<p>This work on symbolic time expression is twofold: firstly, it concerns the concepts of TADL2 to manage in a same design, time bases of multiple types (universal time - i.e. chronometric time, angular time, etc.). The second aspect concerns with the extension of constant time expressions and the possibility to define time as an algebraic expression that is able to manipulate symbolic identifiers. So, a value expression in a TADL2 time constraint may refer to an expression made of a suitable set of arithmetic operators mixing symbolic identifiers and referring to different time bases.<br/></p><p><br/></p><p>A typical use for this feature is to capture unknown configuration parameters; another one is to relate constraints in different time-bases to each other.<br/></p>
