For certain serial interface protocols (like the ubiquitous Universal Serial Bus (USB)) and some legacy input/output interfaces, high voltages like 1.8V, 3.3V and even 5.0V are still being used for protocol compliance. It is costly in silicon fabrication to provide transistors with different gate-oxide thickness to cater for various high voltage and speed requirements. In order to minimize the type of gate oxide thickness in advanced silicon process, circuit innovation is usually required to enable transistor to operate with voltage higher than its reliability limit, yet protected from electrical overstress (EOS). This paper discusses a new circuit architecture that is able to detect voltage source as well as to switch between external source and internal biasing voltage to ensure all transistors operating with high voltage are not exposed to the voltage limit. This circuit is low power in nature since it does not consume static current. By having this protection scheme, this would enable the use of transistor to support high-voltage application without incurring cost of having additional thicker gate-oxide transistor. In terms of application, this architecture can be used in integrated chip design involving various high-voltage supplies.","PeriodicalId":198881,"journal":{"name":"Fifth Asia Symposium on Quality Electronic Design (ASQED 2013)","volume":"43 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":"131668752","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}

Further, in very deep sub-micron technologies, temperature has a crucial role in both performance and power. The proposed framework presents a novel layered synthesis optimization coupled with temperature aware supply and body bias voltage scaling to operate the design at various “tunable” error tolerant modes.

Conventional PUF circuitry suffers from a reliability problem in which a consistent output value is not guaranteed because of environmental changes such as the power supply voltage and operating temperature. This paper introduces a PUF circuit that yields consistent responses that overcome fluctuations in the operating conditions. The proposed PUF is based on the variation in the crosstalk between adjacent transmission lines, which reflects the random physical structure of interconnected lines. The proposed PUF cell comprises three transmission lines and a sense amplifier. The sense amplifier catches the crosstalk differences between two adjacent transmission lines. The crosstalk differences reflect a physical structure variation, which is immune to changes in the operating environment. The proposed PUF circuit yields a well-balanced distribution probability, (100/2n)%, for each challenge bit with σ = 1%. The identification generated by the PUF can be regarded as core functionality for authentication and encryption in security applications.","PeriodicalId":198881,"journal":{"name":"Fifth Asia Symposium on Quality Electronic Design (ASQED 2013)","volume":"263 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":"123100786","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}

Coverage directed test generation (CDTG) techniques analyze coverage results and adapt the input stimuli (for verification) generation process to improve the coverage. One of the important components of CDTG technique is the constraint solver. The CDTG constraint solvers require large amount of memory and time to generate solution. To overcome these limitations we propose a methodology based on consistency algorithm to attain faster coverage. In order to demonstrate the practical effectiveness of the methodology, we used it to test some benchmark constraint satisfaction problems (CSPs) and Xbar switch. The results show an increase in coverage along with a reduction in time required to generate the test cases.","PeriodicalId":198881,"journal":{"name":"Fifth Asia Symposium on Quality Electronic Design (ASQED 2013)","volume":"38 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":"114199581","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}

From the thermal transient analysis of a 3W warm white LED, it was observed that the Al filled composite exhibits the lowest junction temperature of 38.3 °C compared to the other two fillers.

This paper presents a methodology for modeling debugging changes in terms of standalone assertion statements and evaluating their effect by running emulation without requiring any design modification or recompilation step, during emulation based debug. The set of assertions representing debugging changes are transformed into a set of constraints that are directly programmed into the emulator and an associated logic analyzer. When emulation is resumed from a bug-free state, these constraints are enforced by automatically forcing necessary signals to desired values, according to the specified assertions. Multiple debugging changes can thus be verified before eventually porting the fixes to design RTL followed by recompilation and emulation rerun. The proposed methodology also facilitates block based SoC development, by allowing a designer to enforce the correct functional behavior of some other block whose output affects the behavior of the block he is working on. Application of the proposed debugging system to debugging of real industry standard designs has been seen to reduce debugging turn-around time significantly.","PeriodicalId":198881,"journal":{"name":"Fifth Asia Symposium on Quality Electronic Design (ASQED 2013)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124871152","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}
