A wiring diagram is distinguished from an electrical schematic in that the arrangement of the schematic bears no necessary relationship to the mechanical arrangement of the electrical elements in the component. The wiring diagram provides an accurate picture of how the wiring on the components and between components should appear in order that the electrical wiring technician can install the wiring in the manner that will best contribute to the optimum performance of the device.

Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment.

Common circuit diagram symbols (with US Resistor Symbol)
Potentiometer Symbol on Circuit DiagramsOn a circuit diagram, the symbols for components are labelled with a descriptor (or reference designation) matching that on the list of parts. For example, C1 is the first capacitor, L1 is the first inductor, Q1 is the first transistor, and R1 is the first resistor (note that it isn't written R1, L1,…). The letters that precede the numbers were chosen in the early days of the electrical industry, even before the vacuum tube (thermionic valve), so "Q" was the only one available for semiconductor devices in the mid-twentieth century [verification needed]. Often the value or type designation of the component is given on the diagram beside the part, but detailed specifications would go on the parts list.On CNET: Which would you pick: Girl or gadget?

Wiring me?
April 29, 2005 10:52 AM Subscribe
I'm looking for recommendations for software that helps make electrical schematics.

In my work I often need to design wiring harnesses and power connections for various pieces of equipment. It's basic wires, connectors and circuit protection stuff, with the occasional black box or diode/resistor/capacitor network thrown in to keep things different. Right now I'm using a 2D mechanical drafting program (Solid Edge) that we've bought for other things. It's okay for making drawings, but when it comes to rearranging things, all changes must be done by hand (leading to mistakes or a lot of time lookimg for them) and there's no built-in symbol library, though I've developed most of the things I need over the years.

I'm demo-ing SmartSketch right now and finding it a bit too pricey and a bit too general (it maintains connections, but has no grouping function, for example, so moving a multi-pin connector is a bit of a pain). We also have a seat of Protel at work, and its $5000/seat price and emphasis on circuitboard design rather than power wiring makes it the wrong bang for a whole lot of bucks.

Any suggestions for a sub-$1000 electrical schematicafier?

Schematic Capture - Simulation - PCB Designer

AutoTRAX EDA is a powerful multiplatform integrated Electronic Design Suite for Electronic Engineers. It has all the features you expect and need to rapidly and easily take your design from conception through to production. It’s in-built hierarchical project manager lets you perform both top-down and bottom-up design and reuse design components and sub-systems.

Starting with its easy to use Schematic Capture mode, you can drag pre-created parts onto your design sheets and rapidly and reliably connected the terminals together using wires, buses and off-page connectors. AutoTRAX ensures that your design remains correct throughout with no dangling wires’ or design rule violations.

You can also create your own parts either in-place on your design sheets or using the integrated Part Creator. Again, design integrity is maintained throughout using the AutoTRAX’s design rule checker.

Once you have created your design you can rapidly simulate it’s analog performance using the build in virtual instruments such as oscilloscopes and signal generators. Multiple analyses can be produced using the industry standard SPICE 3f5 simulator that comes free with AutoTRAX.

When you are satisfied with your design and simulation results, you can then quickly proceed to produce your finished and populated PCB board without leaving the AutoTRAX program. The AutoTRAX PCB Designer will take your hierarchical design and place the components, with or without your assistance. Next AutoTRAX can either autoroute your board or you can use a combination of automatic and manual routing to quickly and reliably complete all electrical wiring. The design of AutoTRAX’s internal data ensures you main full electrical integrity with your schematic design. No surprises with lost or missing PCB tracks or wires, or those extra’ wires.

Now that you have your design finished and routed you can then produce all Computer Aided Manufacturing files you will need to produce the board, drill the holes, cut it’s profile, order parts using the Bill Of Materials, and place your parts using the pick and place files. These files can be place together and forwarded to your favorite board manufacturers, electronically via email.
