SIMULTAAN Simulator Architecture (SSA)

• Traditionally, a federate has functional parts
• Now SSA identifies Simulator Components
• Components are functional units
• Components have formal interfaces (OMTs)
• Federate is set of interacting components
• SSA extends HLA with the Component Level

SSA Simulation Architecture

• SSA key elements
• Components
• Run-time Communication Infrastructure (RCI)
• Federate Manager (a special Component)
• Federation Manager (a special Federate)
• in addition to
• SSA Rules
• SSA Interface Specification
• SSA Object Model Templates (OMTs)

SSA Standard Elements Run-time Communication
Infrastructure (RCI)

• Implements the JSA Interface Specification
• RCI is a software framework providing an
  interoperability middle-ware layer
• Code Generation, based on OMTs, provides the
  softwareskeleton for interfacing the functional
  part of the Component and the RCI

RCI Automatic Code Generation

• Interface code generation (C) from COM (or SOM)
• Minimize programming and debugging time
• Highly successful approach in SIMULTAAN, ITEC
  demos and JSA !

SSA Standard Elements Federate Manager

• Represents the Federate to the Federation
• Creates and Joins the Federate
• Exchanges data between the Components and the
  rest of the Federation (gateway)
• Co-ordinates the State of all Components
