Abstract
Post-silicon validation of complex System-on-Chip (SoC) architectures has become an indispensable phase in modern integrated circuit development, owing to the increasingly sophisticated interaction of digital logic, embedded memory, and heterogeneous processing units. The limitations of pre-silicon verification methodologies, including formal verification and simulation, necessitate robust post-silicon debugging techniques that are capable of isolating, reproducing, and analyzing elusive design flaws in silicon hardware. This research synthesizes contemporary approaches in post-silicon debug infrastructure, with a particular focus on reconfigurable design-for-debug (DfD) methodologies, failure propagation tracing, and the integration of formal methods with embedded logic analysis. Grounded in foundational contributions by Abramovici et al. (2006), who proposed a reconfigurable DfD framework for SoCs, this study critically examines the theoretical underpinnings, practical implementations, and comparative efficacy of various post-silicon debug strategies. Additionally, advanced topics such as lossless compression of debug data (Anis & Nicolici, 2007), runtime assertion checking (Boule & Zilic, 2005), and formal backspace analysis techniques (de Paula et al., 2008) are explored to provide a comprehensive framework for evaluating and improving post-silicon validation pipelines. Through descriptive and analytical synthesis of empirical findings across multiple studies, this article elucidates the inherent trade-offs between resource utilization, observability, and fault localization granularity. The discourse further contextualizes these techniques within the broader landscape of SoC design verification, highlighting emergent opportunities for integrating machine-assisted inference, SMT-based reasoning (Barrett et al., 2009), and runtime model checking (Bayazit & Malik, 2005). By bridging historical methodologies with contemporary advancements, the article offers actionable insights for hardware engineers, test architects, and design verification scholars seeking to enhance the reliability, performance, and diagnostic efficiency of post-silicon debugging processes.
