定義我自己的客製化白盒數位電路組件

Question 1

取決於您的用例的複雜性以及您需要多少個這些形狀……這是一個開始。

答案如下：

rectangle ee借用了定義的形狀聲明circuits.ee（這只是藉用了帶有和錨點的rectangle形狀）。.input.output

我也從連結借用範例用於形狀定義內的文字。錨點設定為\pgfpointlineattime（這類似於pos沿直線的關鍵點，或符號中的因子calc）($(<p1>)!<factor>!(<p2>)$)。

如果您有更多這樣的形狀，需要沿著矩形邊框使用多個不同的錨點，則可以使用 fey 鍵和形狀聲明內的循環來序列化。這也適用於文字。
現在我們有了一個帶有錨點和文字的形狀，我們可以使用它了。為了獲得正確的電路形狀，我們使用聲明一個符號circuit declare symbol並使用進行設定set <symbol name> graphic。

鍵circuit symbol size設定minimum width和與（引擎蓋下的 TeX 尺寸）minimum height相關。circuit symbol unit這使得它相對於其他電路符號具有可擴展性。需要鑰匙transform shape才能使其沿著circuits路徑旋轉to。
path picture使用建議的程式碼我的另一個答案。設定隨節點旋轉和縮放的局部座標系：座標(0, 0)位於節點的中心。這X向量指向east(= output)，y向量到北錨。這對於座標規範很重要，(left:.2)因為它使用.2節點水平尺寸的一半和所應用的旋轉。

內部的電路符號path picture獲得選項gray（與線條一樣），並且circuit symbol unit=.1cm確實將符號縮小到適當的大小。可能需要調整該值以獲得正確的大小。也可以使其依賴前述具有尺寸\pgf@xx和的局部座標系\pgf@yy。

顯然，如果您需要具有相同錨點和連接佈局但具有不同閘的多個符號，則可以根據三個值鍵使形狀定義可延展，在本例中這三個值鍵設為not gate、nand gate和nor gate。

我已經用我的paths.ortho圖書館對於內部的連接path picture。顯然您可以使用任何方式連接這些線。
