CATIA Systems Architecture

From aircraft to cars, industrial machinery, ships, and white goods, complexity of products and the systems that keep them running is steadily increasing. CATIA enables you to model and compose complex products, while defining and executing their driving systems to manage this complexity and deliver products on time?

CATIA Automated Process Creation

The HILS interface allows systems engineers to export models developed in CATIA DBM in order to use them to perform ‘Hardware in the Loop’ (HIL) simulations

Today’s complex electro-mechanical products have their behavior largely driven by embedded controllers. The ‘whole system’ behavior of these products, including both the controlled parts and the controllers themselves, can be modeled in CATIA Systems Dynamic Behavior Modeling (DBM). The Systems DBM export for HILS product can then be used to export the controlled model (i.e. the plant model) for use in a validation environment. In this context, the plant model is used as an input/output simulator used for simulating and tuning the actual physical controller under real-time conditions.

Optimized real-time computers benefit from both speed and size features allowing them to be located and loaded near to the controller. These real-time computers can then be used to validate the controller design in realistic conditions, avoiding costs and risks associated with simulations that would use the real physical plant. Using this export option, the C code generated from the systems plant model can be processed for use in HIL simulations on platforms such as dSPACE and xPC targets.

  • Shorten the development time for complex systems by virtually running plant models to validate new Electronic Control Units (ECU’s)
  • Benefit from high-performance simulation implementations
  • Avoid costs and risks associated with simulations based on the real physical plant
  • Generation of C code supporting real time capabilities
    An embedded fixed step integrator ensures that the generated C code can run on DSpace and xPC targets, thanks to The MathWorks Real Time Workshop (RTW) code generator.
  • Take advantage of special techniques for HIL simulation
    such as inline integration.
  • Latest xPC and dSPACE target environments supported
    o Systems DBM export for HILS ensures a Real-time simulation on xPC Target version 3.0 (or later) and/or dSPACE Release 5.0 (or later).
