A Signal-Integrity Self-Test Concept for Debugging Nanometer CMOS ICs

A fully integrated signal-integrity self-test concept is implemented in a 90nm CMOS process. The outputs of different analog monitors are locally converted to digital form and then transported through a test-compatible scan chain. The temperature monitor has 4b resolution. The supply-noise monitor detects 10ps-wide pulses of 20mV. The total area overhead is <0.1%
