<b>The T-VEC Tabular Modeler (TTM) 4.5.0 is now generally available.</b>
<b>The T-VEC Tabular Modeler (TTM) 4.5.0 is now generally available.</b>
Primary Modeling Features/Enhancements:
<ul><li>Added support for 1-Dimensional Array variables</li>
<li>Improved character type and string type support</li>
<li>Improved model include mechanism to allow for selecting multiple include models</li>
<li>Added the concept of Local table variables for specifying and utilizing persistent state information.</li>
<li>Improved expression formatting (allows formatting of expressions even when there are model check errors)</li>
<li>Improved navigation from error/warning messages to actual error location and model elements</li>
<li>Improved interface for conditional table cells (vertical scrollbar, multiple row delete)</li>
<li>Now supports the specification of an alternate (i.e. non-default) report directory</li>
<li>Auto-fix identifiers function now works for local elements (function parameters, modes, structure fields)</li>
<li>Enhanced the Assignment column auto-fill feature to fill a new column with appropriate structure and local elements and values when possible</li>
<li>Enhanced find function
    <ul><li>More search locations (all available navigable location)</li>
<li>Search results from Mode Machine transition tables and requirement descriptions are now available.</li>
<li>Improved search filter allows searching for local elements independently from the parent</li></ul></li>
<li>Initial set of TTM library functions can now be found in <INSTALL_DIR>\translators\ttm\lib</li>
<li>Default/demo TTM test driver schema file and perl routine file can now be found in <INSTALL_DIR>\translators\ttm\test_drivers. This schema is targeted to code produced by Simulink's rtw code generator. Although they require some user configuration, they should help point the way to producing test drivers from TTM requirement models targeted to code generated from Simulink design models.</li>
<li>Added default map file variables to .map files that are referenced in the demo TTM test driver schema file.</li>
TTM Model Checker:
<ul><li>Improved floating point value checking
<ul><li>Points out floating point constants with too many significant digits</li>
<li>Points out the use of degenerate forms of floating point constants. Values such as ".1" or "1." are now required to be in the more canonical form "1.0" or "0.1".</li></ul>
<li>Improved checking for duplicated and/or bad identifiers</li>
<li>Improved assignment expression syntax checking and formatting</li>
<li>Added support for binary operator XOR ('^') and NOT ('~')</li>
TTM/DOORS Integration:
<ul><li>Enhanced the model manager to work better with DOORS integration</li>
<li>Enhanced navigation from DOORS to TTM, the navigation will always bring up a TTM GUI with the correct model if one exists.</li>
<li>Improved user-friendliness of the DOORS integration dialog
<ul><li>Now is resizable to allow viewing of long module names</li>
<li>Now allows multiple selection of doors module to add, synchronize, and delete (4.3.0 -10/08)</li>
<li>Now allows synchronization through the context menu of a DOORS item (4.3.0 -10/08)</li>
