Telelogic Tau 3.2 -- A Giant Leap Towards Total Integration.

MALMO, Sweden--(BUSINESS WIRE)--Oct. 30, 1997--

Providing seamless design and test of real-time communications systems

Telelogic, the leading supplier of fully functional, integrated tool sets for Unified Modeling Language (UML), Specification Description Language (SDL), Message Sequence Charts (MSC), and Tree and Tabular Combined Notation (TTCN), and their supporting languages and notations, announced today the release of Telelogic Tau 3.2. Telelogic Tau allows communications systems designers to go from object-oriented analysis (OOA) to code generation to system test with a single unified set of tools. This new version of Telelogic Tau provides complete support for executable code generation, remote simulation, state-space exploration, and test-case generation.

"Telelogic has a long list of real-time systems customers who knew it was worth waiting for Telelogic Tau 3.2's unmatched power, openness, and completeness," commented Ingemar Ljungdahl, president of Telelogic AB. "Our new SDL modeling capability dramatically improves productivity by 60 to 80% over C++ modeling tools."

SDT State Charts and High-level MSC Support

Telelogic Tau 3.2's solid formal methods foundation means that simulation and testing can be performed in the development environment. The SDT Analyzer has been significantly improved allowing tasks to run more than ten times faster than with the previous version. A State Chart Editor, part of the Telelogic Tau OOA environment, is now part of the analysis model formed by class/object diagrams and uses cases as a means of expressing high-level behavior. High-level Message Sequence Charts (HMSC), as defined in the MSC-96 release, provides excellent system overview, simplified navigation, and most importantly, a convenient method to define test purposes. The HMSC Editor allows developers to navigate freely between MSC and HMSC diagrams, with the added capability to verify HMSCs in the SDT Validator.

Automatic TTCN Test Suite Generation

A fully automatic TTCN Test Suite Generation, through innovative utilization of the state-space exploration mechanism of the SDT Validator, is now available with this new release, allowing the dynamic as well as the static part of the test to be executed "hands-free".

Additionally, Telelogic Tau 3.2 contains a number of significant changes that will simplify everyday work for SDL designers and testers. For example, Telelogic Tau 3.2 now provides the ability to graphically insert simulator breakpoints into an SDL diagram that may contain non-ASCII character sets.

Split Code for Distributed SDL Systems

Telelogic Tau 3.2 contains advanced support for partitioning automatically generated C code, including a split into several linkable modules. A full SDL system may be implemented by a collection of executable files, not only useful for distributed applications, but also for heavy-weight processes that might otherwise prove too much for that particular execution environment.

ITEX Target Support

The Interactive TTCN Editor and Executor (ITEX), is Telelogic's computer based tool for writing test suites in the TTCN and ASN.1 standard. The ITEX Base, ITEX Cadvanced, and ITEX Access, conform to the Windows(R) look and feel. ITEX Target Support, in the form of a run-time TTCN user interface, is available for ITEX Cadvanced users, supporting a number of functions including test campaign specification, test case start-up, monitoring and tracing, and logging.

CORBA Support

Telelogic Tau 3.2 also supports CORBA, an inter-application communications standard that was introduced in 1991 by the Object Management Group (OMG) (Framingham, Massachusetts). OMG is a non-profit industry consortium dedicated to promoting the theory and practice of object technology for the development of distributed computing systems. Nearly 700 companies participate in OMG today, making OMG the world's largest software development consortium, and establishing CORBA a de facto open standard, controlled by industry.

Telelogic Tau 3.2 support for CORBA include clients as well as servers. The new version improves threads handling and enhances performance, and provides developers with better integration between the real-time operating system (RTOS) and the Object Request Broker (ORB). The ORB is the middleware that establishes the client-server relationships between objects. An ORB allows a client to transparently invoke a method on a server object on the same machine or across a network.

Availability

Telelogic Tao 3.2 is available now for Windows 95, Windows NT, and UNIX workstations.
