背景

https://doi.org/10.1007/978-981-13-6408-2The term ‘formal methods’ has been much used and much abused. It covers a number of methodologies and techniques from the mathematical statement of requirements through formalized design methodologies (Chapter 9) to the automated validation of code (Chapter 11). Thus, formal methods can be applied throughout the life cycle.

Congenital Disorders of the LarynxSoftware design is the process which translates the requirements specification into a detailed representation of a software system. Good software design is essential for reliable and understandable software. Many techniques, with associated tools, have been developed to support software design. Some of the major ones will be described here.

Congenital Disorders of the LarynxIn section 10.1.3 it was explained that static analysis was one particular technique for the review and analysis of source code. Indeed some of the tools available are powerful and enable the technique to be integrated into the design process. A practical example is given in this chapter.
