An identifier that refers to all versions of a specific simulator, such as “FRED”. We intend that it uniquely identify a simulator when combined with simulator developer.

The implementation of namespace control for simulator name (i.e., making sure that they don’t use “FRED” twice) is the responsibility of simulator developer. complete simulator identifier software identifier identifier
