我想画一个缓慢的上升沿来tikztimingtable显示触发器的亚稳态行为。
我尝试使用[timing/slope=1.0]但是上升沿宽度太窄。
\begin{tikztimingtable}
C1 & 3L l 5{5C} H \\
C2 & 4L 5{5C} h \\
A & 2L [timing/slope=1.0] 24H h \\
B1 & 3L l m MMMMM 4L l 16H \\
B2 & 4L MMMMM 20H h \\
\end{tikztimingtable}
以下是最接近我想要的东西。
问题是我无法消除信号 A 中的那个小尖峰。
\begin{tikztimingtable}
C1 & 3L l 5{5C} H \\
C2 & 4L 5{5C} h \\
A & 2L !{-- +(3,1)--++(3,0)} 24H h \\
B1 & 3L l m MMMMM 4L l 16H \\
B2 & 4L MMMMM 20H h \\
\end{tikztimingtable}
当我将线条的第二个点的 y 值保留为 1 时，就像这样!{-- +(3,1)--++(3,1)}，下面的高层会设置一个高于它的线条高度。（由于我只能发布 2 个链接，所以无法发布图片...）
- 是否可以将参考点设置在正确的位置，以便我可以继续使用 H、L、M 等？
- 另一个解决方案可能是绘制信号 A 的整个时间。这是最好的方法吗？
答案1
我在尝试绘制混合信号波形时遇到了同样的挑战。我花了一段时间才熟悉了多层语言（tikz、pgf 等）。我认为你离答案很近了。
我现在无法测试代码，但我认为你只需要使用“--++”而不是“-- +”
\begin{tikztimingtable}
C1 & 3L l 5{5C} H \\
C2 & 4L 5{5C} h \\
A & 2L !{--++(3,1)--++(3,0)} 24H h \\
B1 & 3L l m MMMMM 4L l 16H \\
B2 & 4L MMMMM 20H h \\
\end{tikztimingtable}
我创建了这个独立的 tex 源，演示了我学到的所有技巧。如果上面的答案不正确，你应该可以通过比较我的例子来发现。

我认为您的解决方案将与我的这个示例类似（查看第 7 条轨迹的绿-蓝-红部分）：
{'Analog' Drawing: Additional lines anchor to last stopping point; "- - + +" \textcolor{red}{!!USE THIS<<}} &
[gray] LL;
[green] !{--++(1,0)};
[orange] !{--++(1,1)};
[blue] !{--++(1,0)};
[yellow] !{--++(1,-1)};
[pink] !{--++(1,2)};
[green] LLHHLLH;
[blue] !{--++(1,-2)};
[red] HLLHHLLH;
该 tex 的输出如下：
我希望它可以为您节省我花在弄清楚上的许多时间！
