Watchdog Timer
Design IP
Overview

SmartDV’s Watchdog Timer IP is a robust, silicon-proven solution designed to enhance system reliability by detecting and recovering from software anomalies or system hangs. Ideal for safety-critical applications in automotive, industrial, and embedded systems, it provides continuous monitoring of processor activity and triggers corrective actions when system responsiveness is lost.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. It supports programmable timeout intervals, windowed watchdog operation, and system reset or interrupt generation—making it a dependable safeguard for fault-tolerant designs.
