Related snippets (backlinks) Figure 16-5 illustrates the use of the Copy dependency to allow a single requirement to be reused in several requirements hierarchies. The master tag provides a textual reference to the reused requirement. Since the concept of requirements reuse is very important in many applications, SysML introduces the concept of a slave requirement. A slave requirement is a requirement whose text property is a read-only copy of the text property of a master requirement. The text property of the slave requirement is constrained to be the same as the text property of the related master requirement. The master/slave relationship is indicated by the use of the copy relationship. AbstractRequirement::/master : AbstractRequirement [0..*] This is a derived property that lists the master requirement for this slave requirement. The master attribute is derived from the supplier of the Copy dependency ... Visit also Visit also (backlinks) Flags
