我正在寻找一种更好的方法来创建如下图像：
我想制作带有块和端口（带有希腊字母的东西）的图表，以便我可以执行以下操作：
- 不必手动划分块（在划分块时会自动考虑端口及其宽度）。
- 自动改变块的宽度和高度，以使它们足够宽以容纳所有端口。
- 以了解其位置的方式更改端口的形状/颜色。（例如，使用样式将块对面的端口颜色设为红色，或者将箭头放入的 NOT 圆圈设为红色。）
- 不要
tikzpicture不断地嵌套环境（这很烦人，而且一定有更好的方法。当我接触到端口有自己的端口的东西时，这一点会变得尤为突出。（端口可以有修饰符等来改变其含义））。
目前，我创建上述图表的代码非常粗糙且手动，随着我需要的图表越来越大，它变得越来越难。我主要在寻找关于如何利用 Ti 制作更模块化和可组合的结构的示例或建议钾Z，以及有关代码风格的建议。

答案1
您的问题不太清楚。请像下面我的 MWE 一样整理一下您的代码。然后针对您遇到的单个问题提出具体问题。例如：“如果端口是红色的，我该如何将其涂成红色多于一块砖头？
你可以从下面开始。我也尝试将其转换为更好的编码风格。
