An object-oriented requirements specifications method

Abstract

Analyzing requirements fey object-oriented software is examined in an alternative methodology from the more standard structured analysis approach. Through parallel processes of decomposing objects and allocating functions, the methodology is explained in detail.

Generation of Executable Testbenches from Natural Language Requirement Specifications for Embedded Real-Time Systems

“…In general, there has been early work for the formalization of text by entity relationship diagrams like [1] and multiple work for the generation of test cases from test scenarios like [13]. However, we are not aware of any work which combines those for the generation of complete test environments (i.e., testbench architectures and test cases) for real-time systems taking advantage of principles of functional verification, e.g., functional coverage and constraint based test pattern generation.…”

“…When applying a simple tool like MS Excel, we can easily sort the final sentences by the first identifier (i.e., the subject), which helps to easily check for duplicates or subjects with similar meaning and even for incomplete specifications which can hardly be detected in the unstructured original text. The final TNF is nothing else than the textual representation of Class Diagrams which can thus be automatically derived along early works of Bailin [1]. For this consider the following TNF sentence examples:…”

“…Additionally, we define a method pre_randomize() for the SystemVerilog class, which instantiates array data in preparation for randomization and initializes values that are not randomized like the interpolation function. [1].ipol = ramp; ……”

NL-OOPS: from natural language to object oriented requirements using the natural language processing system LOLITA

“…To limit this problem, Bailin (1989) proposes a different solution, based on ' filtering ' the requirements text to build a requirements database, so as to simplify the search for nouns and noun-phrases. However, no details are given on how to achieve this simplification.…”

A framework for software development for distributed parallel computing systems

“…The nouns in the specification can be candidates for the objects and the verbs as the operations of that object [4]. Another strategy is to draw the dataflow diagrams first and then detect the candidates for objects from this diagram [5]. Other techni ues for identifying the objects are summarized in [47.…”
