Unreferenced date December 2009 A specificationlanguage is a formal language used in computer science . Unlike most programming language s, which are directly executable formal languages used to implement a system, specification languages are used during systems analysis , requirements analysis and systems design . Specification languages are generally not directly executed. They describe the system at a much higher level than a programming language. Indeed, it is considered as an error if a requirement specification is cluttered with unnecessary implementation detail, because the specification is meant to describe the what , not the how . A common fundamental assumption of many specification approaches is that programs are modelled as algebra ic or model theory model theoretic structures that include a collection of set mathematics sets of data values together with function mathematics functions over those sets. This level of abstraction is commensurate with the view that the correctness ... oriented approach to specification taken e.g. by Common Algebraic SpecificationLanguage ... in a programming language, or in an executable subset of the specificationlanguage at hand.

The Common Algebraic SpecificationLanguage CASL is a general purpose specificationlanguage based on first order logic with Mathematical induction induction . Partial function s and subtype subsorting are also supported. CASL has been designed by CoFI, the Common Framework Initiative , with the aim to Subsumption architecture subsume many existing specification languages. CASL comprises four levels basic specifications, for the specification of single software modules, structured specifications, for the modular specification of modules, architectural specifications, for the prescription of the structure of implementation s, specification libraries, for storing specifications distributed over the Internet . The four levels are orthogonal to each other. In particular, it is possible to use CASL structured and Software architecture architectural algebraic specification specifications and libraries with logics other than CASL. For this purpose, the logic has to be formalized as an Institution computer science institution . This feature is also used by the CASL extensions.

Unreferenced date July 2009 The Hierarchical Music SpecificationLanguage HMSL is a music programming language written in the 1980s by Larry Polansky , Phil Burk , and David Rosenboom at Mills College . Written on top of Forth programming language Forth , it allowed for the creation of real time interactive music performance systems, algorithmic composition software, and any other kind of program that requires a high degree of musical Music informatics informatics . It was distributed by Frog Peak Music, and runs with a very light memory footprint 1 megabyte on Apple Macintosh Macintosh and Amiga systems. Unlike CSound and other languages for audio sound synthesis synthesis , HMSL is primarily a language for making music . As such, it interfaces with sound making devices through built in MIDI classes. However, it has a high degree of built in understanding of music performance performance practice , musical tuning tuning systems , and Sheet music score reading. Its main interface for the manipulate of musical parameter s is through the metaphor of shape s, which can be created, altered, and combined to create a musical Texture music texture , either by themselves or in response to real time or Scheduling computing scheduled events in a score. HMSL has been widely used by composers working in algorithmic composition for over twenty years. In addition to the authors who are also composers , HMSL has been used in pieces by Nick Didkovsky , The Hub band The Hub , James Tenney , Tom Erbe , and Pauline Oliveros . A Java platform Java port of HMSL was developed by Nick Didkovsky under the name JMSL , and is designed to interface to the JSyn API.

Specifications are written as C annotation comments to the C program, which hence can be compiled with any C compiler. The current verification tool for ACSL is Frama C . Overview ACSL is a Behavioral Interface SpecificationLanguage BISL . It aims at specifying behavioral properties of C source code. The main inspiration for this language comes from the specificationlanguage of the Caduceus tool for deductive verification of behavioral properties of C program s. The specificationlanguage of Caduceus is itself inspired from JML which aims at similar goals for Java source code. One difference with JML , is that ACSL aims at static verification and deductive verification whereas JML aims both at runtime assertion checking and static verification using for instance the ESC Java tool. Syntax Let us consider the following example for the prototype of a function named code incrstar code requires valid p assigns p ensures p old p 1 void incrstar int p The contract is given by the comment which starts with code code .

In computer science , a formal specification is a mathematics mathematical description of software or computer hardware hardware that may be used to develop an implementation . It describes what the system should do, not necessarily how the system should do it. Given such a specification , it is possible to use formal verification techniques to demonstrate that a candidate system design is correct with respect to the specification.
