# Electric circuits in TeX, LaTeX, and Friends

What are some ways to draw electric circuits in TeX systems?

I'm making this community wiki since I haven't found a question related to this.

I was thinking along the lines of circuitikz. What do you think of that? Other examples are more than welcome, of course.

I'd be interested to see examples comparing the different approaches, as well. –  Will Robertson Sep 29 '10 at 4:55
Well after a look into the manuals, Circuitikz is the most complete package in term of components. –  s__C Feb 1 '13 at 7:54

From version 2.10 on, TikZ has a circuits library. It seems to be based on CircuiTikz.

For users of Asymptote, there seems to be a new package for doing this, discussed here.

Thanks Will. I've been using Asymptote for a year now and really love it. Although I almost never use it inside of LateX. I generate the image in its own file and import it. Up to now I've been drawing my own circuit elements with it. –  bev Nov 26 '10 at 9:57

Since somebody has to do it, it might as well be me. How about TikZ or here?

+1; totally agree :) –  Geoffrey Jones Sep 29 '10 at 4:41
Considering that the examples do a \usepackage{...}, are these documented in texdoc pgfmanual? –  Kit Oct 4 '10 at 6:58
@Kit: I'm not sure. Take a look in the documentation. –  TH. Oct 4 '10 at 7:53

You may also want to have a look the pst-circ package from the pstricks family.

I have seen two Metapost-based circuit drawing environments:

1. Tomasz Cholewo's mpcirc, which is a suite of four minimally documented Metapost libraries to support writing Metapost to layout circuits. The examples are impressively compact, but I don't understand the code;
2. Gustavo Argañaraz' makecirc, which is a pair of Metapost libraries, to handle circuit layout and creating Latex labels. The code is much more what one would expect, and there is a user guide.

Makecirc is somewhat tied to Latex, because its label creation library uses latex-specific code to create parametric label ranges. Mpcirc should work with Context.

I would recommend circuit macros (https://ece.uwaterloo.ca/~aplevich/Circuit_macros/).

It is not a LaTeX plugin as circuitikz. The circuit drawing makes use of m4 (macro language) and dpic (PIC drawing language) to reach a LaTeX drawing file (e.g. tikz pgf commands actually).

The extra steps gives a lot of power and flexibility. And indeed the circuit symbols in Dwight Aplevich's M4 circuit macros look more pleasing. (https://ece.uwaterloo.ca/~aplevich/Circuit_macros/html/examples.html)

The biggest disadvantage is the multi-step processing. Besides than that it looks interesting and I'll have a look at it. –  s__C Jan 31 '13 at 21:46
The symbols look cool and the diagrams are beautiful, but the syntax is unintuitive. To place an element, you have to write something like {R18: resistor(up_ elen_*1.2); llabel(,R_{18}) } where 1.2 is the vertical shift from the current point (I think). –  Luigi Feb 4 '13 at 8:40
