Being the heart of ANN, the performance of artificial neuron directly determines the performance of the entire system. Artificial neuron’s algorithm comprises of two portions, sum-of-product for input connection and activation function. Due to looped calculation required for sum-of-product and non-linearity calculation of activation function, implementing an artificial natively will yield a very low efficiency performance. This paper presents an under-going work that illustrate the use of several technique, such as pipelining and hierarchical distributed adder, to achieve high performance artificial neuron. Our measured result shows that it takes about 528 clock cycles for the artificial neuron to complete processing for 8 input connections. The performance is estimated to increase by 82 % with proposed technique.","PeriodicalId":220508,"journal":{"name":"2020 IEEE 29th Asian Test Symposium (ATS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791099","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 MRL AND and OR gates are implemented by the RRAM devices, and the MRL NOT gate is implemented by the CMOS inverter. However, the MRL circuits are prone to test escape. This work proposes a method to improve the testability of MRL circuits by replacing the CMOS inverters with the FinFET inverters. The test escape problem is solved by adjusting the switching threshold voltages of the FinFET inverters, and it is implemented by selecting the FinFET inverters in different operation modes. In Addition, some equivalent relationships in the fault set of the improved MRL gates are discovered. These fault equivalences of MRL gates result in a fault collapse ratio of about 50%. The test patterns for the production test of the improved MRL circuits can be generated by the traditional ATPG method. The test results of some typical MRL circuits obtained from the commercial ATPG tool show that the proposed method is able to achieve 100% fault coverage and at least 55% fault collapse ratio.","PeriodicalId":220508,"journal":{"name":"2020 IEEE 29th Asian Test Symposium (ATS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133952293","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}

When testing the frequency characteristics of analog/mixed-signal ICs, a multi-tone (sum of multiple sine waves) signal is often used instead of a single tone signal, to reduce their testing time. However, as the amplitude of each tone signal becomes smaller if multiple sine waves are simply added without care of their initial phases, the SNR of the test result becomes worse and the test accuracy becomes lower. To alleviate this problem, it is necessary to generate a multi-tone signal using a crest factor reduction algorithm. There are four representative multi-tone signal generation algorithms for reducing crest factor, and their study results are presented.","PeriodicalId":220508,"journal":{"name":"2020 IEEE 29th Asian Test Symposium (ATS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124459147","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 order to keep up with continuously shrinking technology nodes, compression along with compaction techniques became a standard methodology allowing to control the cost of test. Typically compaction techniques focus on detectability thus maintaining high quality of test, but neglect or, in many cases, ignore their impact on diagnosis. This paper presents a compactor which allows significantly improving chain diagnosis resolution while maintaining high quality standards from detectability point of view and having virtually no impact on test time and logic diagnosis. The paper presents the X-press compactor which is driven in a way allowing to maximize diagnostic ability of chain failures. Specifically, the number of physical failure analysis-ready cases increased up to two times. The feasibility and efficiency of the proposed solution is confirmed by a number of experimental results performed for industrial designs, including actual chain diagnosis.","PeriodicalId":220508,"journal":{"name":"2020 IEEE 29th Asian Test Symposium (ATS)","volume":"264 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115979107","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}

To achieve secure device identification, a large number of CRPs are collected by the manufacturers, thereby increasing the measurement costs. This paper proposes a novel scheme, which employs a logic built-in self-test (LBIST) circuit, to efficiently collect the CRPs during production tests. As a result, no additional measurement is required for the CRP collection. In addition, the proposed technique can counter machine-learning (ML) attacks because of the complicated relationship between challenge and response through the LBIST circuit. Through the proof-of-concept implementation, in which a field-programmable gate array (FPGA) is used, we demonstrate the PUF performance can be evaluated by a test pattern generated by the LBIST circuit. Furthermore, the vulnerability due to ML attacks using a support vector machine (SVM) and random forest (RF) is lowered by more than two times compared to the naive usage of PUF.","PeriodicalId":220508,"journal":{"name":"2020 IEEE 29th Asian Test Symposium (ATS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114907440","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, inaccuracies present in the data from these EIs, due to their selfaging and resolution limitations during digitization, can lead to an inaccurate EOL assessment. In this paper, it is presented that in the presence of such inaccuracies from EIs as well as correlation between EIs, principal component analysis (PCA) based datafusion approach for determining the EOL of selected critical paths provided overall better EOL predictions as compared to EOL predictions based on standalone EIs. Verification was performed with a commercial software-based EOL predictor tool ARULE running on a personal computer. Moreover, the presented results on the computational requirements for the presented data-fusion approach showed little overhead in terms of memory, execution time and energy requirements.","PeriodicalId":220508,"journal":{"name":"2020 IEEE 29th Asian Test Symposium (ATS)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122971740","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}
