The T-VEC Vector Generation System (VGS) is the engine to supports:

  • Model analysis
  • Test vector generation
  • Test driver
  • Test results analysis
  • Project status and measurement


The VGS was first used in the FAA certification of the Traffic and Collision Avoidance (TCAS) system in 1990. T-VEC was applied to the entire MD90 (McDonnell Douglas) Electrical Power System Variable Speed Constant Frequency (VSCF) system that was FAA-certified in January of 1995.

In 1998 VGS was integrated with the original SCR tool. Since that time it has continued to evolve and support other integrations with various modeling tools such as MATRIXx and more recently Simulink/Stateflow.



VGS has a wide array of test vector generation options, but the default vector generation functions are accessible to user through a single menu option called Build that performs the build process based on the dependencies, much like make. This function is also provide through a command or console function to permit batch-oriented test generation.
