The power consumption and testability are two of major considerations in modern VLSI design. A full-scan method had been used widely in the past to improve the testability of sequential circuits. Due to the lower overheads incurred, the partial-scan design has gradually become popular. In this paper, we propose a partial scan selection strategy that bases on the structural analysis approach and considers the area and power overheads simultaneously. A powerful sample-and-search algorithm is used to find the solution that minimizes the user-specified cost function in term of power and area overheads. The experimental results show that our sample-and-search algorithm can effectively find the best solution of the specified cost function for almost all circuits, and the saving of overheads on average for each specific cost function is significant.
