The problem that this thesis addresses is how to find places in Ada programs where faults are likely to occur during program execution. The approach is to build an automated translation tool that translates Ada programs into a software fault tree. (Lev 83) The tool works as follows: (1) The Ada parser and lexical analyzer calls the Automated Code Translation Tool (ACTT) upon recognition of an Ada statement; (2) The ACTT produces a template representing the statement; (3) The templates are linked together as a software fault tree. The result is a program that takes Ada source code as input and produces a software fault tree as output.
