Objectives of Digital Systems

1. Using boolean functions we are able to design digital systems.
2. They help us in designing combinational circuits.
3. They help us in analyzing synchronous and asynchronous communication: With the help of digital systems we get to analyze 
4. Understanding Programmable Logic Devices (PLDs): We overcome ASIC(Application Specific Integrated Circuits) in order to overcome we have PLDs As in the case of ASIC we had 2 complex connections that were taking up more space. With the help of PLD, we can design combinational and sequential circuits. PLD is a special type of IC programmable by the user.

We are living in a world where we are surrounded by computational going all around and devices connected to the internet to what we refer to as IoT(Internet of Things). Even our IoT devices are changing so rapidly these days with the technology stack of machine learning and artificial intelligence. It is because of digital systems. Digital systems consist of digital circuits that process data physically stored in binary format. Now we do have certain principles in system design in order for designing digital systems. 

• Digital systems are fast.
• Digital systems are accurate.
• Digital systems consume less power.

Digital principles in system design invoke the study of different concepts, and techniques used in designing digital systems. 

Goal Of Design Systems: It is to be a single source of truth for the product( or say organization) . In order to achieve that designers and developers need to collabrate as they both have to speak same language. Gradually they start improving the collabration process for product  to get designed.  Everyone (designers and developers) comes on a single designers and developers.
