如何实现 tikz-timing 的分隔线？

我正在使用 tikz-timing 绘制时序图。我的最后一个图有点大，所以我在寻找分隔符来提高可读性。一些 HDL 模拟器和波形查看器支持该功能来对信号进行分组。

我当前的实现是硬编码的，我正在寻找一些关于如何概括此功能的建议。

这是我的波形： 波形 （可点击）

我当前的代码如下所示：

最后 16 行描述了分隔线。我想使用锚点来计算矩形框和文本节点，但我无法找到获取正确坐标的方法。

最好的解决办法是什么？

我认为最好的解决方案是有一个\divider{text}可以像这样放入空行的宏。

\\  % empty line for time scale
RefClock\_150MHz        & h 58{c}                          13c      92{c} \\
\divider{Transceiver Interface} \\
PowerDown                & [thick,violet]      lN(BA1)h 36H          hN(BA2)l  44L  \\
PowerDownDone            & [thick,orange]  28L  N(BB1)   8H      8H   N(BB2)   38L \\

第二最佳的解决方案是什么？

我认为拥有一个\divider[linenumber]{text}环境宏\begin{background}也可以解决这个问题:)。

\begin{background}[gray,semitransparent,semithick]
    \horlines{2,4,5,...,11,13,14,15,17,18,...,21,23,24,...,30,32,33,...,40,42,43,...,46}
    \vertlines{0,2,...,60,72,74,...,\twidth}

    \divider[color=bgred](2){Transceiver Interface};
\end{background}

PS
如果还有这样的时间尺度宏，那就锦上添花了：）

更新

现在\divider{text}执行以下操作：

  • 创建一个名为的节点text；
  • 创建一个名为left共享 y 坐标的节点(text)；
  • 创建一个名为right共享 y 坐标的节点(text)；
  • banner创建一个名为span the table from (left)to 的节点(right)；
  • 在里面创建一个节点(banner)并排版text。
  • 由于在表完成之前我们不知道它的宽度，因此除 之外的所有节点(text)都是在 之后创建的\extracode。
  • 如果有多个\divider，则相应地创建节点，并与相应的母节点。

\documentclass[border=60,tikz]{standalone}
\usepackage{tikz-timing}
\usetikzlibrary{fit}
\begin{document}
\makeatletter\gdef\dividers{}
\def\divider#1{
    N(#1)@{
        \g@addto@macro\dividers{
            \path(#1)-|node(left){}(all labels.west)(#1)-|node[shift={(0,1)}](right){}(all rows.east)
            node(banner)[fill=red,opacity=.2,inner sep=0,fit=(left.center)(right.center)]{}
            (banner.west)node[red!80!black,right](text){\scriptsize #1};
        }
    }
}
\begin{tikztimingtable}[timing/wscale=2]

    PowerDownDone      & [thick,orange]28LN(BB1)8H8HN(BB2)38L \\
                       & \divider{Synchronized Interface} \\
    CC\_Power Down     & [thick,orange]2LN(CA1)37HN(CA2)43L \\
    \\
\extracode
    \tableheader{Signalname}{Signalverlauf}\tablerules
    \draw[blue,->](BA1)to[out=0,in=180](CA1);

让我们开始吧。

\documentclass[border=60,tikz]{standalone}
\usepackage{tikz-timing}
\begin{document}
\def\strut{\large\vphantom{/}}
\begin{tikztimingtable}[timing/wscale=2]

    PowerDownDone      & [thick,orange]28LN(BB1)8H8HN(BB2)38L \\
                       & [opacity=0]0D{[fill=red,text=white,opacity=1,xshift=-8cm,right,text width=80cm]\strut\Large Synchronized Interface} \\
    CC\_Power Down     & [thick,orange]2LN(CA1)37HN(CA2)43L \\
    \\
\extracode
    \tableheader{Signalname}{Signalverlauf}\tablerules
    \draw[blue,->](BA1)to[out=0,in=180](CA1);
    \begin{background}[gray,semitransparent,semithick]
        \horlines{1,...,8}\vertlines{0,2,...,60,72,74,...,\twidth}
    \end{background}
