我在寻找任何算法或可视化工具（NICE）电路/方框图图。

I'm looking for either algorithms or visualization tool for (nice) circuit/block-diagram drawing.

我也有兴趣在这个问题的一般提法。

I am also interested in a general formulation of the problem.

按线路图，我的意思是探索地方和放大器的能力;路线块图（矩形）与I / O端口和它们的连接（丝）。这些块图可以是分级的，即某些块可能有一些嵌套内部子结构等

By "circuit drawing", I mean the capability of exploring place & route for block-diagrams (rectangles) with I/O ports and their connections (wires). These block-diagrams can be hierarchical i.e some blocks may have some nested internal sub-structure etc.

此主题密切相关的经典图的图中，与有必要采取端口位置考虑进去的附加约束，以及可能的块的形状（不同大小的矩形）。 Graphviz的工具不应对这一问题（至少我的previous实验都不能令人满意）。

This topic is strongly related to classical graph-drawing, with the supplemental constraint of the need to take ports location into account, and possibly the shape of the blocks (rectangle of various sizes). Graphviz tools do not respond to the problem (at least my previous experiments have not been satisfactory).

力导引算法保留了我的注意，但我刚刚发现古典向图的论文。

Force-directed algorithms retain my attention, but I have just found papers on classical directed graphs.

任何提示？
