What if a digital circuit could detect its own faults, correct errors during operation, and keep running without interruption? A new soft IP aims to make that possible.
GreenIPCore has launched its Fault Detector Soft IP, a digital IP block designed to detect, manage, and correct faults in digital circuits during runtime. The soft IP can be implemented in FPGA, CPLD, and ASIC designs, enabling systems to identify and respond to transient faults and soft errors that may otherwise compromise circuit operation.
The Fault Detector continuously monitors its own circuitry and generates a dedicated output signal whenever a fault is detected. Unlike conventional monitoring approaches, the IP is designed to preserve correct logical operation even when faults occur within its internal logic. According to the company, the architecture incorporates built-in fault detection, management, and correction mechanisms that allow the circuit to continue operating correctly while identifying fault events.
A key feature of the IP is its ability to provide both fault awareness and fault tolerance within a compact logic implementation. The company states that the design can detect faults affecting internal digital logic while automatically correcting the resulting soft errors, helping prevent error propagation through the system.
The IP is synthesizable and portable across multiple FPGA and ASIC technologies, allowing integration into a wide range of digital designs. It can also be connected to system-level monitoring and control architectures through standard digital interfaces.
GreenIPCore notes that the technology is intended for applications operating in environments where electromagnetic interference (EMI), electromagnetic compatibility (EMC) issues, radiation effects, or transient disturbances can introduce faults into digital circuitry. Potential use cases include industrial control systems, automotive electronics, aerospace and defense platforms, robotics, communications equipment, and IoT devices.
By combining runtime fault detection, self-correction capabilities, continuous monitoring, and technology-independent implementation, the Fault Detector Soft IP aims to help designers improve system reliability without requiring major changes to existing digital architectures.
