Siemens helps Arm prepare for Software-defined vehicles (SDV) with Arm Cortex-A720 AE pre-silicon support

sw.siemens.com/, Mar. 13, 2024 – 

Developers of SDVs are facing unparalleled software complexity. Software for SDVs could take up 100M lines of code rising to 300M+ lines in the near future causing untold difficulties in integration, testing and validation, and organizational strategy.

In SDVs, innovation and value will come from software and hardware optimized to run that software, not just from the conventional Electronic Control Unit (ECU) hardware. So software is an issue that won't just go away.

Exploring the challenges of the SDV

Consumers want the same highly sophisticated software features in their cars that they are familiar with from their consumer electronics devices. Integration of these new software features is the first challenge facing developers. This is further compounded by a distributed development environment with OEMs relying on an increasing number of supply chain partners to fulfil consumers' demand and retain competitiveness.

Testing and validating functionality of ever-increasing volume of software is the second challenge facing developers of SDVs. Everything needs to be unit tested, integration tested, and regression tested to achieve the highest quality. Unfortunately, the supporting tools available to SDV developers fall woefully short of enabling the level of validation needed.
