生成结果：
我想要的是将加法器梯形放置在使得连接与门的输出和加法器的线始终垂直的位置。
谢谢你！
答案1
你必须使用命令
\draw (andgatherer.output)
-- ++(right:\patitas mm) node [midway,right,blue,below] {$E_n$}
-- (andgatherer-|addernode.south);
addernode.south是基线梯形的。由于梯形是旋转的，所以该点标志着梯形旋转后的左边界。(andgatherer-|addernode.south)表示从 开始的水平线andgatherer与从 开始的垂直线相交的点addernode.south。这正是从 开始的直线andgatherer应该结束的点。
这里有一个建议，如何使用来简化您的代码ciruitikz。
