Low-Power Scan Operation in Test Compression Environment

TL;DR: A new on-chip continuous-flow decompressor that integrates seamlessly with test logic synthesis flow, and it fits well into various design paradigms, including modular design flow where blocks come with individual decompressors and compactors.

QC-Fill: Quick-and-Cool X-Filling for Multicasting-Based Scan Test

TL;DR: This paper presents an X-fill scheme that properly utilizes the don't-care bits in test patterns to simultaneously reduce the test time as well as the test power (including both capture power and shifting power).

Trimodal Scan-Based Test Paradigm

TL;DR: The experimental results obtained for large and complex industrial application-specific IC designs illustrate the feasibility of the proposed test scheme despite additional costs and efforts entailed in consolidating architectural changes and operations across a DFT flow.

Capture power reduction using clock gating aware test generation

TL;DR: By taking advantage of the existing clock gating circuitry and selectively holding the value of some scan flip-flops, switching activity during the capture cycles of a test can be reduced.

Embedded deterministic test

TL;DR: This paper presents a novel test-data volume-compression methodology called the embedded deterministic test (EDT), which reduces manufacturing test cost by providing one to two orders of magnitude reduction in scan test data volume and scan test time.

Survey of Test Vector Compression Techniques

TL;DR: This article summarizes and categories hardware-based test vector compression techniques for scan architectures, which fall broadly into three categories: code-based schemes use data compression codes to encode test cubes; linear-decompression- based schemes decompress the data using only linear operations; and broadcast-scan-based scheme rely on broadcasting the same values to multiple scan chains.

Static compaction techniques to control scan vector power dissipation

TL;DR: It is shown here that by carefully selecting the order in which pairs of test cubes are merged during static compaction, both average power and peak power for the final test set can be greatly reduced.

Techniques for minimizing power dissipation in scan and combinational circuits during test application

TL;DR: Heuristics with good performance bounds can be derived for combinational circuits tested using built-in self-test (BIST) and considerable reduction in power dissipation can be obtained using the proposed techniques.
