Microelectronics world news

The automotive industry is facing significant technological challenges in developing new and innovative features and services. When defining their products, vehicle manufacturers must anticipate future technical advancements in microelectronic platforms, sensors, and semiconductor technologies. At the same time, suppliers and semiconductor manufacturers need early insights into the requirements for upcoming features and services to be able to invest in technology development with confidence.

As part of the “GENIAL!” project funded by the Federal Ministry of Education and Research (BMBF), eleven partners collaborated to develop concepts and methods that help companies in the automotive industry work together more effectively and prepare for the future. The project specifically focused on optimizing the collaboration between automotive manufacturers and their component and technology suppliers to accelerate innovation across the automotive value chain.

The prototypical automotive microelectronics roadmap developed in GENIAL! provides a strategic framework for identifying future market needs, use cases, system models, and technical requirements in the field of automotive microelectronics. This roadmap establishes a shared understanding of the microelectronics requirements of future highly innovative vehicles across the entire value chain. The results enable all market participants, as well as research institutions and policymakers, to manage investments and research activities more effectively. In turn, this facilitates the implementation of significantly shorter and more reliable development processes, allowing new, innovative automotive components to be realized more quickly.

The project was based on a model-based system development approach that utilizes the Systems Modeling Language (SysML) as a modeling language, now integrated into SysML v2. This approach is supported by the AGILA database and further enhanced by the IRIS (Interactive Roadmapping of Innovative Systems) tool, both developed within the project. AGILA serves as a centralized database for capturing the essential information and providing documentation, consistency checks, and version control.

The IRIS tool enables collaborative modeling, exploration, planning, and evaluation of solution alternatives. It also supports non-technical information, allowing considerations such as security of supply, and enables visualizations for roadmapping. To encourage widespread adoption, the project participants will release tools such as AGILA and IRIS as open-source solutions, making them accessible for anyone interested in creating and maintaining roadmaps.

The innovation modeling methodology “IMoG” (Innovation Modelling Grid) defines activities, roles, and process models for the collaborative creation of roadmaps. This spans from the initial comparison of models in the problem and solution space to the practical application of the AGILA and IRIS tools. Documentation of the methodology, along with several training videos, is available for free download.

The Convergence of Quantum and Classical Technologies

The field of computing is undergoing a transformative shift with the advent of quantum computing. While classical electronics have been the backbone of digital technology for decades, quantum computing promises to unlock unprecedented computational capabilities. However, these two paradigms are not mutually exclusive; rather, they can complement each other, leading to more efficient and powerful computing architectures. This article explores the latest developments in integrating quantum computing with classical electronics, detailing the technical challenges, innovative solutions, and future implications.

The Foundations: Understanding Classical and Quantum Computing Classical Electronics: The Workhorse of Modern Computing

Classical computing is built on the foundation of semiconductor-based electronics, primarily leveraging transistors, integrated circuits, and Boolean logic. It operates on bits, which can either be in the state of 0 or 1, and relies on deterministic algorithms to process information.

Quantum Computing: The Next Frontier

Quantum computing introduces a fundamentally different approach, utilizing qubits instead of bits. Qubits can exist in superposition, meaning they can represent both 0 and 1 simultaneously, and leverage entanglement for highly efficient parallel computations. This enables quantum systems to solve problems that are infeasible for classical computers, such as complex optimizations, cryptographic analysis, and molecular simulations.

Bridging the Gap: Integrating Quantum and Classical Systems

Quantum processors (QPUs) do not operate in isolation; they require classical electronics for control, measurement, and data processing. The integration of these two domains is critical to making quantum computing practical and scalable.

Classical Control of Quantum Systems

• Cryogenic CMOS Electronics: Since qubits operate at extremely low temperatures (near absolute zero), classical control electronics must function reliably at cryogenic conditions. Innovations in cryogenic CMOS technology enable signal processing and qubit manipulation without excessive thermal noise.
• High-Speed Digital-to-Analog and Analog-to-Digital Converters (DAC/ADC): These components are crucial for translating classical instructions into precise qubit operations and reading quantum state measurements.
• Low-Latency Error Correction: Quantum error correction requires real-time classical processing to mitigate decoherence and maintain computational accuracy. Specialized classical processors are being developed to handle these operations efficiently.

Quantum-Classical Hybrid Algorithms

Many quantum algorithms require classical pre- and post-processing. Examples include:

• Variational Quantum Eigensolver (VQE): Used in quantum chemistry, where a classical optimizer adjusts quantum circuit parameters to minimize energy states.
• Quantum Approximate Optimization Algorithm (QAOA): A hybrid approach that leverages quantum computation for complex combinatorial problems while using classical methods for optimization refinement.

Challenges in Quantum-Classical Integration Scalability Issues

As quantum processors scale up, the overhead on classical electronics increases significantly. The interconnect complexity, power consumption, and latency must be optimized to handle thousands of qubits efficiently.

Heat Dissipation

Operating classical electronics near quantum processors requires careful thermal management to prevent interference with qubit coherence. New materials and low-power circuit designs are being explored to address this issue.

Data Transfer Bottlenecks

Quantum computations generate vast amounts of data that must be efficiently transferred to classical processors for analysis. Advanced data compression and high-speed interconnects are being developed to enhance performance.

Emerging Solutions and Innovations Photonic Interconnects

Optical communication is being explored to connect classical and quantum systems with minimal signal degradation. Photonic links enable faster and more reliable transmission of control signals and readout data.

Neuromorphic Computing for Quantum Error Correction

Neuromorphic processors, which mimic the human brain’s neural networks, are being investigated to handle real-time quantum error correction more efficiently than traditional digital processors.

AI-Assisted Quantum Control

Machine learning algorithms are being integrated into quantum control systems to optimize pulse sequences, error correction strategies, and system calibrations dynamically.

Future Directions: Towards a Quantum-Classical Hybrid Era

The future of computing lies in a seamless fusion of quantum and classical technologies. Research is progressing towards developing quantum-classical hybrid architectures that harness the best of both worlds. Potential advancements include:

• On-Chip Integration: Embedding quantum and classical components onto the same chip to reduce latency and improve scalability.
• Fault-Tolerant Quantum Systems: Advancements in quantum error correction that minimize the need for excessive classical post-processing.
• Cloud-Based Quantum Computing: Platforms where classical systems offload computationally intensive tasks to quantum processors over high-speed networks.

Conclusion: The Road Ahead

The integration of quantum computing with classical electronics represents a monumental leap in computational capabilities. By overcoming current technical challenges, researchers are paving the way for a new era of computing where quantum and classical systems work in unison to solve the most complex problems. The convergence of these technologies will not only drive breakthroughs in artificial intelligence, materials science, and cryptography but also redefine the limits of human knowledge and innovation.

An intro to RISC-V

As safety-critical systems become increasingly complex, the choice of processor architecture plays an important role in ensuring functional safety and system reliability. Consider an automotive brake-by-wire system, where sensors detect the pedal position, software interprets the driver’s intent, and electronic controls activate the braking system. Or commercial aircraft relying on flight control computers to interpret pilot inputs and maintain stable flight. Processing latencies or failures in these systems could result in unintended behaviors and degraded modes, potentially leading to fatal accidents.

The RISC-V architecture’s inherent characteristics—modularity, simplicity, and extensibility—align with the demands of functional safety standards like ISO 26262 for automotive applications and DO-178C for aviation software. Unlike proprietary processor architectures, RISC-V is an open standard instruction set architecture (ISA) developed by the University of California, Berkeley, in 2011. The architecture follows reduced instruction set computing (RISC) principles, emphasizing performance and modularity in processor design.

RISC-V is set apart by its open, royalty-free nature combined with a clean-slate design that eliminates the legacy compatibility constraints of traditional architectures. The ISA is structured as a small base integer set with optional extensions, allowing processor designers to implement only the features needed for their specific applications.

This article examines the technical advantages and considerations of implementing RISC-V in safety-critical environments.

Benefits for safety-critical industries

Traditional proprietary architectures, such as Arm, have served safety-critical industries well, but challenges around supplier diversity, customization needs, and safety certification requirements have driven interest in RISC-V.

The following sections describe characteristics of RISC-V that make it a viable option for safety-critical development teams.

Architectural independence

One fundamental challenge in developing safety-critical systems is mitigating supply chain risks. Traditional processor architectures require licensing agreements and create vendor lock-in, which impacts long-term system maintainability and cost.

RISC-V’s open model provides several advantages. The ability to work with multiple silicon vendors reduces single-point-of-failure risks in the supply chain. This is particularly important for long-lifecycle applications in aerospace and automotive, where systems may need to be maintained and supported for decades. When using RISC-V, manufacturers expand their options for semiconductor suppliers and development tool ecosystems, providing flexibility in responding to supply chain issues.

Customization to meet safety-critical requirements

RISC-V’s modular design philosophy allows silicon vendors and system architects to implement custom features at the hardware level. This capability helps address specific safety requirements across mission-specific applications certification standards such as:

• Custom error detection and correction.
• Hardware-level monitoring and diagnostic capabilities.
• Low-latency, deterministic execution features for real-time requirements.

Additionally, RISC-V silicon vendors have products supporting harsh environments, such as processors with radiation hardening and electromagnetic pulse (EMP) protection for space applications.

Memory management

One of RISC-V’s distinguishing features is its approach to cache memory management, helping developers of safety-critical applications requiring deterministic behavior. The ability to implement level 2 cache memory mapping as RAM gives developers greater control over system latency, a crucial factor in real-time safety-critical applications.

This capability addresses challenges covered in aviation safety guidelines like EASA AMC 20-193 and FAA AC 20-193. By providing better solutions for cache contention mitigation than traditional architectures, RISC-V supports more predictable execution timing—a critical requirement for safety certification.

Dissimilar redundancy

Safety-critical systems requiring design assurance level A (DAL-A) certification under DO-178C often implement redundancy to protect against common mode failures. RISC-V’s open architecture provides advantages in implementing dissimilar redundancy strategies:

• Implementation of different processor configurations within the same system.
• Diverse redundancy schemes using different vendor solutions.
• Using different architectures in mixed-criticality systems with varying levels of safety requirements.

Performance considerations

While RISC-V may not always match the raw performance metrics of modern Arm implementations, its architecture provides several advantages specific to safety-critical applications. The ability to implement custom instructions and hardware features allows optimization for specific safety requirements without compromising overall system performance.

Key performance-related features include:

• Deterministic execution paths for real-time applications.
• Custom instructions for safety monitoring.
• Efficient context switching for mixed-criticality systems.
• Configurable memory protection units to minimize stack and data corruption.

RISC-V’s development tool ecosystem

Over the years, the maturation of development tools and verification environments for RISC-V has expanded to cover the entire software lifecycle. For example, LDRA’s target license package (TLP) for RISC-V architectures supports development and on-target testing with multi-core code coverage analysis, worst-case execution time (WCET) measurement for AMC 20-193 compliance, requirements traceability, and integration with major RISC-V development platforms. This TLP makes RISC-V ready for safety and security.

Additionally, LDRA is highly integrated with RISC-V environments, supporting dynamic testing with hardware and commercial and open-source simulation environments, including silicon-level simulation. These environments support comprehensive hardware-accurate testing and verification to develop and test software as the hardware is developed.

Industry momentum around RISC-V

A growing number of safety-certified RISC-V IP cores offer designers pre-verified components that meet stringent safety requirements. Microchip, SiFive, CAST, and other vendors have released specialized RISC-V implementations with integrated safety features, fault detection mechanisms, and redundancy capabilities tailored for automotive and aerospace applications. Vendors such as Frontgrade Gaisler add to this with radiation-hardened microprocessors and IP cores for space-based systems.

The mix of industry support, technical guidelines, and certification tools creates a positive feedback loop that accelerates RISC-V adoption in safety-critical systems, making it increasingly attractive for organizations developing next-generation applications.
