Abstract [en]

As fault handling in multi-processor system-on-chips (MPSoCs) is a major challenge, we have developed an MPSoC demonstrator that enables experimentation on fault injection and fault handling. Our MPSoC demonstrator consists of (1) an MPSoC model with a set of components (devices) each equipped with fault detection features, so called instruments, (2) an Instrument Access Infrastructure (IAI) based on IEEE P1687 that connects the instruments, (3) a Fault Indication and Propagation Infrastructure (FIPI) that propagates fault indications to system-level, (4) a Resource Manager (RM) to schedule jobs based on fault statuses, (5) an Instrument Manager (IM) connecting the IAI and the RM, and (6) a Fault Injection Manager (FIM) that inserts faults. The main goal of the demonstrator is to enable experimentation on different fault handling solutions. The novelty in this particular demonstrator is that it uses the existing test features, i.e. IEEE P1687 infrastructure, to assist fault handling. The demonstrator is implemented and a case study is performed.

Abstract [en]

This paper discusses the reuse and retargeting of test instruments and test patterns using the IEEE P1687 standard in an era where reuse of existing functional elements and integration of IP blocks is accelerating rapidly. It briefly discusses the deficiencies of existing 1149.1 (JTAG) and 1500 standards and demonstrates how the new standard, P1687, plugs these exposures by specifying JTAG as an off-chip to on-chip interface to the instrument access infrastructure. It provides a simple example to underscore the need for the standard and then builds on this example to show how the standard can be used for more complex situations.

Abstract [en]

This paper addresses Test Application Time (TAT) reduction under power constraints for core-based 3D Stacked ICs (SICs) connected by Through Silicon Vias (TSVs). Unlike non-stacked chips, where the test flow is well defined by applying the same test schedule both at wafer sort and at package test, the test flow for 3D TSV-SICs is yet undefined. In this paper we present a cost model to find the optimal test flow. For the optimal test flow, we propose test scheduling algorithms that take the particulars of 3D TSV-SICs into account. A key challenge in testing 3D TSV-SICs is to reduce the TAT by co-optimizing the wafer sort and the package test while meeting power constraints. We consider a system of chips with cores that are accessed through an on-chip JTAG infrastructure and propose a test scheduling approach to reduce TAT while considering resource conflicts and meeting the power constraints. Depending on the test schedule, the JTAG interconnect lines that are required can be shared to test several cores. This is taken into account in experiments with an implementation of the proposed scheduling approach. The results show significant savings in TAT.

Abstract [en]

Test planning for core-based 3D stacked ICs under power constraint is different from test planning for non-stacked ICs as the same test schedule cannot be applied both at wafer sort and package test. In this paper, we assume a test flow where each chip is tested individually at wafer sort and jointly at package test. We define cost functions and test planning optimization algorithms for non-stacked ICs, 3D SICs with two chips and 3D SICs with an arbitrary number of chips. We motivate the problem by demostrating the trade-off between test time and hardware, within a power constraint, while arriving at the minimal cost.

Abstract [en]

Modern chips may contain a large number of embedded test, debug, configuration, and monitoring features, called instruments. An instrument and its instrument data, instrument access procedures, may be pre-developed and reused and instruments may be accessed in different ways through the life-time of the chip, which requires retargeting. To address instruments reuse and retargeting, IEEE P1678 specifies a hardware architecture, a hardware description language, and an access procedure description language. In this paper, we investigate how P1687 facilitates instrument access procedure reuse and retargeting.

Abstract [en]

The IEEE P1687 (IJTAG) standard proposal aimsat standardizing the access to embedded test and debug logic(instruments) via the JTAG TAP. P1687 specifies a componentcalled Segment Insertion Bit (SIB) which makes it possible toconstruct a multitude of alternative P1687 instrument accessnetworks for a given set of instruments. Finding the best accessnetwork with respect to instrument access time and the numberof SIBs is a time-consuming task in the absence of EDA support.This paper is the first to describe a P1687 design automationtool which constructs and optimizes P1687 networks. Our EDAtool, called PACT, considers the concurrent and sequential accessschedule types, and is demonstrated in experiments on industrialSOCs, reporting total access time and average access time.

Abstract [en]

Increasing soft error rates for semiconductor devices manufactured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For non-real-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number of checkpoints such that the average execution time is minimal. While minimal average execution time is important, it is for real-time systems important to provide a high probability that deadlines are met. Hence, there is a need of probabilistic guarantees that jobs employing RRC complete before a given deadline. First, we present a mathematical framework for the evaluation of level of confidence, the probability that a given deadline is met, when RRC is employed. Second, we present an optimization method for RRC that finds the number of checkpoints that results in the minimal completion time while the minimal completion time satisfies a given level of confidence requirement. Third, we use the proposed framework to evaluate probabilistic guarantees for RRC optimization in non-real-time systems.
