    • A method for designing a semiconductor integrated circuit is provided that is capable of a timing simulation that is approximate to an actual operation by reducing the effect of IR drop on the timing without reducing an effective area necessary for arrangement of elements or the number of pads that can be used other than power supply pads and without increasing the processing time. In a FF driving ability change procedure, a flip-flop having a delay time larger than a transition time from a state in which an IR drop occurs in a power supply voltage to a state of an ideal power supply voltage is substituted for an arbitrary flip-flop. Thus, a delay library considering IR drop may be produced previously only for the flop-flop, thus enabling a production time of the library to be reduced and improving the calculation accuracy of the delay time in the delay calculation procedure. Furthermore, the substitution of a flip-flop having a low driving ability enables the area to be reduced.
    • 提供了一种用于设计半导体集成电路的方法,其能够通过在不减少元件排列所需的有效面积的情况下减少IR降低对定时的影响而实现近似于实际操作的定时仿真或者焊盘的数量 可以使用电源垫以外的处理时间。 在FF驱动能力改变过程中,具有大于从电源电压中的IR降低到理想电源电压的状态的转变时间的延迟时间的触发器被替换为任意翻转 -flop。 因此,考虑到IR降低的延迟库可以仅在触发器中产生,从而能够减少库的生产时间并提高延迟计算过程中的延迟时间的计算精度。 此外,替代具有低驾驶能力的触发器使得能够减小面积。

    • Where there are wirings with different film thicknesses or a sheet resistance in a non-scraped state of a wiring layer cannot be obtained as a result of the CPM technique, a wiring resistance according to a film thickness when an LSI is manufactured is acquired by automatic processing to reduce its difference from a real resistance, and accurate voltage drop analysis is carried out to reduce malfunction in a real chip. In a semiconductor circuit device with a plurality of kinds of film thicknesses in the same wiring layer, with a variation occurring in the wiring film thickness when wirings are formed on a silicon wafer, or a warp occurring in an upper layer because the stacking of lower layers is not uniform in the manufacturing process of the wiring, an error of the wiring resistance due to the difference in the film thickness or warp of the wiring is corrected to produce a virtual layout data.
    • 在采用CPM技术的情况下,由于不能获得具有不同膜厚度的布线或布线层的无刮擦状态的薄层电阻,因此通过自动获取当制造LSI时根据膜厚度的布线电阻 处理以减少与实际电阻的差异,并进行精确的电压降分析以减少真实芯片中的故障。 在同一布线层中具有多种膜厚的半导体电路器件中,当在硅晶片上形成布线时发生在布线膜厚度上的变化,或由于下层叠层而产生的翘曲 在布线的制造过程中层数不均匀,校正了由于膜厚度的差异或布线翘曲引起的布线电阻的误差,从而产生虚拟布局数据。

    • A facsimile device operable in either a memory receiving mode or direct receiving mode. When the device is put in a memory receiving mode after previous memory receiving, the image information transmitted next time is directly received, and thereby the repetition of the memory receiving mode and the retransmission of information can be eliminated and the convenience of memory receiving can be improved. A facsimile control portion detects a memory remaining amount of the image information memory available storing image information. When the absence of a memory remaining amount is detected, the occurrence of a memory over (operation in the memory receiving mode) is stored in the system memory. When the calling arrival occurs, the document is memory-received or directly received on the basis of the presence or absence of the memory over occurrence stored in the system memory.
