Problems solved by technology

FM uses a very difficult branch of mathematics, which may have contributed to the reluctance to use it, thereby failing to gain wider acceptance
In particular, providing proof is a laborious, time-consuming and extremely skillful process
Furthermore, FM is unwieldy even for small applications and is hampered by a lack of practitioners, which in turn makes it expensive to implement
[0006] A consequence of the above is the apparent reluctance of vendors to leverage software to implement safety-critical processes

Embodiment Construction

[0032] can be as figure 1 The software within the AAA shown in is seen as three separate parts. They include: a real-time operating system layer (1) shown by a dotted line, an application layer software (2) shown by a dotted line, and AAA control software (3). The operating system layer (1) includes an operating system (la). The application layer software (2) includes a large number of functional applications ((4). The operating system layer (1) and the application layer software (2) are linked together through the AAA control software (3), and the AAA control software ((3) includes the The application management code (5) associated with the application layer software (2) and the general system management software (6) associated with the operating system layer (1). These three parts are all composed of the backplane support layer (7) and the processor ( 8) Support.

[0033] In order to certify AAA software, each of the three sections must be certified. The key to AAA is pla...

Abstract

Development of validated software codes is a troublesome but important process, in particular for the condition that takes security key application programs into consideration. The invention provides a method for generating validated software codes according to demand, which comprises the following steps: (1) using software to generate the demanded state model; (2) using the state model to develop the software code description of the state model and the mathematic description of the state model; and (3) comparing the software codes with the mathematic description so as to validate that the software code description is correct expression of the mathematic description.

Description

technical field [0001] The present invention relates to methods and implementations thereof in software-based code development, which may be used, for example, in the control of systems such as avionics. Background technique [0002] Over the years, as the reliance on software has grown to provide more complex control operations, software-based implementations of control functions in hardware have become increasingly complex. This has resulted in the development of very large amounts of software code for For complex control operations. [0003] One such example is the development of software code for implementation within the avionics systems of modern fighter jets such as the Euro fighter. The performance characteristics of such aircraft are that they operate in aerodynamically unstable conditions. This requires the help of a large amount of extremely complex computer software. The development and certification of such software can be a very time-consuming process. In th...
