BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-89-1267 ENTRY:: September 27, 1994 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: A really temporal logic. TYPE:: Technical Report AUTHOR:: Alur, Rajeev AUTHOR:: Henzinger, Thomas A. DATE:: July 1989 PAGES:: 29 ABSTRACT:: We introduce a real-time temporal logic for the specification of reactive systems. The novel feature of our logic, TPTL, is the adoption of temporal operators as quantifiers over time variables; every modality binds a variable to the time(s) it refers to. TPTL is demonstrated to be both a natural specification language as well as a suitable formalism for verification and synthesis. We present a tableau-based decision procedure and model-checking algorithm for TPTL. Several generalizations of TPTL are shown to be highly undecidable.
