Clock Attack Monitor


product icon for Clock Attack Monitor

Product Overview

The agileCAM is a Ring Oscillator (RO) based clock attack monitor designed to detect clock attacks due to violation of the set-up time requirements of critical circuits. agileCAM can detect attacks based on changes in clock frequency, clock hold and clock glitch errors. Additionally, it provides a relative frequency measurement of the monitored clock with programmable alarm thresholds. The RO based scheme is easily configurable depending on the frequency of the input clock and provides an area and power efficient solution. The agileCAM requires calibration and storage of the RO oscillation frequency at ATE testing of the device.

Agile Analog designs are based on tried and tested architectures to ensure reliability and functionality. Our design methodology is programmatic, systematic, and repeatable, leading to analog IP that is more verifiable, more robust, and more reliable. Our methodology also allows us to quickly re-target our IP to different process options. We support all the major foundries including TSMC, GlobalFoundries, Intel Foundry, Samsung Foundry, UMC and Other Foundries.
