Abstract(in English) | As LSI chips become larger and faster, the effect of delay variations on the circuit behavior becomes larger. The consideration of delay variations is requested in semi-synchronous circuits that use the difference of clock delays effectively, too. In this paper, we propose a clock tree construction method that takes delay variations of a long time constant into account. In the proposed method, first, an objective clock schedule is obtained under the assumption that delay variations of clock delay are proportional to the wire length, but that the delay variations on the common part of clock wire to a register pair with signal propagation do not affect the circuit behavior. Then, a clock tree is constructed so that the clock schedule realized by the clock tree approaches the objective clock schedule. In experiments, the validity of the proposed method is confirmed. |
