Class：A Net Class constraint object lets you group net objects that share common characteristics and require a similar constraint requirement
2 \4 A4 [( ~, d5 {; ?Net group：A Net Group is a collection of various net (signal) objects. Different type of net objects, such as nets, buses, differential pairs, and XNets, can be the members of a Net Group.
