In this paper, we propose a new clock tree synthesis method for semi-synchronous circuits. A clock tree obtained by the proposed method is a multi-level multi-way clock tree such that a clock-input timing of each register is a multiple of a predefined unit delay and the wire length from a clock buffer to an element driven by it is bounded. The clock trees are constructed for several practical circuits. The size of constructed clock tree is comparable to a zero skew clock tree. In order to assure the practical quality of the clock trees, they are examined under the five delay conditions, which cover various environmental and manufacturing conditions. As a result, they are proved stable under each condition and improve the clock speed up to 17.3% against the zero skew clock trees.
