Verification system and method for body control module software

A verification method for BCM software, comprising the steps of:

• creating a plurality of input signals into an Excel file using an orthogonal array;
• inputting orthogonal array data of the Excel file created in the above creating step into an input unit of a verification program;
• allocating Excel file data to an input port of the BCM;
• converting the Excel file into a header file that can be compiled by a microcomputer of the BCM and compiling the header file together with software of the BCM;
• applying power to the BCM using an on/off control of a power supply unit and allowing input conditions to be inputted to the BCM by means of the inserted header file;
• allowing a relevant output signal to be generated by the BCM and storing the relevant output signal in an output unit;
• allowing the output unit to automatically output a test result and comparing the output result with a predetermined result to determine whether the BCM is acceptable or not;
• extracting a cause factor of problem occurrence through an analysis scheme;
• and
• finding an error of the software of the BCM using the cause factor of the problem occurrence.
