如何控制 circuitikz 中两个引脚之间的路径

Question

myIC我使用库创建了名为 的自定义电气元件circuitikz.sty。myIC有三个引脚，分别标记为、PinA和一个默认标签。我在环境中定义了此组件，这样我就可以轻松地将其合并到环境中。PinBPinCmyIClabelpgfdeclareshapecircuitikz

问题：我如何修改路径以遵循虚线蓝线而不是黑线？请注意，黑线已通过此命令创建：\draw (myIC1.PinC) -| (myIC2.PinA);。请参阅下面的输出屏幕截图

代码：

\documentclass[border=0cm]{standalone}

\usepackage{circuitikz}

\pgfdeclareshape{myIC}{
    
    % define saved anchor
    % ----------------------------------------
    \anchor{center}{\pgfpointorigin}
    
    % define Connectors relative to the center
    % ----------------------------------------
    % Pin A:
    \savedanchor\myICpinA{\pgfpoint{-30}{10}}
    \anchor{PinA}{\myICpinA}
    % Pin B:
    \savedanchor\myICpinB{\pgfpoint{-30}{-10}}
    \anchor{PinB}{\myICpinB}
    % Pin C:
    \savedanchor\myICpinC{\pgfpoint{30}{0}}
    \anchor{PinC}{\myICpinC}
    
    \foregroundpath{
        
        \pgfpathrectanglecorners{\pgfpoint{-30}{-30}}{\pgfpoint{30}{30}}
        \pgfusepath{draw}
        
        \pgftext[left,  at={\myICpinA}]{PinA}
        \pgftext[left,  at={\myICpinB}]{PinB}
        \pgftext[right, at={\myICpinC}]{PinC}
        
    }
    
}

\begin{document}
    \begin{circuitikz}
        % Instance of the custom component in red
        \draw (0,0) node[myIC, red] (myIC1) {};
        % Another instance in green
        \draw (3,0) node[myIC, green] (myIC2) {};
        
        % connecting pins
        \draw (myIC1.PinC) -| (myIC2.PinA);
        
    \end{circuitikz}
\end{document}

您可以手动执行：绘制一点然后-|或者|-使用最近的ext.paths.ortho库。

\documentclass[border=10pt]{standalone}

\usepackage{circuitikz}
\usetikzlibrary{ext.paths.ortho}

\pgfdeclareshape{myIC}{
  % define saved anchor
  \anchor{center}{\pgfpointorigin}
  % Pins
  \savedanchor\myICpinA{\pgfpoint{-30}{10}}
  \anchor{PinA}{\myICpinA}
  \savedanchor\myICpinB{\pgfpoint{-30}{-10}}
  \anchor{PinB}{\myICpinB}
  \savedanchor\myICpinC{\pgfpoint{30}{0}}
  \anchor{PinC}{\myICpinC}
  \foregroundpath{
    \pgfpathrectanglecorners{\pgfpoint{-30}{-30}}{\pgfpoint{30}{30}}
    \pgfusepath{draw}
    \pgftext[left,  at={\myICpinA}]{PinA}
    \pgftext[left,  at={\myICpinB}]{PinB}
    \pgftext[right, at={\myICpinC}]{PinC}
    % my static label
    \pgftext[center, at={\pgfpoint{0}{35}}]{\small\textcolor{black}{\pgfkeysvalueof{/mm/myLabel}}}
  }
}
\pgfqkeys{/mm}{myLabel/.initial=myIClabel}

\begin{document}
\begin{circuitikz}
  % Instance of the custom component in red
  \draw (0,0) node[myIC, red, /mm/myLabel=coch] (myIC1) {};
  % Another instance in green
  \draw (3,0) node[myIC, green, /mm/myLabel=gwyrdd] (myIC2) {};
  % Yet another instance in blue
  \draw (6,0) node[myIC, blue, /mm/myLabel=glas] (myIC3) {};
  \draw (myIC1.PinC) -|- (myIC2.PinA);
\end{circuitikz}
\end{document}
