Content Description
This module will discuss some advance features of constraints writing
in the User Constraints File (UCF). Topics will include specifying groups
for constraints, ignoring selected paths (TIG), the TPTHRU and TPSYNC
constraints, as will as specifying the time delays for constraints.
Objectives
After completing this training, student will be able to:
- Create groups using either predefined groups or the TNM attribute
- Explain advantages of using the TNM attribute to create groups
- Describe the purpose of the TIG and TPTHRU constraint
