Ashish Sethi, the Technical Program Director of PAVE360 at Siemens EDA, showcased a range of innovations at Embedded World, including an accelerated development environment for the newly announced Arm Cortex-A720AE processor. Traditionally, waiting for silicon availability has delayed software development, but with the shift towards Software-Defined Vehicle (SDV) and software-led design, the need to start software development early has become crucial. Sethi emphasized the importance of simulating the CPU early in the development process, which is achieved through optimizing cloud configurations and resources to run A720AE models at super-fast simulation speeds, almost equivalent to real-time operation.
The PAVE360 environment aims to expedite software development, design, and hardware validation for OEMs and Tier-1 suppliers. By providing a platform that closely mimics real hardware, developers can begin software development long before silicon availability-a strategy known as "shift left." Collaborating closely with Arm, Siemens EDA endeavors to provide fast simulation environments to enable software partners to familiarize themselves with the latest technologies, such as the A720AE CPU, swiftly and efficiently.
The Arm Cortex-A720AE is tailored for the automotive market, boasting high-performance capabilities with multiple configurable cores. Sethi highlighted the flexibility of the CPU, which can be configured with varying numbers of cores to suit different applications. The demonstration showcased a configuration with 14 cores, all simulated in the cloud using a hyper-accelerated model within Siemens EDA's pre-silicon development environment.
Regarding the hardware used in the cloud, specifics were not disclosed, as the focus lies on optimizing resources for performance and cost efficiency. The collaboration between Siemens EDA, Arm, and AWS aims to provide unprecedented simulation speeds, enabling software partners to port their applications onto the latest A720AE CPU quickly. The environment has garnered interest from various software partners, with some achieving software porting within a matter of weeks.
The Cortex-A720AE's primary focus on automotive applications aligns with the growing demand for high-performance computing in autonomous driving systems. The CPU is designed to handle multiple Electronic Control Unit (ECU) functions within vehicles, including Infotainment and Advanced Driver Assistance Systems (ADAS), while also supporting Level 4 autonomous driving capabilities.
In addition to software development, the platform supports the integration of real-world stimulus into virtual systems. This capability allows for the testing of autonomous vehicle algorithms within a simulated environment, synchronized with external hardware to mimic real-world conditions accurately. The expectation is that such mechanisms will become essential for next-generation software-defined vehicles, given the complexity of integrating and testing large amounts of software.
The partnership between Siemens EDA and Arm reflects a shared belief in the importance of Arm's architecture in the automotive sector. As autonomous driving becomes more prevalent, there may be industry-wide standards and requirements for vehicle performance and capabilities. The A720AE CPU could potentially set a benchmark for such requirements, driving further adoption of Arm's technology in the automotive industry. While the ultimate impact on government regulations remains uncertain, the A720AE platform is positioned to be a leading solution for next-generation vehicle development.
