ANSYS SCADE: Embedded systems and software development
Embedded software is increasingly being used in smart devices, but imperfect code can be the cause of many product failures. Industry leaders estimate that every 1,000 lines of embedded software contain eight bugs. To manage this quality risk, as well as to meet higher standards for software certification, you need to leverage embedded software development tools and certified code generators.
ANSYS provides a model-based embedded software development and simulation environment with a built-in automatic code generator to accelerate embedded software development projects. System and software engineers use ANSYS SCADE solutions to graphically design, verify and automatically generate critical systems and software applications with high dependability requirements. SCADE solutions are highly interoperable and can be easily integrated, allowing for development optimization and increased communication among team members.
Applications
Control mechanisms in control units for drives, brakes, stability programs, driver assistance systems (ADAS), ISO 26262 certified up to ASIL D
Software according to DO-178B & C DAL A e.g. for autopilot, engines, position control, hydraulics.
Software development compatible with EN62304 and FDA 21 CFR part 11
Software for vehicles and infrastructure such as signal boxes or level crossings, EN 50128 SIL 3/4
Control mechanisms for position, temperature, flow etc., IEC 61508 SIL 3/4
Digital image of a smart product in use; additional, virtual sensors for more precise system status; predictive maintenance; condition monitoring; optimum operating status
ANSYS SCADE realizes the model-based development up to the certified machine code and implements a completely integrated process. At the same time, the handling remains intuitive and agile, the hierarchical structure of the software provides a complete overview even with a large number of system states. The generated software is tested simultaneously with the model; time-consuming back-to-back testing and module tests are no longer necessary. Besides the development of controllers and their interaction with sensors and actuators, ANSYS SCADE also covers the development of user interfaces (HMIs). Tools for project management such as requirements management, documentation and traceability ensure product safety.

ANSYS Software supports the model-based development of smart mechatronic products in all disciplines: mechanics, electronics & software. Model-based means that development steps that build on each other are consistent and models are exchanged and constantly refined. This model-based work does not only take place within one discipline, because models can also be used across domains.
In this way, software development can be based on realistic and high-performance behavior models from 3D FEM simulation, while at the same time, mechanics developers can consider the control software as part of the control system when designing an electromechanical component. In both cases, models can optionally be used in a kind of "black box" that does not reveal any internal structure (IP protection) and is easy to operate.
