October 4, 2015 (Sunday) Tutorial 1: by Steve SUNTER We analyze recent trends in IC processes and design, and implications for test, then look at trends in testing. Next, we discuss trends in ad hoc DFT and fault simulation, then all relevant IEEE DFT standards: 1149.1, .4, .6, .7, .8, P1149.10, and 1687. The trend analysis concludes with a review of BIST techniques. Addressed circuits include PLL/DLL, ADC/DAC, SerDes/DDR, general I/Os, and last but not least, random analog. Next, seven essential principles of practical analog BIST are presented. Lastly, we discuss practical DFT techniques, ranging from analog defect simulation and the classic analog bus, to oversampling and undersampling methods that greatly improve range, resolution, and reusability.
by Domenic FORTE, Mohammad TEHRANIPOOR The migration from a vertical to horizontal
business model has made it easier to introduce many
vulnerabilities to electronic component design and
supply chain. In the first part of this tutorial, we
discuss the major issues that must be addressed
including securing hardware, verifying trustworthiness
of integrated circuits, unique key generation,
side-channel attacks and more. . In the latter two
parts of this tutorial, we will place more emphasis on
detection and prevention of hardware Trojans and
counterfeit electronic parts and discuss how test can
help. In this tutorial, we will cover (i) An
introduction to hardware security and trust
(physically unclonable functions, true random number
generation, hardware Trojans, counterfeit ICs,
side-channel attacks, supply chain vulnerabilities,
etc.), (ii) Background and motivation for hardware
Trojan and counterfeit prevention/detection; (iii)
Taxonomies related to both topics; (iv) Existing
solutions; (v) Open test challenges; (vi) Design for
security and trust, (vii) New and unified solutions to
address these challenges.
Tutorial 3: BEYOND DFT: THE CONVERGENCE OF DFM, VARIABILITY, YIELD, TEST, DIAGNOSIS AND RELIABILITY by Srikanth VENKATARAMAN, Robert AITKEN
The tutorial goal is to show how design for yield
(DFY) and design for manufacturability (DFM) are
tightly coupled into what we conventionally think of
as test. As process geometries shrink, the line
between defects and process variation blurs to the
point where it is essentially non-existent. As feature
sizes reduced, systematic mechanism-limited yield loss
began to appear as a substantial component in yield
loss due to the interaction between design and
manufacturing. The basics of yield and what fabs do to
improve defectivity and manage yield are described.
DFM techniques to analyze the design content, flag
areas of design that could limit yield, and make
changes to improve yield are discussed. In DFM/DFY
circles, it is common to speak of defect limited
yield, but it is less common to think of test-limited
yield, yet this concept is common in DFT (e.g. IDDQ
testing, delay testing). Test techniques to close the
loop by crafting test patterns to expose the defect
prone feature and circuit marginality through ATPG,
and by analyzing silicon failures through diagnosis to
determine the features that are actually causing yield
loss and their relative impact are covered.
Afternoon Tutorial 4:
PRACTICES IN HIGH SPEED I/O TESTING by Salem ABDENNADHER, Saghir SHAIKH
This tutorial presents the existing industrial
techniques to meet the ever increasing test complexity
of High Speed IO's (HSIO). It first describes the
basic design of both serial and parallel HSIOs and
then presents various testing methods of HSIO, such as
timing margining, voltage margining, compensation
testing, leakage testing and etc. The examples of all
these test methods will be presented with special
emphasis on DFT and BIST based approaches of HSIO
testing and their suitability to the production level
environment.
Tutorial 5:
TESTING OF TSV-BASED 2.5D- AND 3D-STACKED ICS by Erik Jan MARINISSEN
Stacked ICs with vertical interconnect containing
fine-pitch micro-bumps and through-silicon vias (TSVs)
are a hot-topic in design and manufacturing
communities. These 2.5D- and 3D-SICs hold the promise
of heterogeneous integration, inter-die connections
with increased performance at lower power dissipation,
and increased yield and hence decreased product cost.
However, testing for manufacturing defects remains an
obstacle and potential showstopper before 3D-SICs can
become a reality. There are concerns about the cost
or, even worse, feasibility of testing such TSV-based
3D chips. In this tutorial, we present key concepts in
3D technology, terminology, and benefits. We discuss
design and test challenges and emerging solutions for
2.5D- and 3D-SICs. Topics to be covered include an
overview of 3D integration and trend-setting products
such as a 2.5D-FPGA and 3D-stacked memory chips, test
flows and test content for 3D chips, advances in wafer
probing, 3D design-for-test architectures and ongoing
IEEE P1838 standardization efforts for test access,
and 3D test cost modeling and test-flow selection.
Tutorial 6:
DELAY TEST: CONCEPTS, THEORY AND RECENT TRENDS by Suriyaprakash NATARAJAN, Arani SINHA
This tutorial covers fundamental concepts,
recent ideas and industry practices on validating
and testing integrated circuits for speed failures.
Main areas covered are: (a) defects and
marginalities such as crosstalk, voltage droop,
multiple-input switching and charge-sharing that
result in speed failures, (b) delay fault models and
fault sensitization conditions, (c) classical and
advanced metrics to measure delay test quality and
methods to improve them, (d) design-for-test to
facilitate application of delay tests, (e)
algorithms for test generation, fault simulation and
diagnosis, including cell-aware and those targeting
memory shadow and time borrowing logic, and (g)
applications in post-silicon validation, speed
binning and in-field reliability using industry case
studies.

Morning Tutorial 7:
HIERARCHICAL TEST FOR TODAY’s SoC and IoT by Yervant ZORIAN
Today’s SoC and IoT design teams, use
heterogeneous IP blocks from numerous sources, and
multi-level hierarchical architecture (IPs, cores,
subchips, chip). To test such SOCs and IoTs, DFT
designers adopt new hierarchical test solutions
across heterogeneous cores (memories, logic, AMS
and interface IP), in order to support concurrent
test, power reductions during test, DFT closure,
isolated debug and diagnosis, pattern porting,
calibration, and uniform access. This tutorial
covers hierarchical test trends and solutions
based on IEEE test standards, such as IEEE 1500,
1687 and 1149.1, along with intelligent
infrastructure IP to help achieve the above
advantages.
Tutorial 8:
TEST, DIAGNOSIS, AND ROOT-CAUSE IDENTIFICATION OF FAILURES FOR BOARDS AND SYSTEMS by Krishnendu CHAKRABARTY, William EKLOW, Zoe
CONROY
The gap between working silicon and a working
board/system is becoming more significant and
problematic as technology scales and complexity
grows. The result of this increasing gap is failures
at the board and system level that cannot be
duplicated at the component level. These failures
are most often referred to as "NTFs" (No Trouble
Founds). The result of these NTFs can range from
higher manufacturing costs and inventories to
failure to get the product out of the door. The
problem will only get worse as technology scales and
will be compounded as new packaging techniques (SiP,
SoC, 3D) extend and expand Moore's law. This is a
problem that must be solved, yet, little effort has
been applied up to this point. This tutorial will
provide a detailed background on the nature of this
problem and will provide DFT, test, and root-cause
identification solutions at the board/system level.
Practical insights from industry case studies will
be highlighted and the presenters will show how
recent research results from academia can help solve
problems being faced by industry.
Tutorial 9:
STATISTICAL ADAPTIVE TEST METHODS TARGETING "ZERO DEFECT" IC QUALITY AND RELIABILITY by Adit SINGH
Commercial applications continue to demand ever
higher IC quality, most notably a "zero defect"
target from automotive manufacturers. To cost
effectively meet this challenge, innovative new
statistical screening techniques improve test
effectiveness by first identifying "suspect" parts,
that are then more extensively tested, sometimes
using tests that specifically target the suspected
failure modes. Such adaptive tests exploit
statistical correlations in process, performance and
defect parameters. This tutorial presents a range of
such test methodologies, and illustrates their
effectiveness with results from recently published
studies on production parts. Commercial tools from
new companies in the "Adaptive Test" space are also
discussed.
Afternoon Tutorial 10:
MEMORY TEST & REPAIR IN NANOMETER ERA by Manuel D'Abreu, Yervant ZORIAN
Recent growth in content creation has led to an
explosion in the use of embedded memories. This
tutorial will present a range of memories used,
including RAMs and Non-Volatile memories (Flash) and
how to ensure detection of today's defects upon
manufacturing and during life time, including
process variation and FinFET specific defects. BIST
and Repair solutions to address yield optimization,
endurance and data retention of failure modes will
be presented. Given the tens of thousands of
embedded memory instances in today's SOCs, the
tutorial will also cover power management
constraints, functional timing implications, test
scheduling optimization, and area minimization
options.
Tutorial 11:
COMBINING STRUCTURAL AND FUNCTIONAL TEST APPROACHES ACROSS SYSTEM LEVELS by Artur JUTMAN, Hans-Joachim WUNDERLICH, Matteo
SONZA REORDA
This tutorial introduces into the best
practices, current challenges and advanced
techniques of high quality system-level test and
diagnosis. Specialized techniques and industrial
standards of testing complex systems (which may
correspond to a System on Chip, board or
interconnected system) are introduced. The reuse for
system test of design for test structures and test
data developed at module level is discussed,
including the limitations and research challenges.
Structural test methods have to be complemented by
functional test methods; hence, state-of-the-art and
leading edge research for functional testing are
covered. Solutions change depending on the scenario
(manufacturing test or in field test) and the goal
(test or diagnosis). The tutorial also discusses the
role of standards and regulations in the area. Test
cases are described and discussed.
Tutorial 12:
FROM DATA TO ACTIONS: APPLICATIONS OF DATA ANALYTICS IN SEMICONDUCTOR MANUFACTURING & TEST by Haralampos STRATIGOPOULOS, Yiorgos MAKRIS
This tutorial seeks to elucidate the utility of
data analytics in semiconductor manufacturing and
test. Relevant concepts from data analytics theory
will be introduced and agglomerated with current
practice, showcasing their effectiveness on actual
case studies with industrial data. A comprehensive
survey of the relevant literature (including but not
limited to the presenters' own work) will be
provided, organized around four themes: (i) Test
cost reduction through replacement of expensive
tests by inexpensive alternatives and/or elimination
of superfluous tests, either statically or
adaptively during test application, (ii)
Pre-deployment evaluation of candidate test methods
through probabilistic test metrics, (iii)
Post-production performance calibration through
cost-effective knob tuning, and (iv) Yield learning
and process monitoring through analysis of process
variation impact on wafer-level spatial correlation.
