Prior work proposed the Carnegie-Mellon logic characterization vehicle (CM-LCV) as an improved test chip for yield learning. The highly regular nature of the CM-LCV test chip is particularly appealing for BIST; the current work describes a BIST scheme that achieves 100% input-pattern fault coverage with an 86.9% reduction in test time for a reference design. Furthermore, all of these properties are achieved with a minimal hardware overhead.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127225312","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, for circuits with narrow paths or random-resistant corner cases, purely random techniques can fail to produce adequate results. Deterministic techniques can aid this process; however, they add significant computational complexity. This paper presents a Register Transfer Level (RTL) abstraction technique to derive relationships between inputs and path activations. The abstractions are built off of various program slices. Using such a variety of abstracted RTL models, we attempt to find patterns in the reduced state and input with their resulting branch activations. These relationships are then applied to guide stimuli generation in the concrete model. Experimental results show that this method allows for fast convergence on hard-to-reach states and achieves a performance increase of up to 9× together with a reduction of test lengths compared to previous hybrid search techniques.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129273639","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}

Incorrect outputs of digital chips are forced by applying scan patterns under non-destructive stress conditions. From binary mismatch responses collected in continue-on-fail mode, numeric data features are formed by grouping and counting mismatches in each group, thus defining a chip's “analog” failure signature. We use machine learning to explore prediction models of system-level test (SLT) failures by comparing signatures of chip samples from known SLT pass/fail bins. Important features that clearly separate the SLT pass/fail chips are identified.

The fault coverage of this costly optical test is not sufficient given the quality requirements. Studies on devices produced at large volume have shown that Horizontal Fixed Pattern Noise (HFPN) is one of the common image failures encountered on products that present fault coverage problems, and this is the main cause of customer returns for many products. A detailed analysis of failed devices has demonstrated that HFPN failures arise from changes of electronic circuit topology in pixel addressing decoders or the metal lines required for pixel powering and control. These changes are usually due to the presence of spot defects, causing some pixels in a row to operate incorrectly, leading to an HFPN failure. Moreover, defects resulting in partially degraded metal lines may not induce image failure in limited industrial test conditions, passing the optical tests. Later, these defects may produce an image failure in the field, either because the capture conditions would be more stringent, or because the defects would evolve into catastrophic faults due to electromigration. In this paper, we have first enhanced the HFPN detection algorithm in order to improve the fault coverage of the optical test. Next, a built-in self-test structure is presented for the on-chip detection of catastrophic and non-catastrophic defects in the pixel power and control lines.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121521352","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}

One of the motivations for this type change is to learn important information (such as encryption keys, spreading codes) from the hardware and pass this information to a malicious party through wireless means. In order to evade detection, such unauthorized communication can be hidden within legitimate bursts of transmit signal. In this paper, we present a stealth circuit for unauthorized transmissions which can be hidden within the legitimate signal. A CDMA-based spread spectrum with a CDMA encoder is implemented with a handful of transistors. We show that the unauthorized signal does not alter the circuit performance while being easily detectable by the malicious receiver.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114694051","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}

Traditional jitter measurement method relies on precise and expensive instrumentations. This paper proposes a low cost jitter measurement and separation method. Instead of using traditional time internal analysis equipment, a simple Analog-to-Digital Converter (ADC) is used as the jitter measurement device. The clock under test is applied as the sampling clock of an ADC while the ADC is sampling a full scale sine wave. The ADC output contains the information of the clock jitter. The algorithm will separately detect the effects of Periodic Jitter, Dual-Dirac Jitter and Random Jitter, and accurately compute the rms value of each jitter component. This method offers great potential for wide use in low cost applications and especially in on-chip or on-board jitter measurement applications. Simulation results demonstrate the functionality, accuracy and robustness of the proposed low-cost jitter measurement method.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128688475","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 test vector omission procedure requires fault simulation for every test vector (or subsequence) that it considers for omission. It was noted earlier that it is possible to reduce the set of simulated faults based on the clock cycles where the faults are detected. However, this reduction is effective only for the later test vectors of a sequence. This paper defines a minimal set of faults that need to be simulated for the omission of a test vector by considering, in addition to detection clock cycles, also clock cycles where test subsequences start. The former are computed by a conventional sequential fault simulation process. For the latter, the paper introduces a sequential reverse order fault simulation process, and an approximation with a reduced computational complexity. Experimental results show significant reductions in the run time for test vector omission without affecting the level of compaction.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130726132","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 present the first approach for the automated diagnosis of flow-based microfluidic biochips.

This paper describes an improved test cube merging procedure for four-way bridging faults. The procedure is motivated by the prevalence of bridging defects and the fact that test sets for bridging faults are larger than test sets for single stuck-at faults. A four-way bridging fault g<sub>i</sub>/a<sub>i</sub>/h<sub>i</sub> models the case where a value a<sub>i</sub> of a line h<sub>i</sub> dominates the value of a line g<sub>i</sub>. A basic test cube merging procedure considers a set of test cubes C<sub>det</sub> that detects target faults. The paper extends the set of test cubes to include, in addition to C<sub>det</sub>, a set of test cubes C<sub>dom</sub> that assign values to dominating lines. Test cubes from C<sub>dom</sub> have significantly fewer specified values than test cubes from C<sub>det</sub>. When test cubes from C<sub>dom</sub> are merged with test cubes from C<sub>det</sub>, each resulting test cube detects more faults, and fewer test cubes are needed for detecting the same set of target faults.","PeriodicalId":187545,"journal":{"name":"2015 IEEE 33rd VLSI Test Symposium (VTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125381064","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}
