The requirements model environment includes a set of parameters and configuration options that define various aspects of the model content and behavior. You can set these parameters:
At model creation
After creating a model with default options and parameters
When creating a model template
Selecting Extended Model Definitions at Model Creation
Extended model definitions (.XEM files) provide means for customizing and extending PowerDesigner metaclasses, parameters and generation. Extended model definitions are typed like models in PowerDesigner. You create an extended model definition for a specific type of model and you cannot share these files between heterogeneous models.
Setting RQM Model Options
This section explains how to set global options for the objects in your RQM. For information about controlling the naming conventions of your model objects other than the requirement object, see "Naming Conventions" section in the Models chapter of the Core Features Guide. To set Model Settings, select Tools Model Options .
Requirements Model Extended Dependencies
Extended dependencies are links between objects of a requirements model. These links help to make object relationships clearer but are not interpreted and checked by PowerDesigner, as they are meant to be used for documentation purposes only.
