Principle Difference between Analog and Digital Designs

Digital design and its analog counterpart have existed side by side for decades for decades now. During that time, the two are set apart by the presence of different approaches to each type as well as the great variations in tools used in designing them. There was no clear way to bridge the gaping chasm between the two. However, that fact has recently changed. It is reported that over 70% of integrated circuits used in many devices nowadays are of the hybrid of the two. With the ascent of Internet of Things, that percentage is expected to grow even bigger in the coming years.

Electronic devices and products now come with the ability to connect to the internet and a bundle of sensors—a fact that forces every designer in this planet to be able to come up with a way to make digital and analog systems to work together. This poses some challenges to overcome. Analog design is often regarded as more complex than its digital sibling. Whereas digital design can be developed simply with just a couple of taps on the keyboard, analog one requires its designer to have a fully working knowledge about the limitations their tools have.

Digital design depends greatly on how well-made the codes used in building it are, precision-wise. Meanwhile analog design requires the designer to understand how each basic component of the device works with each other. These are only to mention a few of major differences between the two but it is enough to depict how hard it is to combine them together. A plausible solution is to add digital design to components built using analog one. Combining an analog design to a digital chip (like one found on the microchip.com website) is proven hard because analog circuit defines a limitation as to how a device is to be routed or positioned.
