RT-Level Pattern Generation Scheme Using Hybrid Genetic Algorithms
Wei Lü · Journal of Chinese Computer Systems · 2006
The Register Transfer Level (RTL) behavioral descriptions are widely used in IC designs. In pattern generation for sequential circuits at RTL, simulation-based methods avoid the large search space used in time-frame expansion methods,but the quality of patterns can't be guaranteed often. This paper proposes a pattern generation method based on hybrid genetic algorithms. Firstly a global-local hybrid search mechanism is adopted in this system;secondly, many coverage metrics and RTL fault model are taken into account; thirdly, dynamic parameter settings are used to enhance the efficiency of the method. At last the experimental results show the effectiveness of the proposed method.
