The present invention relates to a system and methodology to facilitate timely delivery of notifications and performance of automated actions for users in the framework of an ad-hoc rules processing environment. One technique includes editing the drawing to define a current path having a current subpath, matching a previous vertex in a previous path with a current vertex in the current path, and assigning a current subpath attribute to the current subpath based on the vertex match. A first step involves obtaining a coverage group from the DUT design, for examining during the design test verification process. The pseudo-virus induces stronger immune response than DNA vaccines.
