Question

NOTE:

1) the vpiWith relation is only available for randomize methods (see Section 12.6) and for array locator methods (see Section 4.15.1).

2) For methods (method func call, method task call), the vpiPrefix relation will return the object to which the method is being applied. For example, for the class method invocation

packet.send();

the prefix for the "send" method is the class var "packet"
