, a model that describes software or a system in a modeling language into a graphical modeling environment, wherein the modeling language does not define a formal, executable semantic capable of describing a dynamic behavior of the software or system, and wherein the model comprises model components; generate executable elements, in the graphical modeling environment, that represent the model components, wherein at least some of the executable elements comply with standards of a domain or a platform, and wherein the domain or platform comprises CORBA, CORBA-RT, Advanced Architecture Description Language (AADL), AUTOSAR, Software Communication Architecture (SCA) as defined by the Department of Defense, or one or more derivatives of any one of the above; generate an executable model in the graphical modeling environment, the executable model comprising the executable elements and corresponding to the model that describes the software or system; and update: the model that describes the software or system based on changes made to the executable model, or the executable model based on changes made to the model that describes the software or system.
