Virtual development environment for fast automotive application software development

2 min read

Renesas has launched a virtual development environment that enables advance development and operational evaluation of automotive application software to support the latest requirements of electrical/electronic architecture (E/E architecture).

The new environment includes a Virtual Turnkey Platform, which will allow engineers to develop application software before devices or evaluation boards are available. Additionally, the environment offers a Multicore Debug and Trace Tool, which enables users to analyse and evaluate the operation of their software as if it were running on an actual chip.

These tools will allow customers to kick-start development and get to market faster with leading-edge software.

 “With the evolution of E/E architecture, there is an increasing demand for software design that can maximise performance at a system level. At the same time, the increasing time and cost associated with software development have become a big challenge,” said Hiroshi Kawaguchi, Vice President, Automotive Software Development Division at Renesas. “Our integrated software development environment that can be used across gateway systems, ADAS, and xEV development, enables customers to benefit from the scalability of Renesas products such as R-Car and the RH850 family for both software and hardware development.”

The Virtual Turnkey platform consists of the R-Car Virtual Platform (R-Car VPF) development environment and a software development kit (R-Car SDK) that includes pre-tested software libraries and sample code. The R-Car VPF is based on Virtualizer Development Kits (VDKs) from Synopsys, and integrates virtual models of intellectual property (IP) specific to R-Car to customize for R-Car devices.

By overlaying the R-Car SDK on this platform, engineers will be able to immediately start development of application software virtually. The platform accurately recreates the behaviour of the actual chip eliminating the need to build up a development environment with a physical evaluation board. Multiple users can also develop software simultaneously on separate PCs or servers.

 Once engineers complete the development of multiple software components side by side on the Virtual Turnkey Platform, the next step is to integrate the software and verify that it runs on a single chip. Software components share resources such as the multiple CPUs and IPs on R-Car SoCs.

If operational problems are detected after the software components are integrated, it requires a tremendous amount of work to address these issues, so Renesas has created the Multicore Debug and Trace Tool, which simplifies the process of identifying the causes of errors occurring from the interaction of the multiple hardware resources in R-Car SoCs. This enables synchronous and simultaneous debugging of the entire heterogeneous architecture of R-Car without using the actual device. This helps identify potential problems and thus accelerates the development process.

The development environment is available for the R-Car S4 SoC for automotive gateways. Renesas has plans to support the R-Car V4H as well as future versions of R-Car products and RH850 automotive MCUs.
