A specification language is a formal language in computer science used during systems analysis, requirements analysis, and systems design to describe a system at a much higher level than a programming language, which is used to produce the executable code for a system.
The Z notation is an example of a leading formal specification language. Others include the Specification Language (VDM-SL) of the Vienna Development Method and the Abstract Machine Notation (AMN) of the B-Method. In the Web services area, formal specification is often used to describe non-functional properties [7] (Web services quality of ...

An example of a formal specification (in Spanish) using the Z notation, with named schema boxes, including declarations and predicates. The Z notation / ˈ z ɛ d / is a formal specification language used for describing and modelling computing systems. [1] It is targeted at the clear specification of computer programs and computer-based systems ...
The design of a computing system can be expressed using a specification language, which is a formal language that includes a proof system. Using this proof system, formal verification tools can reason about the specification and establish that a system adheres to the specification. [10]
The Larch family of formal specification languages are intended for the precise specification of computing systems. They allow the clean specification of computer programs and the formulation of proofs about program behavior.
However, TLA + specifications are written in a formal language of logic and mathematics, and the precision of specifications written in this language is intended to uncover design flaws before system implementation is underway. [6] Since TLA + specifications are written in a formal language, they are amenable to finite model checking.
A programming language specification can take several forms, including the following: An explicit definition of the syntax and semantics of the language. While syntax is commonly specified using a formal grammar, semantic definitions may be written in natural language (e.g., the approach taken for the C language), or a formal semantics (e.g., the Standard ML [3] and Scheme [4] specifications).
