[0069] 由于第一档案2及第二档案3都是Excel格式档,因此,该检查程序4可利用VBA 程序来撰写,使其可以根据“是否有连接测点”观的字段例如图2所示的Nail (s)字段28, 先从该第一档案2中筛选出没有连接测点12的元件接脚点10,然后,再以该些元件接脚点10 一一比对于该第二档案3的“重要性Priority33”字段,便能找出哪些元件接脚点10在第二档案3中被要求“绝对需要连接测点12”,但实际上却没有连接任何测点12。 [0069] Since the first and the second Item 2 Item 3 is Excel format file, therefore, may utilize the checker 4 VBA program to write, it can "whether connection measuring point" View of two fields, for example, FIG. Nail (s) shown in fields 28, starting with the first file in the selected element 2 measuring point 12 is not connected to pin point 10, and then again to the plurality of pin element 10 eleven point than that of the second file to the "the importance of Priority33" field 3, will be able to find out which element pin 10 points in the second file is required 3 "absolutely need to connect the measuring point 12", but in fact it is not connected to any 12 measuring points.

[0070] 该检查程序4也能够根据如图3所示的第三档案5中找出相同群名的电源测点120,例如Net Name为+5V者,并计算出每一群电源测点120的电源测点总数量67,最后将该电源测点总数量67相较于该安全数量47,以决定出哪一个电源测点总数量67不足而需要再追加电源测点120,以图3而言,群名为+5V者的电源测点120有一个,不足预定的安全数量47 “5个”,所以该群电源测点120需要再追加4个电源测点120。 [0070] The check program 4 can also identify the same power measuring point name group 120 according to a third file 5 shown in FIG. 3, for example, by Net Name is + 5V, and a group of power calculated for each measuring point of 120 the total number of power measurement points 67, and finally the total number of power measurement points 67 47 as compared to the number of the security, to determine which of a total number of the measuring points 67 is less than the power required measuring point and then an additional power supply 120, FIG. 3 in terms of , the group's name + 5V power supply 120 has a measuring point, less than a predetermined number of safety 47 "5", so that the power measuring point group 120 need to supply additional four measuring points 120.

[0071] 再者,该检查程序4更能够从第三档案5有关测点12的测点X坐标52、测点Y坐标53、测点型式M、测点面积56、布线网络的名称58等记录中,计算出相邻两测点12间的间距值69与该安全间距值49的差值65,藉以判断有哪些测点12的间距值69是不符要求的例如低于50mil。 [0071] Further, the program checks 4 can be more files from a third measuring point about 5 X coordinate of the measuring point 52, 12 of the Y coordinate measuring point 53, M type measuring point, the measuring point area 56, the name of the network wiring 58 and the like 69 with the security distance difference value 49 of the recording, the two measuring points the distance between the calculated value 12 adjacent 65, so as to determine which spacing values ​​are 69 measuring points 12 are non-compliant example, less than 50mil.

[0072] 最后,该检查程序4能够产生一报告7,该报告7亦为Excel格式档,因此,可以接收及记录上述的检查结果。 [0072] Finally, the program checks 4 can generate a report of 7, 7 also in Excel format of the report file, therefore, may be received, and recording of the test results. 在图7中,显示该报告7的实质内容,其包括三个部分,分别为: In FIG. 7, the substance of the report 7, which comprises three parts, namely:

[0073] 第一部分:用以报导有哪些元件接脚点10绝对需要追加测点12的。 [0073] Part I: has been reported to pin-point member 10 which is absolutely necessary to add 12 to the measuring point. 图中“PCI_ CK_33M_LPC”即为被要加入测点12的对象。 Figure "PCI_ CK_33M_LPC" shall be added to the object of measurement points 12.

[0074] 第二部分:用以报导有哪一群电源测点120的电源测点总数量67少于安全数量47"5个”,而需要增加电源测点120的。 [0074] Part II: for a group which has reported the total number of power measurement points than the number of power measurement points 67 Security 47 "5" 120, power needs to be increased to 120 measurement points. 图中名称为+5V的哪群电源测点120共仅1个,比安全数量47 “5个”少,所以需要再增加4个电源测点120。 Fig group which name is a + 5V power measuring point only a total of 120, the number of security than 47 "5" less, it is necessary to add four power measuring point 120.

[0075] 第三部分:用以报导有哪些测点12的间距值69是低于安全间距值49 “50mil”, 而需要加大间距值69。 [0075] Part 3: What spacing value reported for the measuring point 12 is lower than the safety spacing value 69 49 "50mil", and the need to increase the spacing value 69. 图中显示共有4个是不合格的测点12。 The figure shows a total of four measuring points 12 is unacceptable.

[0076] 此外,需特别指出的是,上述第三档案5的资料亦可合并输入第一档案2中,也就是说只利用第一档案2来定义该电路布局1。 [0076] In addition, particular note is the third data file 5 can also be input to the first merging two files, i.e. files using only the first 2 to define the circuit layout 1. 如此只需增加第一档案2的字段,便同样能据以执行检查程序4而获得该第一部分、第二部分、及第三部分所表达的讯息。 Thus simply increasing the first file field 2, they can, according to the same procedure to perform the check 4 to obtain the first portion, second portion and third portion of the message expressed.
