EAGLE stands for Easily Applicable Graphical Layout Editor. The most popular and common CAD software for PCB designing is EAGLE. These software are widely used for PCB designing and simulation of the electronics circuit. Here we are discussing some most commonly used EDA software like EAGLE, Multisim, EasyEDA, Altium design, OrCAD, and KiCAD. Today there are many tools and software available online and offline for PCB designing that can help you design and fabricate PCBs with ease. We have already learned about the Basics of PCB in our previous article, in this article, we will discuss and compare some popular PCB designing software for their price, usability and other features. To solve this issue, PCBs were introduced back in the year 1936. But as the circuits became larger and more complex it became extensively hard to build reliable connections using externals wires. Until they change their on-disk file formats and library formats to remedy this problem and bind the symbols and footprints together, I do not recommend using Kicad.When PCBs were not discovered, engineers connected all components on a circuit using external wires similar to how it is done on a breadboard today.
It's basically the worst possible implementation, and it comes from the fact that Kicad consists of several independent programs that happen to exist in the same repository. And it's impossible to implement any kind of automated checks to ensure that the footprint assignments are sensible, aside from checking the pin count. For example, transistor pinouts can vary, even in the same package, so you can't simply switch the footprint, you also have to go back to the schematic and switch the symbol. Since there is no "mapping layer" between the symbol pins and footprint pins, you have to have to be extremely careful, and you'll likely have a whole stack of the same symbol, except with different pins numbering, to deal with footprint variations. The separation between footprints and symbols is one of the worst "features" of Kicad.
