Abstract(in English) Hierarchical test generation is an efficient method of test generation for VLSI circuits. In this work, we propose a reduction method of hold controls for hierarchical testable design based on strong testability of register-transfer level (RTL) datapaths. We improve the algorithm, which is a part of the DFT/test plan generation algorithm [4], for generating a controlling forest without time conflict. The improved method attempts to share hold registers with as many modules in time conflict as possible, while reducing the number of time conflicts. As a result, it can reduce the number of controls for hold registers, even though the number of time conflicts may increase. Experimental results show that the proposed algorithm is effective in reducing the number of controls of hold registers, so that it can reduce hardware overhead of the test controller.
