Concurrent Multi-Channel Crosstalk Jitter Characterization Using Coprime Period Channel Stimulus

In recent years, the use of highly parallelized and high-speed data links has exacerbated the problem of crosstalk coupling. Signals with high frequency components couple to and degrade the quality of signals in adjacent lines aggressively with …

High Resolution Pulse Propagation Driven Trojan Detection in Digital Logic: Optimization Algorithms and Infrastructure

Insertion of malicious Trojans into outsourced chip manufacturing generally results in increased capacitances of internal circuit nodes that have been tapped for node controllability and observability by malicious circuitry. Current path delay …

VAST: Post-Silicon VAlidation and Diagnosis of RF/Mixed-Signal Circuits Using Signature Tests

Post-silicon validation of RF/mixed-signal circuits is challenging due to the need to excite all possible operational modes of the DUT in order to establish equivalence between its specified and observed behaviors and to ensure that the DUT does not …

Validation Signature Testing: A Methodology for Post-Silicon Validation of Analog/Mixed-Signal Circuits

Due to the use of scaled technologies, high levels of integration and high speeds of today's mixed-signal SoCs, the problem of validating correct operation of the SoC under electrical bugs and that of debugging yield loss due to unmodeled …
