    PCB ArtistFree

    PCB Artist is an advanced PCB layout software that comes in handy if you are an engineer or engineering student. It saves the cost of manufacturing actual PCB design by making a virtual working electronic circuit. The two main features of PCB artists include the ability to create a schematic and layout. A schematic is a detailed visual representation of all the components the user would include in their layout. Schematics include the wire connections between each component, net names, and classification of the signal for the layout as a power, signal, or ground signal.

    Another highlighting feature of PCB artist is Advanced Circuit that continuously updates the library in each software update to maintain the most recent components on the market. PCB Artist also includes the footprints of many general components that a user can use to refine to specific ports. The process for PCB design is to first create a list of parts you will use in the circuit, then search for these parts in the libraries available. If the parts are not in any of the available libraries, you must create the components. This includes making a schematic symbol, a PCB symbol, and then creating a component that will connect the two together in order for the program to relate the schematic to the PCB design. All in all, PCB Artist is a lightweight yet handy tool for simulating PCB designs.
