Proceeding of IEEE Workshop on Design and Diagnostic of Electronic Circuits and Systems

Register Transfer Level, Feedback Loop, Genetic Algorithm

In the paper, two different methodologies for the identification of registers to be included into the partial scan chain and principles of their implementation are described briefly. One of them is based on the utilisation of genetic algorithms, the other one on the identification of feedback loops. An attention is paid to the computation of time and space complexities of the developed algorithms. The possibility of the complete state-space exploration (all possible scan chain configurations) is also discussed. It is derived that algorithms based on genetic algorithms allow to gain sub-optimal solutions while fulfilling user requirements. The combination of both methodologies is investigated and the complexities analysed. Experimental results are described.
