With continued scaling, operating voltage levels have reduced and resultant decrease in noise margins, the possibility of transient faults is likely to increase. Also, during operation in adverse environments, transient faults occur upon exposure to ionizing radiations and neutron effects. These faults manifest themselves as unidirectional errors. The ability to operate in the intended manner even in the presence of faults is an important objective of all electronic systems. Totally Self-checking (TSC) circuits permit online detection of hardware faults. The Scalable Error Detection Coding (SEDC) technique used to design self-checking circuits with faster execution and lesser latency overhead for use in fault-tolerant VLSI circuits is presented. SEDC technique is formulated and architecture is designed in such a way that for any input binary data length, only area is scaled, with a constant latency of two logic gates and requires only a single clock cycle for generating SEDC code. It is shown that the proposed SEDC technique is found to be significantly efficient than the existing unidirectional error detection techniques in terms of speed, latency, area and achieving 100% error detection.","PeriodicalId":198881,"journal":{"name":"Fifth Asia Symposium on Quality Electronic Design (ASQED 2013)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126337552","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 testing methodologies will not be sufficient for the recently proposed and highly scalable Micro-electrode-dot array (MEDA) architecture based digital microfluidics. This is because of the advanced fluidic movement operations incorporated in the MEDA architecture.

Experimental measurement with Thermal Transient Tester (T3Ster) is performed to capture the thermal transient characteristic of the LED system. The simulation is conducted with FloEFD 12.1 CFD software, using two-resistor model the LED package is defined with thermal resistance at different forward current.

Pulsed-FFs are promising candidate for high-speed and low-power applications, thanks to their small data-to-output delay and their shareable PG. However, UWVR circuits work most of the time under the threshold voltage, where local variations lead to a huge spread in logic delays. Therefore, the designers have to ensure that the minimum width of the pulse signal activating the pulsed-FF is large enough to guarantee the correct functionality of the FF. On the other hand, a too large pulse window would lead to an increase of the hold time, and thus energy overhead for inserting delay buffers, which is not acceptable in energy-efficient circuits. This work presents a pulse generator exhibiting excellent performances in the three figures of merit of PGs. Postlayout simulations showed that, for a small area penalty, the robustness of the pulsed-FF is greatly improved.","PeriodicalId":198881,"journal":{"name":"Fifth Asia Symposium on Quality Electronic Design (ASQED 2013)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130458335","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}
