A common way to reduce the static power consumption of an SRAM array is to decrease its supply voltage when in memory retention mode. Decreasing the supply voltage however has a strong negative effect on the stability of the SRAM cell. This paper statistically analyzes the behavior of the 6T SRAM cell in data retention mode, under process variability. The failure probabilities under various supply voltages are determined for different technology nodes, and the Data Retention Voltage is determined. For the 45nm PTM SRAM cell under random threshold voltage variation, the Data Retention Voltage is found to be 423mV while for the 16nm PTM SRAM, the DRV is 649mV.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116947982","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 paper, an investigation of a TRNG design based on several oscillator rings implemented in a field programmable gate array (FPGA) is performed in order to determine the amount of true randomness or entropy in this design. A model of the TRNG based on the number of hits in the transition regions generating entropy is proposed. This model takes into account the fact that the jitter of an oscillator ring is not constant, but increases or accumulates if the ring is not sampled in a region close to a transition point where the oscillator ring output changes from logic 0 to logic 1 or vice versa. The model of the TRNG is implemented in MatLab and simulations are performed showing the influence of different design parameters and also the influence of properties of the FPGA device on quality of randomness.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"14 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130863","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}

Due to the communication complexity of such systems it is difficult to estimate the communication delay. On the other hand, guaranteeing the timing constraints without detailed know-how about the communication is impossible. In this work we propose a communication modelling and synthesis approach for networks-on-chip where communication infrastructure is not able to provide communication interleaving (such as TDMA, virtual channels) or to guarantee communication delays. The idea is, to design a communication synthesis method, which would not be run off-chip as a CAD tool on a workstation, but on-chip and being activated whenever the system-on-chip (SoC) is re-configured.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129138404","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 conventional technique for improving system reliability is through component replication, which usually comes at significant cost: increased design time, testing, power consumption, volume and weight. In this contribution, we propose a technique based on partial dynamic reconfiguration (PDR) to tolerate faults in configurable logic blocks (CLBs) and routing resources (RRs). The fault tolerance is achieved through SRAM cells of configuration frames. Our method do not require preallocated spare CLBs or RRs. The reliability of frames is analyzed and improved.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126231392","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}

Thus such tests may cause test escapes as they may not adequately stress the circuits under test. In this work we propose a method called Max-Fill to generate high quality partially-functional broadside delay tests. The generated tests are shown to cause switching activity close to the switching activity during functional operation. The method computes a set of reachable states in which states are likely to cause high switching activity. During test generation phase, these states are used as background states to fill the unspecified bits of test cubes. Additionally, the number of test patterns produced is less than that produced by low power test methods. Experimental results for ISCAS-89 circuits are given.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133427299","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, the physical contact occurring between the wafer and automatic test equipment (ATE) has significant costs due to contact point deformation and the need for abrasive cleaning. In this paper, we investigate a non-contact testing technique that wirelessly couples an IC wafer and ATE, and serves as an alternative to conventional probe-card testing. We derive several analytical models for a capacitive testing channel. Electromagnetic field simulations results are presented that support the proposed channel models. We conclude that capacitance-based wireless testing is feasible for testing ICs in the 1-GHz range.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132200224","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}
