Sharing Logic for Built-In Generation of Functional Broadside Tests

When built-in test generation is used for a design that can be partitioned into logic blocks, it is advantageous to identify groups of blocks whose tests have similar characteristics, and use the same built-in test generation logic for the blocks in each group. This paper studies this issue for a built-in test generation method that […]

Assessing and Comparing Vulnerability Detection Tools for Web Services: Benchmarking Approach and Examples

Selecting a vulnerability detection tool is a key problem that is frequently faced by developers of security-critical web services. Research and practice shows that state-of-the-art tools present low effectiveness both in terms of vulnerability coverage and false positive rates. The main problem is that such tools are typically limited in the detection approaches implemented, and […]

Preemptive Regression Testing of Workflow-based Web Services

    An external web service may evolve without prior notification. In the course of the regression testing of a workflow-based web service, existing test case prioritization techniques may only verify the latest service composition using the not-yet-executed test cases, overlooking high-priority test cases that have already been applied to the service composition before the […]

Reducing the input Test Data Volume under transparent scan

Under an approach to test compaction called transparent scan, a scan circuit is considered as a sequential circuit where the scan-chain inputs and scan-select input are included in the set of inputs of the circuit. This provides the flexibility to interleave functional and scan clock cycles in arbitrary ways, and enhances the ability of transparent-scan […]

Data Center Energy Efficiency:Improving Energy Efficiency in Data Centers Beyond Technology Scaling

  The paper identifies four key themes that should be addressed to improve energy efficiency in data centers: These include understanding the newly emerging workload space to ensure proper matching of architecture design to application requirements; provisioning data center resources for predicted future workloads and applications, and improving the energy proportionality of individual machines to […]

Reducing Masking Effects in CombinatorialInteraction Testing: A Feedback DrivenAdaptive Approach

  The configuration spaces of modern software systems are too large to test exhaustively. Combinatorial interaction testing (CIT) approaches, such as covering arrays, systematically sample the configuration space and test only the selected configurations. The basic justification for CIT approaches is that they can cost-effectively exercise all system behaviors caused by the settings of t […]
