    • A device for estimating the required number of board layer to provide necessary wiring in a printed circuit board or a LSI package, a system including the device, a method and a program for estimating the same. In this system, positional information of pins mounted to each component and a board, and connection information between pins are retrieved from a pin positional information file and a net list file. Further, information about an order of layers to be added, a diameter of a via in respective layers and obstacles to wiring is retrieved from the net list file an added layer structure defining file. Thereafter, information about a layer structure, vias, an area where wiring is prohibited is stored in a storage. A wiring route searching section determines whether or not it is possible to form necessary wiring under the present structure. When the wiring route searching section determines it to be impossible, a layer in the next order is added according to information about added layers. Subsequently, the wiring route searching section judges the possibility again. When determining it to be possible, the wiring route searching section outputs the present layer structure to an output device. By this means, it becomes possible to estimate a layer structure and the number of layers.
    • 一种用于估计所需数量的电路板层以在印刷电路板或LSI封装中提供必要布线的装置,包括该装置的系统,方法和用于估计该装置的程序。 在该系统中,从引脚位置信息文件和网络列表文件检索安装到每个部件和板上的引脚的位置信息以及引脚之间的连接信息。 此外,从网络列表文件检索关于要添加的层的顺序,各层中的通孔的直径和布线的障碍的信息,添加层结构定义文件。 此后,存储有关层结构,通孔,禁止布线的区域的信息。 布线路径搜索部确定在本结构下是否可能形成必要的布线。 当布线路径搜索部确定为不可能时,根据关于添加的层的信息,添加下一顺序的层。 随后,布线路径搜索部分再次判断可能性。 当确定可能时,布线路径搜索部分将当前层结构输出到输出装置。 通过这种方式,可以估计层结构和层数。

    • A behavioral synthesis system has a scheduling unit and a mode control unit. The scheduling unit performs scheduling of a behavioral level description with reference to a resource quantity data indicating resource constraint and a resource delay data indicating delay times of respective resources. A single process described in the behavioral level description is divided into a plurality of description blocks, and a scheduling mode among a plurality of scheduling modes is designated with respect to each of the plurality of description block. The mode control unit refers to a mode designation code that indicates the designated scheduling mode and controls such that the scheduling unit performs the scheduling with respect to each description block in accordance with the designated scheduling mode indicated by the mode designation code.
    • 行为综​​合系统具有调度单元和模式控制单元。 调度单元参照表示资源约束的资源量数据和指示各资源的延迟时间的资源延迟数据来执行行为级别描述的调度。 在行为级别描述中描述的单个过程被划分为多个描述块,并且针对多个描述块中的每一个指定多个调度模式中的调度模式。 模式控制单元是指指示指定的调度模式的模式指定码,并进行控制,使得调度单元根据由模式指定码指示的指定的调度模式对每个描述块进行调度。
