    en.wikipedia.org/wiki/List_of_free_electronics...

    List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.

  3. Open-source hardware - Wikipedia

    en.wikipedia.org/wiki/Open-source_hardware

    The FOSSi Foundation is founded in 2015 as a UK-based non-profit to promote and protect the open source silicon chip movement, roughly a year after the official release of RISC-V architecture. [27] The Free Software Foundation has suggested an alternative "free hardware" definition derived from the Four Freedoms. [28] [29]

  4. LTspice - Wikipedia

    en.wikipedia.org/wiki/LTspice

    The advantage of this method is the 3rd party model is self-contained as part of the schematic when you distribute the schematic file. The same .model can also be copied to an ASCII text file on your computer too, [19] but it won't "travel" with a schematic when you copy it to another computer. For example, the following diode part numbers aren ...

  5. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    Once the schematic has been made, it is converted into a layout that can be fabricated onto a printed circuit board (PCB). Schematic-driven layout starts with the process of schematic capture. The result is what is known as a rat's nest. The rat's nest is a jumble of wires (lines) criss-crossing each other to their destination nodes.

Connectors on this cable would be designated:

  7. Schematic capture - Wikipedia

    en.wikipedia.org/wiki/Schematic_capture

    Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit, is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor. [1]

  8. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  9. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
