Upcoming changes

T-VEC is constantly improving our tools. Upcoming changes:
TTM
  • Global Variables to support global state
  • Support for control/closed loop feedback related requirement
  • Constant structures and arrays
  • Model includes referencing parametrized models
  • Temporal Operators in TTM
VGS
  • Floating point precision control option in VGS
  • Visual display of dcp path in Matlab.
  • Test Driver Access to TTM Comments/Requirement Text
  • State variable and associated initialization mechanisms
  • Variation for array expression that is more concise for values applied to entire arrays

Getting Started

The multi-media video provides a quick way to get a Tool Suite Overview.

The T-VEC suite of tools provide model-based test support. The tools include:

  • T-VEC Vector Generation System (VGS)
    • VGS is the engine that provides model analysis, test vector generation, test driver generation, test results analysis, project status, and measurement reporting

If you're new to modeling, TTM is easy to use, and you can create your first model in a matter of minutes. TTM integrates seamlessly with VGS, and with one mouse click tests for your first model can be produced quickly. TTM has built-in help, tutorials, and course exercises built-in to the installation.

Simulink users can use SL2TVEC and VGS to support model analysis, test generation, and execution for auto-generated code, manually produced code, and the Matlab simulator.

VGS is the core T-VEC technologies developed in the late 1980's and early 1990's. It is a rather mature technology, and has not changed in any real fundamental way since the documentation. Most of the default setting provide the optimal set of tests.

Pilot Projects or Workshops are often the best way to get started with T-VEC tools.
