The model exhibits reasonable accuracy as compared to SPICE. The regions where ground coupling and source/drain coupling dominate are described based on this model. The impact of multiple parameters such as the rise time, number of switching gates, decoupling capacitance, and parasitic inductance on the dominant noise coupling mechanism is investigated. The dominance of ground coupling in large scale circuits, as generally assumed, is shown to be invalid if sufficient decoupling capacitance is used or the circuit exhibits a low parasitic inductance such as a flip-chip package. The efficacy of several noise reduction techniques is discussed based on the application of the dominant noise analysis model.","PeriodicalId":243121,"journal":{"name":"9th International Symposium on Quality Electronic Design (isqed 2008)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117303612","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}

By using this technique, we explored the design margin of SPRAM cell with one-transistor-one-MTJ (ITU) structure.

Coupling induced crosstalk may induce unwanted noise on coupled signal nets resulting in functional failure and performance degradation and becomes a significant limitation in achieving first pass silicon success. At the same time the complexity of noise analysis has significantly increased due to factors such as driver weakening, IR drop, power network switching, voltage scaling and variations in manufacturing processes. Therefore validating the capabilities and verifying the analysis of a crosstalk analysis tool for current and future process nodes is very critical for efficient and accurate signoff analysis. The modeling of the cell itself needs to be accurate and comprehensive. The objective of the paper is to share the methodology and challenges involved in crosstalk noise analysis and how the composite current source (CCS) based crosstalk noise analysis capability of primetime SI would help us achieve many of our goals.","PeriodicalId":243121,"journal":{"name":"9th International Symposium on Quality Electronic Design (isqed 2008)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126515733","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}

However, it can't avoid the storage explosion introduced by the explosion of the BDD sizes for large designs. For scalability, we introduce two kinds of decomposition techniques: One is the equivalence checking oriented program slicing; the other is the hierarchical insertion of logic cut- points. And a 2D decomposition SEC method of SLM-vs.-RTL is presented. \"2D decomposition\" means decomposition in the space dimension and the time dimension. The verification model is only built for the program slices of a single output variable for each time, which limits the usage of memory. During checking the equivalence of the program slices, the logic cutpoints are inserted to split the verification model of the program slices in the time dimension, which controls the storage explosion further. The promising experimental results demonstrate the benefits brought by our 2D decomposition method.","PeriodicalId":243121,"journal":{"name":"9th International Symposium on Quality Electronic Design (isqed 2008)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126740186","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 semiconductor revenue has been about $33B. The ASP is declining, both in the wireless phone and semiconductor industry. In order to fix that, Moore's Law is being inverted: instead of getting twice the transistors for the same cost, the wireless phones industry seeks to obtain the same number of transistors for half the cost. This is making system-on-chip (SoC) no longer a viable solution. System-in-package (SiP) looks much more promising. Lack of EDA solutions - especially the A of automation - has so far slowed down the ramp-up of SiP. In this paper we describe the landscape and present a SiP platform solution which addresses the challenges of simplification, cost reduction, quality and reliability improvement, yet allowing exploiting the most recent advances in IC packaging.","PeriodicalId":243121,"journal":{"name":"9th International Symposium on Quality Electronic Design (isqed 2008)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115820401","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}

Climate change is occurring all around us, and the scientific evidence is increasingly overwhelming pointing to man's hand in the phenomena. We are already seeing huge impacts of Climate Change, much faster than anybody predicted, only a few short years ago. What can we do about? How can we slow and even reverse our impact on Climate Change? The key man made contributing factor is carbon emissions, primarily from coal fired power plants. We need to reduce the number of plants that we building, then the number of power plants that we require.The key to this is a reduction in power consumption.There are many everyday actions we can take individually to help. Al Gore states that Global Warming is an engineering problem that will be solved by engineers, addressing the issue as an opportunity, rather than additional cost. We will explore how engineers will impact Climate Change. Low power IC design techniques will play a role in this just as new powerful techniques are coming into vogue.","PeriodicalId":243121,"journal":{"name":"9th International Symposium on Quality Electronic Design (isqed 2008)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122110349","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}

We then utilize the signature variables during the fault propagation in a way such that the latched error propagates robustly to an observable point irrespective of other latched errors.
