Verification of Automatically Generated Pattern-Based LTL Specifications

The use of property classifications and patterns, i.e., high-level abstractions that describe common behavior, have been shown to assist practitioners in generating formal specifications that can be used in formal verification techniques. The specification pattern system (SPS) provides descriptions of a collection of patterns. The extent of program execution over which a pattern must hold is described by the notion of scope. SPS provides a manual technique for obtaining formal specifications from a pattern and a scope. The property specification tool (Prospec) extends SPS by introducing composite propositions (CPs), a classification for defining sequential and concurrent behavior to represent pattern and scope parameters, and provides a tool to support users. This work provides general templates for generating formal specifications in linear temporal logic (LTL) for all pattern, scope, and CP combinations. In addition, the work explains the methodology for the verification of the correctness of these templates.
