Unified Coverage Methodology for SoC Post-Silicon Validation

New Algorithms and Architectures for Post-silicon Validation New Algorithms and Architectures for Post-silicon Validation

To identify design errors that escape pre-silicon verification, post-silicon validation is becoming an important step in the implementation flow of digital integrated circuits. While many debug problems are tackled on testers, there are hard-to-find design errors that are activated only in-system. A key challenge during in-system debugging is to acquire data from internal circuit’s nodes in rea...

A Methodology for SoC Top-Level Validation using Esterel Studio

In this paper, we suggest a methodological framework addressing the System on Chip top-level validation. Our systematic approach works on a powerful abstraction of IP blocks called transactional model. We state the transactional modeling “philosophy”, its benefits, and its limitations. The methodology is illustrated step by step on a simplified example. Its effective implementation is realized ...

Coverage-Based Trace Signal Selection for Fault Localisation in Post-silicon Validation

Post-silicon validation is the time-consuming process of detecting and diagnosing defects in prototype silicon. It targets electrical and functional defects that escaped detection during pre-silicon verification. While the at-speed execution of test scenarios facilitates a higher test coverage than pre-silicon simulation, this comes at the cost of limited observability of signals in the integra...

Coverage Driven Methodology for Verification of SoC Hardware and Software Corner Cases

SoC Methodology an Overview

System on a Chip (SoC) is a concept that has been challenging the traditional design flow methodologies by: encouraging component reutilization; promote concurrent development; propose new design, verification and validation flows; encourage innovation; and enable multidisciplinary teams to work together. Rather than being a hard recommendation for an specific SoC methodology, the objective of ...
