我怎样才能使我的逻辑电路看起来“更好”？

Question 1

@js-bibra 回答是一种减少纠结的优雅方法，所以去做吧，除非你希望输入严格在左边。

不过，我将发布对您的代码的修改，以展示如何进行最小的修改以使图表更清晰，以及如何“交错”电缆以避免覆盖垂直电缆。

诀窍是尽可能使用相对坐标，垂直坐标，然后“放大”一点，输入会导致一些输入。我在代码中注释了...

\documentclass[border=10pt]{standalone}
\usepackage[siunitx, RPvoltages]{circuitikz}
\begin{document}

\begin{tikzpicture}
\ctikzset{
    logic ports=ieee,
    logic ports/scale=0.6,
}

\draw

node[not port] (not1) at  (4,7.5) {}
node[not port] (not2) at  (4,6.5) {}
node[not port] (not3) at  (4,5.5) {}

node[nor port, number inputs=3] (norR) at (6,8) {R}
node[nor port] (norS) at (6,6) {S}
node[and port] (andT) at (6,4) {T}

node[or port, number inputs = 3] (orF) at  (8,6) {}

% use relative coordinates here, to align with port inputs

node[] (X) at ([xshift=-4cm] norR.in 1) {X}
node[] (Y) at (X|-andT.in 1) {Y}  % in the same place vertical as X!
node[] (Z) at (X|-andT.in 2) {Z}
node[right] at (orF.out) {F}

% not output connections (reverse for staggering, use .out anchor!)
(norR.in 2) --++(-0.5,0) |- (not1.out)
(norR.in 3) |- (not2.out)
(norS.in 1) |- (not2.out)
(norS.in 2) |- (not3.out)

(norR.out) -| (orF.in 1)
(norS.out) -| (orF.in 2)
(andT.out) -| (orF.in 3)

% connection the other way around to easily "stagger" them

(norR.in 1) |- (X)
(not3.in) |- (X)

(andT.in 1) |- (Y)
(not1.in)   --++(-0.5,0) |- (Y)

(andT.in 2) |- (Z)
(not2.in) -- ++(-1,0) |- (Z)

;
\end{tikzpicture}
\end{document}

无论如何，让我提出另一种变化。我喜欢使用输入轨当有多个变量时，为了使连接容易跟踪，并在连接它们时添加点（即使它们不是严格需要的，它们也会突出显示连接并清楚地表明裸露的交叉点就是交叉点）。

我也使用多个\draw命令，以便能够使用宏来简化事情并轻松创建循环。
