Jtlv: A Framework for Developing Verification Algorithms. Jtlv is a computer-aided verification scripting environment offering state-of-the-art Integrated Developer Environment for algorithmic verification applications. Jtlv may be viewed as a new, and much enhanced Tlv [18], with Java rather than Tlv-basic as the scripting language. JTLV attaches its internal parsers as an Eclipse editor, and facilitates a rich, common, and abstract verification developer environment that is implemented as an Eclipse plugin.
