Dacota: Post-silicon validation of the memory subsystem in multi-core designs

Andrew DeOrio, Ilya Wagner, Valeria Bertacco
2009 2009 IEEE 15th International Symposium on High Performance Computer Architecture  
The orders-of-magnitude faster testing in post-silicon enables designers to achieve much higher coverage before customer release, but only if the limitations of this technology in diagnosis and internal  ...  In this work, we unlock the full performance of postsilicon validation through Dacota, a new high-coverage solution for validating memory operation ordering in CMPs.  ...  Runtime solutions to the problem of memory subsystem correctness have emerged to ensure the correctness of multi-core designs deployed in the field. Meixner et. al.  ...

Post-silicon debugging for multi-core designs

Valeria Bertacco
2010 2010 15th Asia and South Pacific Design Automation Conference (ASP-DAC)  
Finally we present some of today's general trends in post-silicon validation research.  ...  Escaped errors in released silicon are growing in number due to the increasing complexity of modern processor designs and shrinking production schedules.  ...  The second solution focuses on the validation of the memory subsystem in multi-core designs, specifically of the cache coherence protocol.  ...

Accelerating trace computation in post-silicon debug

Johnny J.W. Kuan, Steven J.E. Wilton, Tor M. Aamodt
2010 2010 11th International Symposium on Quality Electronic Design (ISQED)  
Post-silicon debug comprises a significant and highly variable fraction of the total development time for large chip designs.  ...  To accelerate post-silicon debug, BackSpace [1, 2] employs on-chip monitoring circuitry and off-chip formal analysis to provide a trace of states that lead up to a crash state.  ...  This work was funded by the Semiconductor Research Corporation(SRC) TaskID: 1586.001.  ...
