Agile Analog has successfully delivered a robust anti-tamper solution to a prominent fabless
semiconductor company in Taiwan. As part of this deployment, the Agile Analog team provided
a suite of highly configurable, multi-process analog security IP, including its newly developed
Clock Attack Monitor (agileCAM), an enhanced Voltage Glitch Detector (agileVGLITCH), a
Digital Temperature Sensor (agileTSENSE_D), and an IR Drop Detector (agileIRDROP). These
components work together to equip a data center application with advanced security measures
for detecting and preventing tampering attempts.


Headquartered in Cambridge, UK, Agile Analog employs a groundbreaking approach to analog
IP development, leveraging automated technology to create solutions tailored to customers’
exact specifications, compatible with any foundry and process. These fully verified, digitally
wrapped solutions span key areas such as data conversion, power management, IC monitoring,
security, and always-on IP, ensuring seamless integration into any SoC design. The versatility of
these IP products enables their use in a wide range of applications, including High-Performance
Computing (HPC), Artificial Intelligence (AI), Internet of Things (IoT), and security-focused
systems.


Key Components of the Anti-Tamper Solution

1. agileCAM – A newly introduced mixed-signal ring oscillator-based Clock Attack Monitor
designed to detect clock-related tampering, including frequency shifts, clock hold, and clock
glitch errors. It features programmable alarm thresholds for precise frequency monitoring.

2. agileVGLITCH – An enhanced Voltage Glitch Detector that safeguards against voltage
side-channel attacks (SCAs) and tampering. With programmable glitch threshold levels and
nanosecond-resolution detection capabilities, it offers superior protection against voltage-based
intrusions.

3. agileTSENSE_D – A Temperature Sensor with an integrated digitizer that delivers digital
output. Agile Analog’s proprietary temperature sensor architecture achieves higher accuracy
while consuming less power than competing solutions. Temperature monitoring is essential
for detecting security breaches and optimizing power, performance, and area (PPA).

4. agileIRDROP – An IR Drop Sensor designed to identify power loss or potential power supply
attacks. This sensor includes a voltage reference and comparators configured with multiple
threshold levels, enabling multi-level detection for enhanced security.


Together, these customizable analog IP products form a comprehensive anti-tamper solution,
continuously monitoring power supply, clock integrity, and temperature fluctuations to identify
signs of potential security threats.
