Innovators at NASA's Johnson Space Center have developed a framework that removes the complexity of adhering to the Institute of Electrical and Electronics Engineers (IEEE®) 1516-2000 High Level Architecture (HLA) standards for simulation interoperability. With the Trick High Level Architecture (TrickHLA) interoperability framework, computer simulations can communicate with other computer simulations regardless of the computing platforms and without the developer having to be proficient with the IEEE HLA standard. TrickHLA abstracts the complexities of using the IEEE 1516-2000 HLA specification for simulation integration. The framework is data driven and includes a simple application programming interface (API), making it relatively easy to enhance an existing Trick simulation into a distributed simulation. This software may be released for U.S. Government purposes only.

  • Straightforward: Includes a simple API
  • Multi-phased: Allows for the individual simulations that make up a distributed simulation to initialize in phases which resolves the interdependencies between simulations during initiation
  • Data driven: Permits the IEEE 1516-2000 HLA simulation configuration to be changed without recompiling
  • Automated: Removes the need for writing complex software to handle the transport of data between simulations


  • Integrating existing simulations developed with the Trick Simulation Environment with other simulation programs via the IEEE 1516-2000 HLA specification
