Welcome to the T-VEC Wiki
The T-VEC wiki provides information about T-VEC's suite of tools, how to use them, and any other related information. It has no specific topic, but is for all things related to T-VEC. Everyone has access to the wiki, but only registered users can edit content. We encourage users to donate meaningful documentation and information to the T-VEC wiki.

|May-2009: Updates to all the T-VEC tools have been released. Major changes include:
- The Scenario View - This provides customer configuration of test vector generation on a DCP by DCP, or sets of DCPs, basis.
- Added support for 1-Dimensional Array variables.
- Added the concept of Local table variables for specifying and utilizing persistent state information.
- Improved support for a variety of blocks.
- Improved stateflow support.
- Improved C test driver support.
- Improved simulation test driver support.
|October-2008: New coverage option Force Block Output Propagation that extends the ForcePaths/ForceConditions coverage options.
|Feb-2008: Enhancements to TTM/T-VEC Model Checking features of Output and Term Table Disjointedness Checking and Mode Machine Race Condition Checking.
|Feb-2008: Updates in Simulink 2007a provide better integration for automated test driver generation of stateflow See also LDRA Integration for Model References
|May-2008: String functionality in TTM
|T-VEC is constantly improving our tools. Upcoming changes:

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.
Tvecwiki provides guidance on using the tools, from installation, tutorials, usage, and FAQs.
