請參考第1圖與第2圖。第1圖係說明本揭示內容一實施例之佈局檢查系統100示意圖。第2圖係說明本揭示內容一實施例之佈局檢查方法200流程圖。佈局檢查方法200具有多個步驟S202~S208,其可應用於如第1圖所述的佈局檢查系統100。然熟習本案之技藝者應瞭解到,在上述實施例中所提及的步驟,除特別敘明其順序者外,均可依實際需要調整其前後順序,甚至可同時或部分同時執行。具體實作方式如前揭示,此處不再重複敘述之。佈局檢查系統100包含處理單元110與記憶單元120。記憶單元120用以儲存佈局檔。Please refer to Figure 1 and Figure 2. 1 is a schematic diagram of a layout inspection system 100 in accordance with an embodiment of the present disclosure. 2 is a flow chart illustrating a layout check method 200 in accordance with an embodiment of the present disclosure. The layout check method 200 has a plurality of steps S202 to S208 that are applicable to the layout inspection system 100 as described in FIG. 1. Those skilled in the art should understand that the steps mentioned in the above embodiments can be adjusted according to actual needs, and can be performed simultaneously or partially simultaneously, unless the order is specifically stated. The specific implementation manner is as disclosed above, and will not be repeatedly described herein. The layout inspection system 100 includes a processing unit 110 and a memory unit 120. The memory unit 120 is configured to store a layout file.
處理單元110電性耦接記憶單元120,並用以執行以下步驟。步驟S202,處理單元110由複數個零件名稱中擷取複數個電子特性(例如電阻值、電容值)字串。上述零件名稱對應於佈局檔的複數個零件(例如電阻、電容器)。舉例而言,零件為電阻,零件名稱可以是「1k_5%_2」,其代表零件的資訊。「1k」表示電阻值為1千歐姆(Ohm),「5%」表示電阻值公差(Tolerance)為百分之五,「2」表示零件具有兩個接腳(Pin)。此外,為了區別同一佈局檔內不同的電阻,每一電阻具有對應的零件代號,例如R4502、R1310等。The processing unit 110 is electrically coupled to the memory unit 120 and configured to perform the following steps. In step S202, the processing unit 110 extracts a plurality of electronic characteristic (for example, resistance value, capacitance value) string from the plurality of part names. The part name above corresponds to a plurality of parts of the layout file (for example, resistors, capacitors). For example, the part is a resistor and the part name can be "1k_5%_2", which represents the information of the part. "1k" means that the resistance value is 1 kilo ohm (Ohm), "5%" means that the resistance tolerance (Tolerance) is 5%, and "2" means that the part has two pins (Pin). In addition, in order to distinguish different resistors in the same layout file, each resistor has a corresponding part number, such as R4502, R1310, and the like.
具體而言,處理單元110可依照條件(例如零件代號含有「R」)選擇上述零件(例如電阻)。接著,處理單元110將所選零件的零件名稱擷取出電子特性字串(例如1k)。因此,處理單元110可有效率地擷取出佈局檔內所有電阻的電阻值。Specifically, the processing unit 110 may select the above-described parts (eg, resistors) according to conditions (eg, the part code contains "R"). Next, the processing unit 110 extracts the part name of the selected part from the electronic characteristic string (for example, 1k). Therefore, the processing unit 110 can efficiently extract the resistance values of all the resistors in the layout file.
於步驟S204,處理單元110將電子特性字串轉換為複數個電子特性數值。具體而言,由於擷取出的電子特性字串的屬性為字串,處理單元110可將屬性轉換為數值以進行後續的運算過程。舉例而言,處理單元110可將電子特性字串「1k」轉換為電子特性數值「1000」。In step S204, the processing unit 110 converts the electronic characteristic string into a plurality of electronic characteristic values. Specifically, since the attribute of the extracted electronic characteristic string is a string, the processing unit 110 may convert the attribute into a numerical value to perform a subsequent operation process. For example, the processing unit 110 can convert the electronic characteristic string "1k" into an electronic characteristic value "1000".
於步驟S206,處理單元110將電子特性數值與參考值比較以決定至少一特定零件。舉例而言,若使用者欲找出佈局檔內所有零歐姆的電阻,可設定參考值為零。處理單元110將步驟S204的所有電子特性數值與參考值比較以決定所有零歐姆的電阻(亦即特定零件)。於一實施例中,處理單元110將電子特性數值與參考值相減,並檢查相減結果是否等於零,以決定電子特性數值是否等於參考值。上述參考值、比較方式可依實際需求設計,本揭示內容不以此為限。In step S206, the processing unit 110 compares the electronic characteristic value with the reference value to determine at least one specific part. For example, if the user wants to find all zero ohm resistors in the layout file, the reference value can be set to zero. Processing unit 110 compares all of the electronic characteristic values of step S204 with a reference value to determine all zero ohmic resistance (ie, a particular part). In one embodiment, the processing unit 110 subtracts the electronic characteristic value from the reference value and checks whether the subtraction result is equal to zero to determine whether the electronic characteristic value is equal to the reference value. The above reference values and comparison methods may be designed according to actual needs, and the disclosure is not limited thereto.
於步驟S208,處理單元110列出特定零件。於一實施例中,處理單元110列出特定零件每一者之線路名稱、零件名稱與材料編號。舉例而言,處理單元110列出步驟S206決定出的零歐姆電阻、其所屬的線路名稱、零件名稱、材料編號等。於一實施例中,處理單元110列出每一線路的特定零件(例如零歐姆電阻)數量。At step S208, the processing unit 110 lists the specific parts. In one embodiment, processing unit 110 lists the line name, part name, and material number for each of the particular parts. For example, the processing unit 110 lists the zero ohm resistance determined in step S206, the line name to which it belongs, the part name, the material number, and the like. In one embodiment, processing unit 110 lists the number of particular parts (eg, zero ohms resistance) for each line.
實作上,處理單元110可以是獨立的微處理器(Microcontroller)或中央處理單元(Central Processing Unit,CPU)。記憶單元120可以是硬碟(Hard Disk)、光碟(Optical Disc)、或快閃記憶體(Flash Memory)。In practice, the processing unit 110 can be a stand-alone microprocessor or a central processing unit (CPU). The memory unit 120 can be a Hard Disk, an Optical Disc, or a Flash Memory.
綜上所述,本揭示內容得以經由上述實施例,準確且有效率地列出電路設計中特定電子特性數值的零件與其所屬線路。如此一來,不僅可縮短電路佈局的設計時間,亦可降低人為疏失的可能。In summary, the present disclosure enables accurate and efficient listing of parts of a particular electronic characteristic value in a circuit design and its associated circuitry via the above-described embodiments. In this way, not only can the design time of the circuit layout be shortened, but also the possibility of human error can be reduced.
