<p>The invention includes a method and apparatus for managing a system specification. The method includes identifying a first system specification defined at a first refinement level where the first system specification includes specification data, generating a second system specification at a second refinement level where the second system specification inherits the specification data of the first system specification, modifying the inherited specification data of the second system specification, and storing the second system specification including the modified specification data.</p> |
