چکیده
We propose a methodology that examines design modules and identifies appropriate vector justification and response propagation requirements for reducing the cost of hierarchical test path construction. Test requirements are defined as a set of fine-grained input and output bit clusters and pertinent symbolic values. They are independent of actual test sets and are adjusted to the inherent module connectivity and regularity. As a result, they combine the generality required for fast hierarchical test path construction with the precision necessary for minimizing the incurred cost, thus fostering cost-effective hierarchical test.

Test Requirement Analysis for Low Cost Hierarchical Test Path Construction
We propose a methodology that examines design modules and identifies appropriate vector justification and response propagation requirements for hierarchical test. Based on a cell-level analysis and transparency composition methodology, test requirements for a module are defined as a set of fine-grained input and output bit clusters and pertinent justification and propagation values. The identif...
متن کاملIntegrated Test Scheduling, Test Parallelization and TAMDesign
We propose a technique integrating test scheduling, scan chain partitioning and test access mechanism (TAM) design minimizing the test time and the TAM routing cost while considering test conflicts and power constraints. Main features of our technique are (1) the flexibility in modelling the systems test behaviour and (2) the support for interconnection test of unwrapped cores and user-defined ...
متن کاملA Flexible Logic BIST Scheme and Its Application to SoC Designs
Built-In Self-Test for logic circuits or logic BIST is gaining popularity as an effective solution for the test cost, test quality, and test reuse problems. Logic BIST implements most of ATE functions on chip so that the test cost can be reduced through less test time, less tester memory requirement, or even a cheaper tester. Logic BIST applies a large number of test patterns so that more defec...
متن کاملHierarchical Test Generation with Built-In Fault Diagnosis
A hierarchical test generation method is presented that uses the inherent hierarchical structure of the circuit under test and takes fault diagnosability into account right from the start. An efficient test compaction method leads to a very compact test set, while retaining a maximum of diagnostic power and a 100% fault coverage for non-fanout circuits. An extension for fanout circuits is also ...
متن کاملRecent Advances in Test Planning for Modular Testing of Core-Based SOCs
Test planning for core-based system-on-a-chip (SOC) designs is necessary to reduce testing time and test cost. In this paper, we survey recent advances in test planning that address the problems of test access and constrained test scheduling for core-based SOCs. We describe several test access architectures proposed by research groups in industry and academia, as well as a wide range of methodo...
