Embodiment approach

[0094] In step 41, the reverse execution of the function that allows the detected defective instruction string to be traced back to the program is started. In one embodiment of the present invention, the reverse execution is completed between two consecutive marks (interval). In the most common case this corresponds to the start and end of the defect function. It is of course possible to jump from one interval to another without any special restrictions. In another specific embodiment, the reverse execution is carried out over a narrow range around the error, in other words only over a part of the function.

[0095] In step 42 , the developer performs error debugging, in other words he detects errors in defective function sections and corrects them. When the debugging step 42 ends, the method repeats step 31 in order to check whether the program was executed correctly.

[0096] When the control unit no longer detects interrupts on processor exceptions, the control unit then...

Abstract

The invention relates to a method for debugging a program of running software of an airborne system, which is characterized in that it comprises the following steps: a) setting up marks (31) for the program by arranging marks along the execution path, so as to divide the execution path into Adjacent function intervals; b) execute (32) the program normally; c) capture (33) the program execution state through the flag state vector; d) when an error is detected: search (36) the defective one according to the flag state vector A function interval, reverse execution (41) of the program in the defective function interval; determining and correcting (42) the error.

Description

technical field [0001] The present invention is in the field of safety of the operation of systems when their operation depends on the execution of sequences of logical instructions in a computer. [0002] In particular, the invention aims at a method for debugging the operating software of a system that is supposed to execute a sequence of logical instructions, especially a system with high safety requirements, such as an electronic system specially mounted on an aircraft. [0003] The method enables developers to search for and correct errors in the logical sequence of instructions for operating software on an airborne system. The invention has particular advantages, not exclusively, in the field of aeronautics and especially in the field of test execution of software dedicated to the operation of airborne systems. Background technique [0004] For safety reasons, systems intended to be installed on aircraft need to be checked for good operation. During the checks, the sy...
