Auto-Create Design States

 
Feature Description
 
The Auto-Create Design States operation can be used to automatically create design states for all valid state combinations on a specified set of objects.
 
Warning: Although it can be a powerful way of solving certain difficult modeling and analysis problems. The automatic generation of design states should be approached with extreme caution. The Analyst should have a good understanding of this section and the Controls provided in eXpress for controlling generation of design states.
 
How to:
 
When the Analyst invokes the Design States "Auto-Create" operation, as shown to the left, more than 2000 design states could be created. This dialog allows the Analyst to confirm whether or not it is desirable for the specified number of design states to be created.
 
The design state Auto-Create dialog uses a tabbed dialog, with separate tabs for
  • Method
  • Details
  • States
  • Signals
These tab window helps can be accessed by the links shown below.
 
 
Design State Option Windows Controls
The Method tab allows the Analyst to specify the method and cutoffs to be used as design states are created.
The Details panel allows the Analyst to control the assignment of names and descriptions to newly-created states.
The States panel allows the Analyst to specify which states can be included for each object (including default state
The Signals panel allows design state auto- creation to be constrained to only states that are related to specified I/O flags.
 
 
For designs with many objects containing states, numerous states per object, and/or non-mutually-exclusive states, the Auto-Create Design States operation can generate an extremely large number of design states.
 
Numerous hierarchically-inherited design states can result in a substantial increase in processing time within the eXpress software—during diagnostic analysis, in particular (for more details on potential problems and how to avoid them, refer to the topics "The Dangers of Using Design States" and "Good Design State Practices").
