agileCAM
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, Samsung Foundry and SMIC as well as other IC foundries and manufacturers.
Input frequency: Up to 100 MHz • Relative frequency measurement capability • Relative frequency measurement resolution (frel) 1: 10kHz • Relative frequency measurement latency (trel) 1: 100μs • Detected clock attacks • Over-clocking • Under-clocking • Glitching • Holding/single-stepping • Integrated Calibration Mode • Silicon Area – 0.02 mm2 in GF12LP+
Digitally Wrapped: AMBA-APB Interface to simplify integration, testing and operation • Provided with System Verilog models DFT/DFM • Provision for scan chain insertion • Incorporated trim and calibration to facilitate process and/or manufacturing offsets to be adjusted • Built-in test mode
The agileCAM can be combined with the agileGLITCH, agileIRDROP, and agileDTSENSE to provide a comprehensive security macro monitoring for side-channel attacks on the device power supply, clock, and temperature.
