    • A circuit from which a buffer and an inverter are removed without changing logic is displayed. Such a circuit is obtained by a first or a second method. With the first method, all buffers which do not change logic and, when a clock path is divided at a branch point of wiring, all pairs of inverters located on each divided clock path are removed from the clock circuit. With the second method, a logic element located on a plurality of clock paths is copied and added to the clock circuit, all buffers which do not change logic and all pairs of inverters located between logic elements other than the above buffers are removed, and redundant partial circuits, if any, realizing the same logic and being located on a plurality of clock paths are removed. Thus, the clock circuit can be displayed so as to facilitate a designer's understanding of logic.
    • 显示缓冲器和逆变器在不改变逻辑的情况下被去除的电路。 这种电路是通过第一种或第二种方法获得的。 利用第一种方法,不改变逻辑的所有缓冲器,并且当在布线的分支点处划分时钟路径时,位于每个划分时钟路径上的所有反相器对都从时钟电路中去除。 利用第二种方法,将位于多个时钟路径上的逻辑元件复制并添加到时钟电路中,除去不改变逻辑的所有缓冲器和位于除了上述缓冲器之外的逻辑元件之间的所有反相器对,并且冗余 去除实现相同逻辑并位于多个时钟路径上的部分电路(如果有的话)。 因此,可以显示时钟电路,以便于设计者对逻辑的理解。

    • The present invention is an apparatus and method to remove delay fluctuations generated on a plurality of networks.A reception apparatus 22 receives ATM cells transmitted through a network 4-1 and a network 4-2, converting the cells into a transport stream. At that time, the reception apparatus 22 expresses a PCR packet's timing of arrival at the reception apparatus 22 by a count value obtained as a result of counting the number of clock pulses (clock pulses Nr) synchronous with a network clock signal of the network 4-2. The reception apparatus 22 also computes a new PCR value W on the basis of the count value and the phase-difference information used as synchronization information. The reception apparatus 22 then computes a new PCR value X on the basis of an original PCR value E recorded from the beginning on the encoding side and the PCR value W, newly recording the PCR value X.
    • 本发明是一种消除在多个网络上产生的延迟波动的装置和方法。 接收装置22接收通过网络1-4发送的ATM信元和网络4-2,将小区转换成传输流。 此时,接收装置22通过计数与网络4的网络时钟信号同步的时钟脉冲数(时钟脉冲Nr)而得到的计数值来表示PCR分组到达接收装置22的定时 - 2。 接收装置22还基于用作同步信息的计数值和相位差信息来计算新的PCR值W. 然后,接收装置22基于从编码侧开始记录的原始PCR值E和新记录PCR值X的PCR值W来计算新的PCR值X.
