Design And Reuse. However there is no automated utility to identify and fix these issues on test patterns prior to handoff to PE team causing schedule delay.

This paper introduces a unified DFT - PE Methodology, aimed at providing a complete, methodical and fully automated path addressing gaps between DFT and PE team ensuring quick turnaround time in silicon validation. The methodology used in this paper significantly improved the cycle time for silicon validation using low cost tester. This paper start with introduction section which describes critical WIMAX Worldwide Interoperability for Microwave Access silicon validation issues experienced over last two years and highlights the need for unified methodology to overcome these issues.

Summary of silicon validation issues described in this section are based on lessons learned between design team, product engineering team and analog IP team. The next section provides details on solution offered in this paper. This section describes details on how proposed methodology overcomes limitations mentioned in the introduction section.

It lists features, benefits of this utility and depicts the implementation details to the user. What passes in simulation may not necessarily pass in silicon on tester. Assumption that some IP did not change from previous version of the project to new version of the project resulted in incomplete review from IP owner e.

This caused major problem with functional fail due to incorrect sdf Standard Delay Format annotation resulting in interface level timing issue. This resulted in multiple TDL handoff and tester debug time to meet the shutdown power requirement as per specification. The methodology presented in this paper attempts to address these issues and provides a workable solution.

The DFT Methodology proposed in this paper is defined into three separate sections: First section is rule based utility which implements some of these lessons learned ensuring completeness of DFT closure. Implementation Details This section depicts the implementation details, highlighting features and benefits. Allows the user to select the rules and run it on either individual files or complete directory. Benefits: Improves quality of test pattern deliverable and supports early silicon bring up.

Saves time due to manual effort of correcting individual TDL patterns prior to handoff. Less prone to error since the rules are validated and automated as compared to manual update which is dependent on experience of DFT engineer.

Modular rules structured as functions allowing new rules to be added with ease Figure1. Snapshot of TDL Rules. Summarizes overall score, providing useful insight to the user on improvement areas. Benefits: Ensures past mistakes are not repeated: All lessons learned from past projects are incorporated as part of checklist reducing human error due to change in engineering teams.

Snapshot of QC Checklist C. Supports easy document update to central repository. Benefits: Promotes usage of best practices from past lessons learned. Snapshot of Document Repository. Score based methodology to give useful insight on completeness of QC process.

His research interests include embedded and cyber-physical systems, energy-aware computing, hardware security and trust, system-on-chip verification, bioinformatics, and post-silicon validation and debug. He received his Ph. He has published six books and more than research articles in premier international journals and conferences. Farimah Farahmandi received her Ph. She received her B. Her research is focused on developing analytical models and computational methods for design and verification of secure, trustworthy and energy-efficient systems. During her Ph.

While developing semiconductors, post-silicon validation is an important step to identify the errors that are not detected during the pre-silicon verification and manufacturing testing phases. When the design complexity increases, the required debug time also increases because additional debug data are required to identify the errors. In this study, we present a debug scheme that improves the error identification capability. The proposed debug approach concurrently generates three types of signatures using hierarchical multiple-input signature registers MISRs. The error-suspect debug cycles are determined by analyzing the debug cycles that are commonly contained in the erroneous signatures of the three MISRs.

Post-Silicon Validation and Debug

Rising costs, tighter market windows and more heterogeneous designs are forcing chipmakers to rethink fundamental design approaches. In the past, chipmakers typically banked on longer product cycles and multiple iterations of silicon to identify problems. This no longer works for several reasons:. Put simply, chipmakers are under pressure to do more, in less time, for the same or less money. The reason the product cost is shooting up is integration and software.
