Setting Up an SDL and TTCN Integrated Simulation


A complete test of a system design can be performed prior to building a prototype by designing the system in SDL, and using the TTCN Suite to write test specifications in TTCN, or using a tool to automatically or semi-automatically generate test suites from a system description in any language. The actual testing is then a matter of connecting the two simulators.

To achieve the connection, follow these steps:

  1. Generate and start the SDL Simulator.
  2. Start the SDL and TTCN Integrated Simulator by selecting the Integrated-Simulator quick-button from the tool bar of the Browser.
  3. When the SDL and TTCN Integrated Simulator has appeared, along with a selection of executable test cases and test groups, enter the command
    start-itex in the SDL Simulator.
  4. Select one or more test cases or test groups in the SDL and TTCN Integrated Simulator Setup window, and click the Run Test button.
  5. In the SDL Simulator, give any of the start commands (Forever, Go...).

The loaded SDL system is now being simulated on the SDL Suite side, and conformance tested from the TTCN Suite side with the SDL and TTCN Integrated Simulator.
