When in Constraint Manager, Physical Domain, one can create a new Physical Constraint Class defining specific attributes for a custom rule set. One can then assing this new rule set to a set of nets. To do that it is instructed to create a new Net Class with menu Objects > Create > Net Class. Also on that same menu is available Net Group. Both options create a group that appear in the Constraint Manager Objects Name Column. I have triied both options and cant really see the difference.
The Question: What is the difference between creating a Net Class and a Net Group ? What are the implications ?
Thanks for your help.
The general differences between a Net Class and Net Group are:
You could create a common Net Group then assign a Constraint Set to drive basic rules:
Implications? Constraint Region Rules and Class to Class Rules cannot be assigned to Net Groups
In addition, Net Classes are domain specific groups so if you wanted to have one larger group of nets to control Spacing rules and a sub-set of those nets to control Physical rules it can be easily done with Net Classes.
Think of Net Groups as a higher level group of objects to organize interfaces.
Hope this helps, Mike Catrambone
You can create a constraint class if you find a tutor on https://studyfy.com/tutoring for your classes. It is always a good option to learn from someone who knows how it works better than you.
Definitely agree with you! And if you need help with your studies and you cannot write your thesis yourself, you can always turn to DissertationTeam and get help from people who really know how to do it. Help is always helpful.
