2019 A new FPGA-based Detection Method for Spurious Variations in PCBA Power Distribution Network
abstract
Nowadays, increasing demand for High-Performance Systems produces significant growth in usage of Field Programmable Gate Arrays (FPGAs) for different applications thanks to their flexibility and high level of parallelism. Such systems rely on complex multi-layer Printed Circuit Board Assemblies (PCBA)with a few dozens of hidden layers, stacked microvias and high-density interconnects. Along with creating new test challenges, the increasing PCBA complexity elevates the criticality of defects in various subsystems. One of such sub-systems is a Power-Delivery-Network (PDN) with operating margin progressively reduced due to increasingly strict requirements of High-Performance applications. As a consequence, Marginal Defects and process variations in a PDN may create latent problems that will manifest in a particular condition thus compromising the overall system performance and causing malfunctions. In this paper we propose a new FPGA-based non-intrusive method to detect Marginal Defects in a PCBA PDN. The method is based on a monitoring circuit that measures signal delays caused by PDN variations and thus detects relevant anomalies. Additional ad-hoc PDN stress circuits have been developed to validate the measurement technique. Experimental results demonstrating the consistency of the proposed approach are obtained by comparing stress and non-stress scenarios.

2019 Post-Silicon Validation of IEEE 1687 Reconfigurable Scan Networks
abstract
The increasing number of embedded instruments used to perform test, monitoring, calibration and debug within a semiconductor device has called for a brand new standard-the IEEE 1687. Such a standard resorts to a reconfigurable scan network to provide efficient and flexible access to instruments and to handle complex structures. As it has to deliver reliable service, many approaches, both formal and simulation-based, have been proposed in the literature to perform test, diagnosis and verification of such networks. This paper focuses on the problem of post-silicon validation of a network, a problem that has not been adequately addressed, yet. We analyze the mismatches between the specification and its silicon implementation, and we propose a methodology to detect a subset of them by applying functional patterns and observing the length of the active scan path. Experimental results on ITC2016 benchmarks demonstrate that the proposed approach is broadly applicable, and able to generate very effective sequences. We also classify mismatches that cannot be targeted relying exclusively on the active scan path length information.

2019 Simulation-based Equivalence Checking between IEEE 1687 ICL and RTL
abstract
A fundamental part of the new IEEE Std 1687 is the Instrument Connectivity Language (ICL), which allows for abstract description of the scan network. The big novelty if compared to legacy solutions like BSDL is the possibility of describing new topology-enabling elements such as the Scan-Muxes in a behavioural way which can be easily and efficiently exploited by Test Generation Tools to retarget instrument-level operations to top-level patterns. This means that for a given design, the Developer will have to write both the RTL and the ICL descriptions: to the author's best knowledge there is no automated tool to make the translation RTL to ICL. This methodology is error-prone due to the human factor, the difference in intent in the two descriptions and the syntactic and semantic complexity of the languages. Incoherence between ICL and RTL will result in retargeting errors, so it is fundamental to validate the equivalence between the two descriptions. This paper presents an automated methodology that starting from the ICL description is able to generate a set of RTL testbenches that can be simulated against the original RTL model to detect discrepancies and incoherence, and provides quantitative metrics in terms of code and functional coverage. Experimental results are reported on the set of ITC2016 set of benchmark networks.

2017 BASTION: Board and SoC test instrumentation for ageing and no failure found
abstract
This is an overview paper that motivates and describes performed work done in the European Commission funded research project BASTION, which focuses on two critical problems of modern electronics: the No-Fault-Found (NFF) and CMOS ageing. New defect classes contributing to NFF have been identified, including timing related faults (TRF) at board level and intermittent resistive faults (IRF) at IC level. BASTION has addressed the mechanisms of ageing and developed several techniques to improve the longevity of electronic products. Embedded Instrumentation, monitors, and IEEE 1687 standard for reconfigurable scan networks (RSN) are seen as an important leverage that helped mitigating the impact of the above listed problems by facilitating a low-latency, scalable online system health monitoring and error localization infrastructure as well as integration of all heterogeneous technologies into a homogeneous demonstration platform. This paper helps the reader to get a general overview of the work performed and provides a collection of references to publications where the respective research results are described in detail.

2017 Marginal PCB assembly defect detection on DDR3/4 memory bus
abstract
A contemporary high-performance system board is a complex 3D object that may contain dozens of hidden layers, stacked microvias, high density interconnect, with all of the above not contributing to the ease of test and reliability. High-speed signals are normally fine-tuned or even calibrated to deliver pitch perfect timing even in the case of now-ubiquitous DDR3 memories. Today, data transmission rates on the board may be reaching multigigabit ranges on a single channel. Such defects like dewetting, cold solder, head-in-pillow, voiding/crack in micro-via or excessive solder voids may result in system performance issues, increased error rates, intermittent faults and other sporadic stability issues observed in certain operation modes, at certain workloads or manifesting in a seemingly stochastic manner. In this work, we present a methodology aiming at systematic discovery of marginal defects, timing related faults and stability issues in board assembly's DDR3/4 data bus as part of the end-of-line testing in volume production environment. The methodology presented in this paper is based on an extended DDR memory controller in which we have converted the bus calibration mechanism into a fine-grain diagnostic instrument, which instead of masking marginal discrepancies (the normal case) would unveil and report them.

2016 On coverage of timing related faults at board level
abstract
In this paper, we demonstrate a clear gap in board level test coverage under category of timing related faults (TRFs). Although there are techniques that are capable to detect TRFs, there is no fault coverage metrics to quantify the quality of these techniques. To do that, we propose an easy-to-implement interconnect-level fault model extension towards TRFs. This extension can be integrated into existing test coverage models providing additional information on coverage of timing-related faults.

2016 Designing reliable cyber-physical systems overview associated to the special session at FDL'16
abstract
CPS, that consist of a cyber part – a computing system – and a physical part – the system in the physical environment – as well as the respective interfaces between those parts, are omnipresent in our daily lives. The application in the physical environment drives the overall requirements that must be respected when designing the computing system. Here, reliability is a core aspect where some of the most pressing design challenges are: monitoring failures throughout the computing system, determining the impact of failures on the application constraints, and ensuring correctness of the computing system with respect to application-driven requirements rooted in the physical environment. This paper provides an overview of techniques discussed in the special session to tackle these challenges throughout the stack of layers of the computing system while tightly coupling the design methodology to the physical requirements.

2016 A suite of IEEE 1687 benchmark networks
abstract
The saturation of the IJTAG concept and its approval as the IEEE 1687 standard in 2014 has generated a wave of research activities and created demand for a set of appropriate and challenging benchmarks. This paper presents such a set developed by an industrial and academic consortium and constructed in a way that facilitates objective comparison of experimental results across research groups as well as represents challenging network examples exhaustively utilizing features and constructs defined by the standard. The suite is arranged in four comprehensive categories, each having its particular purpose and composition principles, as described in the paper. We have also made an analysis of limitations of previous popular and ad-hoc benchmark sets as these limitations majorly motivated our current action. The new public-domain benchmarks are distributed together with source files and documentation through the dedicated web site. Some of the previous research results on IEEE 1687 have been reapplied on the new benchmarks set, thus creating an important initial reference point for the research community.

2015 No Fault Found: The root cause
abstract
No Trouble Found (NTF) has been discussed for several years [1]. An NTF occurs when a device fails at the board/system level and that failure cannot be confirm by the component supplier. There are several explanations for why NTFs occur, including: device complexity; inability to create system level hardware/software transactions which uncover hard to find defects; different environments during testing (power, thermal, noise). More recently a new concept, No Fault Found (NFF), has emerged. A NFF represents a defect which cannot be detected by any known means so far. The premise is that at some point the defect will be exposed - most likely at a customer site when the device is in a system. Given that we looking for a defect that we know nothing about and are theoretically undetectable it will be interesting to see what the panel has to say about the nature of these defects and how we intend to find them.

2014 Design, Verification, and Application of IEEE 1687
abstract
IEEE 1687 (IJTAG) has been developed to enable flexible and automated access to the increasing number of embedded instruments in today's integrated circuits. These instruments enable efficient post-silicon validation, debugging, wafer sort, package test, burn-in, bring-up and manufacturing test of printed circuit board assemblies, power-on self-test, and in-field test. Current paper presents an overview of challenges as well as selected examples in the following topics around IEEE 1687 networks: (1) design to efficiently access the embedded instruments, (2) verification to ensure correctness, and (3) fault management at functions performed in-field through the product's life time.

2012 Re-using chip level DFT at board level
abstract
As chips are getting increasingly complex, there is no surprise to find more and more built-in DFX. This built-in DFT is obviously beneficial for chip/silicon DFX engineers; however, board/system level DFX engineers often have limited access to the build in DFX features. There is currently an increasing demand from board/system level DFX engineers to reuse chip/silicon DFX at board/system level. This special session will discuss: What chip access is needed for board-level for test and diagnosis? How to accomplish the access? Will IEEE P1687 and IEEE 1149.1 solve these problems?

2012 FPGA-based synthetic instrumentation for board test
abstract
This paper studies a new approach for board-level test based on synthesizable embedded instruments implemented on FPGA. This very recent methodology utilizes programmable logic devices (FPGA) that are usually available on modern PCBs to a large extent. The purpose of an embedded instrument is to carry out a vast portion of test application related procedures, perform measurement and configuration of system components thus minimizing the usage of external test equipment. By replacing traditional test and measurement equipment with embedded synthetic instruments it is possible not only to achieve the significant reduction of test costs but also facilitate high-speed and at-speed testing. We detail the motivation and classify the FPGA-based instrumentation into different categories based on the implementation and application domains. Experimental results show the efficiency of this approach.

2011 Automatic SoC Level Test Path Synthesis Based on Partial Functional Models
abstract
While system level test was a topic of extremely high interest during the last decades, the cost of the test program development was continuously growing. The restricted capabilities of Boundary Scan (BS) with respect of such modern challenges as dynamic (timing-accurate), at-speed and high speed testing as well as in-system diagnosis of functional failures create considerable troubles for test engineers in production environments. In this paper, we propose a general modeling methodology for automatic test path synthesis for microprocessor SoC-based systems, that drastically reduces the cost of the test program. The new automation methodology forms a complementary solution to traditional boundary scan by overcoming its weaknesses at no investment into system design process.

2011 SoC and Board Modeling for Processor-Centric Board Testing
abstract
Many contemporary electronic systems are based on System-on-Chips (SoC) such as micro-controllers or signal processors that communicate with many peripheral devices on the system board and beyond. While, SoC test was a topic of extremely high interest during the last decade, the test beyond SoCs didn't get much attention after introduction of Boundary Scan (BS) 30 years ago. It is not a surprise that the restricted capabilities of BS with respect of such modern challenges as dynamic (timing-accurate), at-speed and high-speed testing as well as in-system programming create considerable troubles for test engineers in production environments. In this paper, we point out particular challenges in testing the system's infrastructure beyond the SoCs as well as propose a general modeling methodology for test automation for microprocessor SoC-based system boards. The new so-called "Lego-style" test automation methodology forms a complimentary solution to traditional boundary scan. Together, they provide extended fault coverage that targets shorts, opens, stuck-at faults as well as dynamic faults (e.g. delays and transition faults). The "Legostyle" model allows reducing the labour effort drastically once the library of model components is created.

In this paper, a new very fast fault simulation method to handle the X-fault model is proposed. The method is based on a two-phase procedure. In the first phase, a parallel exact critical path fault tracing is used to determine all the detected stuck-at faults in the circuit, and in the second phase a postprocess is launched which will determine the detectability of X-faults.

2010 Structurally Synthesized Multiple Input BDDs for Speeding Up Logic-Level Simulation of Digital Circuits
abstract
Logic simulation is a critical component of the design tool flow in modern hardware development efforts. In this paper a new algorithm for parallel logic simulation is proposed based on a new model of Structurally Synthesized Multiple Input BDDs (SSMIBDD). The SSMIBDDs allow further model size reduction and therefore higher speed of logic simulation than its predecessor SSBDD model. The paper presents a method of SSMIBDD synthesis from the given gate network and the main principles of parallel logic simulation with SSMIBDDs. Experimental data demonstrate in average 2.9 times improvement in the speed of logic simulation because of the reduced number of nodes in SSMIBDDs. Similarly to the SSBDDs, the new model preserves structural information about the circuit, which is needed for processing of faults. The reduced complexity of SSMIBDDs leads to the more powerful fault collapsing and as the result to more efficient fault simulation and fault injection to evaluate the dependability of fault tolerant circuits.

2010 Fault collapsing with linear complexity in digital circuits
abstract
The paper presents a new structural fault-independent fault collapsing method for test generation based on the topology analysis of the circuit, which has linear complexity. Fault collapsing is carried out by superposition of binary decision diagrams (BDD) for logic gates, which is used for constructing structurally synthesized BDDs (SSBDD). A new class of SSBDDs with multiple inputs (SSMIBDD) is proposed to reduce the size of collapsed fault sets. Experimental data show that the fault collapsing by the proposed method is more efficient than other strucural fault collapsing methods with comparative time cost are.

2009 Fast extended test access via JTAG and FPGAs
abstract
This paper describes a new test access protocol for system-level testing of printed circuit boards for manufacturing defects. We show that the protocol can be based on standard boundary scan (BS) instructions and test access mechanism (TAM). It means that the methodology does not require any changes/redesign of hardware and can be immediately implemented in the electronic manufacturing. Our solution needs however a proper software support and availability of programmable devices (FPGAs, CPLDs, etc.) on the board under test. The new technique dramatically extends the applicability of BS testing in the reality of modern complex on-board data transfer buses and protocols. Potentially, it can also increase the speed of in-system programming of flash memories and other tasks that are traditionally performed using BS.

2008 Parallel fault backtracing for calculation of fault coverage
abstract
A new improved method for calculation of fault coverage with parallel fault backtracing in combinational circuits is proposed. The method is based on structurally synthesized BDDs (SSBDD) which represent gate-level circuits at higher, macro level where macros represent subnetworks of gates. A topological analysis is carried out to generate an efficient optimized model for backtracing of faults to minimize the repeated calculations because of the reconvergent fanouts. The algorithm is equivalent to exact critical path tracing, however, processing the backtrace in parallel for a group of test patterns. Because of the parallelism, higher abstraction level modeling, and optimization of the topological model, the speed of fault simulation was considerably increased. Compared to the state-of-the-art commercial fault simulators the gain in speed was several times.

2007 Ultra Fast Parallel Fault Analysis on Structurally Synthesized BDDs
abstract
An efficient method of parallel fault simulation for combinational circuits is proposed. The method is based on structurally synthesized BDDs (SSBDD) which represent gate-level circuits at higher, macro level where macros represent subnetworks of gates. Converting gate-level circuits to the macro-level is accompanied with fault collapsing. A parallel fault analysis algorithm for SSBDDs was developed. For the faults at fanout stems a new full Boolean differential based parallel fault analysis method is proposed. The algorithm is equivalent to exact critical path tracing. Because of the parallelism and higher abstraction level modeling the speed of analysis is considerably increased. Experimental data show that by the new method speed-up measured in several times has been achieved compared to the current state-of-the-art commercial tools and other exact critical path tracing methods.

2006 Off-Line Testing of Delay Faults in NoC Interconnects
abstract
Testing of high density SoCs operating at high clock speeds is an important but difficult problem. Many faults, like delay faults, in such sub-micron chips may only appear when the chip works at normal operating speed. In this paper, we propose a methodology for at-speed testing of delay faults in links connecting two distinct clock domains in a SoC. We give an analytical analysis about the efficiency of this method. We also propose a simple digital hardware structure for the receiver end of the link under test to detect delay faults. It is possible to extend our method to combine it with functional testing of the link and adapt it for online testing

2005 An Educational Environment for Digital Testing: Hardware, Tools, and Web-Based Runtime Platform
abstract
We describe a new e-learning environment and a runtime platform for educational tools on digital system testing and design for testability. This environment is being developed in Tallinn University of Technology and consists of several functional layers. The first one is the hardware component used for illustration of various physical phenomena appearing in defected circuits. In many cases such phenomena are hard to illustrate by software simulation or by any other means, which makes the usage of such a hardware component unavoidable. The second component is a set of university tools covering a large scope of topics in basics of testing, diagnosis, and BIST. The tools represent an efficient alternative to hard-to-learn and expensive commercial CAD systems. The wrapper to these two components is a cross-platform Web interface that represents a server-based solution for using all the available tools and the hardware over Internet. The whole platform is an extendable server-based low-cost solution, which is easy to set-up and use. The learning environment is complemented by laboratory work scenarios and teaching materials that also available in the Web.

This article describes a novel approach to fault diagnosis suitable for at-speed testing of board-level interconnect faults.This approach is based on a new parallel test pattern generator and a specifically fault detecting sequence. The test sequence has tree major advantages.At first, it detects both static and dynamic faults upon interconnects. Secondly, it allows precise on-chp at-speed fault diagnosis of interconnect faults.Third, the hardware implementation of both the test generator and the response analyzer is very efficient in terms of silicon area.

2001 Timing simulation of digital circuits with binary decision diagrams
abstract
Meeting timing requirements is an important constraint imposed on highly integrated circuits, and the verification of timing of a circuit before manufacturing is one of the critical tasks to be solved by CAD tools. In this paper, a new approach and the implementation of several algorithms to speed up gate-level timing simulation are proposed where, instead of gate delays, path delays for tree-like subcircuits (macros) are used. Therefore timing waveforms are calculated not for all internal nodes of the gate-level circuit but only for outputs of macros. The macros are represented by structurally synthesized binary decision diagrams (SSBDD) which enable a fast computation of delays for macros. The new approach to speed up the timing simulation is supported by encouraging experimental results.
