Problem Statement/Challenges:

Our client, a leading home automation company, required a highly efficient, lowpower VLSI design to integrate into their new line of smart home security systems. Their goal was to enhance the energy efficiency of their products without compromising performance or security. The primary challenges included:

  1. Power Consumption: The client needed a solution that would significantly reduce power consumption to make the system suitable for battery-operated devices.
  2. User-Friendly Design: The system needed to be easy to use for the average consumer, facilitating seamless integration with existing home systems.
  3. Security: Ensuring robust security features to protect against unauthorized access and data breaches.

High-Level Solution:

We proposed a VLSI design leveraging the RISC-V architecture, known for its flexibility, scalability, and low power consumption. The design included advanced security features such as AES, RSA, and SHA-2 hardware accelerators, secure boot processes, and on-chip secure memory.

Design Quality:

The design process focused on creating high-quality, robust ASICs capable of withstanding the rigorous demands of automotive environments. Key aspects included:

  1. Architecture: Shakti C-Class 64-bit RISC-V Core with 700 MHz clock frequency for high-performance processing.
  2. Power Efficiency: Optimized for low power usage with low core (0.9V) and I/O (1.8V) voltages.
  3. Security: Comprehensive suite including AES, RSA, SHA-2, secure boot, onchip secure memory, and TRNG.
  4. Peripheral Support: Extensive GPIOs, multiple serial interfaces, and a 12-bit SAR ADC with 8 channels.

Pre-Silicon Testing:

We conducted extensive simulations and verification processes to ensure the design met the client’s requirements. Functional verification, power analysis, and security testing were performed to validate the design’s performance and reliability.

Prototype Testing:

Prototypes were developed and subjected to rigorous testing, including functional tests, power consumption measurements, and security evaluations. The prototypes demonstrated significant improvements in power efficiency and robust security features, aligning with the client’s expectations.

Client Testing:

The final prototypes were delivered to the client for integration and field testing. The client conducted extensive real-world tests, confirming the system’s low power consumption, enhanced security, and user-friendly operation. The product received positive feedback for its performance and reliability in various home automation scenarios.

Conclusion:

NanoGenius Technologies Pvt. Ltd. successfully delivered Low-Power VLSI Design Solution that met the client’s stringent requirements for their Home Automation & Security System.
