就是把所有data feature都開啟包括copy, compare, print等If FLAG is set to UVM_ALL_ON, as in the example, the ARG variable will be included in all data methods. The FLAG, if set to something other than UVM_ALL_ON orUVM_DEFAULT, specifies which data method implementations will NOT include the given variable. Thus, if FLAG is specified as NO_COMPARE, the ARG variable will not affect comparison operations, but it will be included in everything else.All possible values for FLAG are listed and described below. Multiple flag values can be bitwise ORed together (in most cases they may be added together as well, but care must be taken when using the + operator to ensure that the same bit is not added more than once).UVM_ALL_ON Set all operations on (default).UVM_DEFAULT Use the default flag settings.UVM_NOCOPY Do not copy this field.UVM_NOCOMPARE Do not compare this field.UVM_NOPRINT Do not print this field.UVM_NODEFPRINT Do not print the field if it is the same as itsUVM_NOPACK Do not pack or unpack this field.UVM_PHYSICAL Treat as a physical field. Use physical setting in policyclass for this field.UVM_ABSTRACT Treat as an abstract field. Use the abstract setting in thepolicy class for this field.UVM_READONLY Do not allow setting of this field from the set_*_localmethods.
