Systems Product Highlights

New capabilities for ANSYS Simplorer enable you to design complete electrical systems with a new graphical modeling editor for Modelica, new Reduced-Order Model interfaces and compatibility with model libraries from Modelon. Its enhanced interoperability capabilities give you improved connectivity with systems engineering processes, support for Functional Mock-up Interface (FMI) co-simulation, system model identification and closed-loop testing with embedded software designs in ANSYS SCADE. Finally, inclusion of Simplorer Entry into ANSYS mechanical, fluids, electromagnetics and embedded software products adds systems simulation capability to ANSYS physics and software solutions.

SCADE Architect Integration with medini analyze

With the release of ANSYS 18.2, ANSYS medini analyze now integrates with SCADE Architect, the ANSYS system and software architecture modeling tool.

The ANSYS SCADE Suite product line has set the standard in the global aerospace and automotive industries for system architecture modeling and automated generation of embedded software code. SCADE's proven, step-by-step method for modeling a robust control system architecture ensures that all critical components that govern braking, steering and other functions work together seamlessly and reliably. Software engineers can work quickly and efficiently to generate mission-critical code, with the assurance that they will meet both regulatory standards and project deadlines.

ANSYS medini analyze automates the modeling and verification of functional safety for electronic control systems in domains like automotive and aerospace. Similar to ANSYS SCADE, medini analyze provides a step-by-step modeling and verification process. The result is a system architecture that accounts for the safe, reliable interactions of dozens of components. In addition, medini analyze automates the analysis of failure modes and the response of the overall system under a wide range of operating scenarios.

By using these two specialized modeling tools together, for the first time engineers in the industry have a seamlessly integrated toolkit. The same reliable, step-by-step process will ensure the creation of system architectures that meet all relevant industry standards for safety and control — quickly and cost-effectively.

Transient failure extension

With the release of ANSYS 18.2, ANSYS medini analyze now supports transient failure analysis. Transient failures (or soft errors) occur at irregular and unpredictable times due to alpha particles or other radiations. They need special treatment in chip design when it comes to safety applications, since their impact on safety-critical software can be mission-critical.

ANSYS medini analyze is the first tool to introduce a transient failure modeling and distinct FMEDA for chip-level safety analysis. Transient failures can be attached to the chip architecture elements, for example at RAM/ROM modules, digital logic, busses, etc., of a chip design. Quantification by means of failure rates is supported per JEDEC standard JESD89A or own sources.

The impact of transient failures can be visualized and combined using failure nets, FME(D)A spreadsheets and FTA. Soft errors at the chip level can be traced back to IP implementation designs loaded into medini analyze from hardware description languages (HDL) for a complete view of the hazardous impact of the chip failures. This allows a consistent analysis from early stages in the development cycle down to implementation in silicon.

With the introduction of transient failure analysis, semiconductor companies and chip integrators can reduce costs and time to market through efficient validation at any stage of the development cycle. Safety engineers can compute enhanced failure metrics to analyze the impact of both permanent and transient failures in a separated and combined way.

New graphical modeling environment helps you to simulate complete physical systems

Modeling complete physical systems is easier than ever with the new, diagram-based graphical modeling environment for the industry-standard Modelica language. Simplorer now covers fluid power, liquid cooling and mechanical dynamics. A new Reduced-Order Model (ROM) generator for coupled mechanical–thermal behavior also lets you analyze and reuse 3-D physics-based models at the systems level.

Enhanced interoperability improves complex systems integration

With new support for FMI co-simulation, system model identification, connections to systems engineering flows and support for closed-loop testing with embedded software, Simplorer increases its lead over the competition in terms of interoperability of varied simulation technologies. The new systems engineering gateway connects physical system simulation in Simplorer with system architecture design in ANSYS SCADE Architect, and embedded software models created with ANSYS SCADE Suite can be validated with a new closed-loop system testing methodology.

Simplorer Entry adds systems simulation to ANSYS physics and embedded solvers

ANSYS Simplorer Entry extends multiphysics analysis and optimization to the system level. You can now include systems analysis in any design involving ANSYS mechanical, fluids, electromagnetics and embedded software solutions. Simplorer Entry gives you access to all the languages, model libraries, solvers and interfaces available in the full Simplorer product, and is only limited in the size of model that it can simulate. For ANSYS SCADE users, Simplorer Entry is a powerful platform for modeling physical plant behavior and testing embedded controls within the system.

FMEDA Capabilities in ANSYS medini for Semiconductors

FMEDA Capabilities in ANSYS medini for SemiconductorsChips are becoming extremely complex systems, with a deep impact on the safety and security of the products that contain them, such as automobiles. The revision of the ISO 26262 2nd edition international standard dedicated to product development processes for safety-related electrical and/or electronic (E/E) systems poses new challenges for semiconductors. The standard mandates that automotive semiconductor suppliers perform system safety analysis for all chips to be included in cars and other on-road or off-road vehicles.

Our latest release, ANSYS 18.1, can ensure that your automotive semiconductors comply with this new standard. ANSYS medini includes Failure Mode and Effect Analysis for Design Automation (FMEDA) for systems safety analysis, which is applicable for a full system-on-chip, a complex IP or a basic hardware function. ANSYS 18.1 also integrates bilateral communication with the Cadence IP design tool.

ANSYS medini for semiconductors includes:

  • Failure rate determination for hardware design (chip + package)
  • FMEDA analysis based on the hardware design models
  • Seamless Import of IP design data
  • The ability to configure, exchange and reuse FMEDA data
  • All all other medini analyze features, including safety requirements and traceability, fault tree analysis, dependent failure analysis and checklists, etc.
