IDEAS01: Refactoring to Requirements Documents: An approach Aspect Oriented

Typical problems of a requirements document, regarding its contents and organization, involve deficient modularization where requirements artifacts may deal with too much information, duplication of requirements, scattering requirements, tangled problems, among other problems. In this paper we describe how to improve requirements documents by removing duplication of information using aspect-oriented refactoring.     

IDEAS09: Applying a Security Domain Requirements Engineering Process for Software Product Lines

Security requirements management is especially important in software product lines, given that a weakness in security or a security breach can cause problems throughout all the products of a product line. The main contribution of this work is that of illustrating, by describing part of a real case study, a guided, systematic and intuitive way of dealing with security requirements from the early stages of the product line lifecycle by applying our proposed process of security requirements engineering for software product lines (SREPPLine), which makes it easier the variability and reusability management as well as the traceability relations of the security requirements in the product line. It is based on the use of the latest security requirements techniques, together with the integration of the Common Criteria (ISO/IEC 15408) and ISO/IEC 27001 controls, so that it facilitates the conformance of the product line and its products to the most relevant security standards with regard to the management of security requirements, such as ISO/IEC 27001 and ISO/IEC 15408.

Tester Memory Requirements and Test Application Time Reduction for Delay Faults with Digital Captureless Test Sensors

In this paper, we present a technique called Digital Captureless Delay Testing Sensors (DCDTS). This technique allows the detection of delay faults left uncovered by launch-on-capture transitions due to excessive resources (mainly test time or tester memory) requirements, with top-off random launch-on-shift patterns that do not require fast switching scan enable signals. The DCDTS random patterns are internally generated, requiring virtually no additional test application time or tester memory. As such, DCDTS can be seen as a new way to save both test time and tester memory. Results show that DCDTS can achieve pattern volume and test time reduction factors of up to 3. When used in complement to existing compression techniques, DCDTS has the potential to triple their pattern volume (test application time) compression (reduction) rate. Area/performance overhead and technical obstacles to automation are minimal. An automated sensor selection procedure is proposed, with reasonable CPU time.     

Fault Models and Test Procedures for Flash Memory Disturbances

Disturbances are special type of faults that are unique to flash memories. Causes of the disturbances are defects within the insulating layers of the memory element. These defects result in abnormal behavior of a memory cell under specific conditions. This paper describes characteristics of these defects as well as their manifestation as DC-Programming, DC-Erasure, and Drain Disturbance. We develop fault models to capture the behavior of faulty flash memories. We introduce three different fault models based on the underlying defects in a memory cell. These models are: Simple, Exclusive and General Fault model. Further, we develop test algorithms that detect disturbance faults under each of the fault models. The test algorithms reported in this paper for the simple fault model for each type of disturbance require optimal number of program, read, and flash operations; where as the algorithms for the remaining two fault models require near optimal number of these operations.
