Renesas updates Model-Based Development Environment

Renesas Electronics Corporation has launched the updated Embedded Target for RH850 Multicore model-based development environment for multicore microcontrollers (MCUs) for automotive control applications. The update supports the development of systems with multirate control (multiple control periods), which is now common in systems such as engine and body control systems. This model-based development environment has become practical even in software development scenarios for multicore MCUs and can reduce the increasingly complex software development burdens especially in control system development of self-driving cars.

The updated version will be available starting in the fall of 2018. Renesas will present a demonstration of this development environment on July 3, 2018, at the MathWorks Automotive Conference 2018 at the Tokyo Conference Center, Shinagawa.

“Model-based development is becoming increasingly common, and Renesas has now completed an environment that covers from control design through automatic code generation. At the same time, since multicore software is complex, it was difficult to handle such software in earlier model-based development environments. Leveraging our extensive expertise in automotive control use cases, we were able to start working on the practical application of this technology early on, and thus succeeded in creating this update,”,” said Hiroyuki Kondo, Vice President of Shared R&D Division 1, Automotive Solution Business Unit, Renesas Electronics Corporation.

Now, to meet the ever-increasing requirements for engine and vehicle performance, and at the same time shorten product development time, by making this development environment support multi-rate control, it is possible to directly generate the multicore software code from the multi-rate control model. This has made it possible to evaluate the execution performance in simulation. Not only does this allow execution performance to be estimated from the earliest stages of software development, this also makes it easy to feedback the verification results into the model itself, the company said.
