In MPSoC development environment, changes in the hardware architecture can bring in extensive re-partitioning or re-parallelization of the software architecture. Fast and accurate functional simulation and performance estimation techniques are needed to cope with this co-design problem at the early phases of MPSoC design space exploration. The current paper addresses this issue by introducing a framework which combines hybrid simulation, cache simulation and online trace-driven replay techniques to accurately predict performance of programmable elements in an MPSoC environment. The resulting simulation technique can easily cope with the continuous re-organizations of software architectures during an Instruction Set Simulator (ISS) based design process. Experimental results show that this framework can improve system simulation speed by 3-5X on average while achieving accuracy closely comparable to traditional ISSes.","PeriodicalId":412696,"journal":{"name":"2008 45th ACM/IEEE Design Automation Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116286020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we develop predictive models for estimating the performance of systems by using performance numbers from only a small fraction of the overall design space. Specifically, we first develop three models, two based on artificial neural networks and another based on linear regression. Using these models, we analyze the published Standard Performance Evaluation Corporation (SPEC) benchmark results and show that by using the performance numbers of only 2% and 5% of the machines in the design space, we can estimate the performance of all the systems within 9.1% and 4.6% on average, respectively. Then, we show that the performance of future systems can be estimated with less than 2.2% error rate on average by using the data of systems from a previous year. We believe that these tools can accelerate the design space exploration significantly and aid in reducing the corresponding research/development cost and time- to-market.","PeriodicalId":412696,"journal":{"name":"2008 45th ACM/IEEE Design Automation Conference","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128306052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of these effects usually requires atomistic simulations that are too expensive computationally for statistical circuit design. In this work, we develop an efficient SPICE simulation method and statistical transistor model that accurately predict threshold variation as a function of dopant fluctuations and gate length change caused by sub-wavelength lithography and gate etching process. By understanding the physical principles of atomistic simulations, we (a) identify the appropriate method to divide a non-uniform gate into slices in order to map those fluctuations into the device model; (b) extract the variation of Vth from the strong-inversion region instead of the leakage current, benefiting from the linearity of the saturation current with respect to Vth and (c) propose a compact model of Vth variation that is scalable with gate size and the amount of dopant and gate length fluctuations. The proposed SPICE simulation method is fully validated against atomistic simulation results. Given the post-lithography gate geometry, this approach correctly models the variation of device output current in all operating regions. Based on the new results, we further project the amount of Vth variation at advanced technology nodes, to help shed light on the challenges of future robust circuit design.","PeriodicalId":412696,"journal":{"name":"2008 45th ACM/IEEE Design Automation Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132725062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
