A Comprehensive Approach to Power & Performance Optimization

Revolutionizing Systems Engineering with VisualSim

As the automotive industry transitions into an era dominated by digital and electronic solutions, the design challenges associated with Electronic/Electrical (E/E) architectures have become increasingly complex. From managing latency and power consumption to integrating cutting-edge software and hardware, modern automotive systems demand innovative solutions that ensure performance, reliability, and scalability.

This blog explores how VisualSim, a leading system-level simulation platform, addresses these challenges, enabling automotive engineers, E/E architects, and product managers to optimize their designs with unprecedented precision.

Understanding the Evolution of E/E Architecture

The shift from Distributed Architectures to Zonal and Centralized Architectures represents a significant change in how automotive systems are designed and managed.

  • Distributed Architecture: Traditionally used for simpler systems, this architecture relies on multiple ECUs distributed across the vehicle. While straightforward, it often struggles with increased power consumption and latency issues.
  • Zonal Architecture: This model centralizes functionality, reducing wiring and improving efficiency. It’s ideal for handling the growing complexity of modern vehicles.
  • Centralized Architecture: Representing the future of automotive design, this architecture consolidates computation into a few powerful ECUs, ensuring scalability and modularity while reducing costs.

VisualSim allows designers to compare these architectures, providing data-driven insights into cost, performance, and power trade-offs for specific use cases.

Design Challenges in Automotive Systems

The transition to advanced E/E architectures brings unique challenges across various components:

  • Latency and Power Efficiency: Measuring accurate latency and power consumption is crucial for ensuring real-time responses in systems like ADAS, safety, lighting and braking.
  • Hardware and Software Integration: Selecting and sizing the processors, peripherals and semiconductors, to execute the software task graphs is critical for efficient operation
  • Network Optimization: Ensuring low-latency and high-bandwidth communication is essential for electronics driven architecture.

By simulating these workloads at an early stage of the development, VisualSim identifies bottlenecks early in the design phase, enabling engineers to make informed decisions.

VisualSim’s Role in Automotive System Design

VisualSim is a powerful tool that accelerates the design and optimization of E/E architectures. Its unique features include:

  1. System-Level Simulation: VisualSim enables end-to-end modeling of hardware, software, and network components, providing a holistic view of the system.
  2. Rapid Architecture Trade-Offs: Designers can evaluate use cases, workloads, multiple configurations to balance latency, power, and computational resources.
  3. Bottleneck Detection: Through regression simulations, VisualSim identifies bottlenecks in latency and power consumption, guiding optimal task allocation.
  4. ISO 26262 Compliance: The platform validates safety standards and failure responses, ensuring compliance with key automotive regulations.

Case Studies: Real-World Applications of VisualSim

Denso optimize the Gateway ECU using hardware-software simulation

Denso was able to assemble models of the processors, interfaces, schedulers, buffers and power management to evaluate the latency and throughput for different real-life traffic traces from vehicles. This enabled Denso to accurately configure the Gateway for each car model and to accurately predict the expected latency.

Braking and Safety Systems

Using VisualSim, an automotive OEM assigned the sensors, ECU and gateways across the CAN and TSN network, enabling predictable response time from proximity sensor to wheel brakes.

EV Battery Management

For an electric vehicle, VisualSim was used to simulate battery usage of an infotainment system using the Nvidia GPU. The insights helped increase battery life cycle by 20% and the mileage.

Optimize ADAS allocation on multi-core Autosar

General Motors simulated the behavior of the ADAS task graph and mapped it to a network of ECUs running Autosar to capture the OS metrics and measure the OS buffering and the latency.

Future Trends in E/E Architecture

The automotive industry is rapidly adopting new technologies to address evolving demands:

  • AI-Driven Optimizations: Artificial intelligence is being used to enhance task scheduling and resource allocation, ensuring optimal performance in multi-core ECUs.
  • Centralized Architectures: By consolidating functions into fewer ECUs, centralized architectures are improving modularity and scalability, paving the way for smarter, more efficient vehicles.
  • Advanced Simulation Tools: Platforms like VisualSim are becoming indispensable for designers, enabling them to anticipate challenges and optimize systems before physical implementation.
