有 DAC 和 DAC 形状吗circuitikz？你知道，不规则五边形（边为三角形的线保证/矩形）。
尝试\pgfdeclareshape为其编写一个，但想知道是否有人已经这样做了。
一个缺点是，如果您尝试从它画线，它会占用边界矩形。还\tip为“三角形部分”的尖端设置一个锚点。
\tikzstyle{rectangulo}=[
draw, fill=#1, very thick, regular polygon, regular polygon sides=4,
text width=1cm, minimum width=2.25cm, minimum height=1.5cm,

答案1
这是否接近您想要的？我在这里找到了模型模数转换器。正如所提到的，解决方案将两个终端元素circuitikz之一修改 为两个宏，分别称为和，它们分别假设两个参数和。语法与下面的语法相同circuitikzgenericmyADCmyDAC<name><color>circuitikz
\draw (x1,y1) to[generic,color=white,name=<name>] (x2,y2);
\myadc{<name>}{<color>} % To replace the generic element
