定义我自己的自定义白盒数字电路组件

Question 1

取决于您的用例的复杂性以及您需要多少个形状……这里有一个开始。

答案如下：

借用了（仅仅是借用了形状和锚点）rectangle ee的定义的形状声明。circuits.eerectangle.input.output

我也借用了链接示例用于形状定义内的文本。锚点用设置\pgfpointlineattime（这类似于pos沿直线的键，或符号内的因子calc）($(<p1>)!<factor>!(<p2>)$)。

如果您有更多这样的形状，并且需要沿矩形边框设置多个不同的锚点，则可以使用形状声明中的 fey 键和循环进行序列化。这也适用于文本。
现在我们有了带有锚点和文本的形状，我们可以使用它了。对于合适的电路形状，我们用声明一个符号，circuit declare symbol并用进行设置set <symbol name> graphic。

键circuit symbol size设置minimum width和minimum height相对于circuit symbol unit（引擎盖下的 TeX 尺寸）。这使得它相对于其他电路符号可扩展。transform shape需要键来使其沿circuits'to路径旋转。
path picture使用来自的建议代码我的另一个答案。设置随节点旋转和缩放的局部坐标系：坐标(0, 0)位于节点中心。X向量指向east（= output），是指向北锚的向量。这对于坐标规范很重要，(left:.2)因为它使用了.2节点水平尺寸的一半和应用的旋转。

内部的电路符号path picture获得选项gray（线条也是如此），并且circuit symbol unit=.1cm会将符号缩小到合适的大小。可能需要调整此值以获得正确的大小。也可以使其依赖于上述局部坐标系，其尺寸为\pgf@xx和\pgf@yy。

显然，如果您需要具有相同锚点和连接布局但具有不同门的多个符号，则可以根据三个值键使形状定义具有可延展性，在本例中将其设置为not gate、nand gate和nor gate。

我已经用过我的paths.ortho图书馆对于内部的连接path picture。显然，您可以使用任何方式连接这些线路。
