List of Principles in Designing Digital Systems
1. Boolean Algebra:
Boolean algebra is a branch of mathematics that deals with the computational logic of digital circuits. It helps us in easing out digital circuits.
2. Logic Gates:
They are building blocks for any digital circuits, they are building blocks for any digital circuits.
It is a process/technique of designing digital systems that perform a specific operation based on the input provided. Combinational logic gates are used in these systems to modify the inputs and produce the desired outputs.
The steps involved in combinational logical design are briefly described below are as follows:
- Understanding the requirements
- Truth Table
- Logic Expressions
- Simplification
- Gate level design
- Circuit Diagram
- Implementation and Testing
- Optimization and Documentation
Note: For more information in order to understand the construction of Combinational Circuits please refer here.
4. Sequential Logic Design:
The process of creating digital circuits or systems with memory that can store and process information over time is known as sequential logic design. Sequential logic uses feedback and the present state of the system to predict future behavior, in contrast to combinational logic, which just considers the current inputs. Combinational logic gates are used in these systems to modify the inputs and produce the desired outputs. The procedures involved in combinational logical design are briefly described below.
The steps involved in combinational logical design are briefly described below are as follows:
- Design the specification
- State diagram
- State Encoding
- Next state Logic and Output logic
- Memory elements
- Circuit Diagrams
- Implementation and Testing
- Optimization and Documentation
Tip: It is recommended to have good knowledge of differences between combinational and sequential circuits.
5. Integrated Circuit Design:
The process of developing electrical circuits that are compacted and integrated onto a single semiconductor chip is known as integrated circuit (IC) design. It entails creating the component’s internal structure, relationships, and functioning.
The steps involved in combinational logical design are briefly described below are as follows:
- Specification and Archietecture
- Logical Design
- Circuit Design
- Physical Design
- Verification
- Manufacturing and Fabrication
- Testing and Characterization
- Packaging and Integration
6. Microprocessor and Computer Architecture:
The microprocessor is an important part of a computer architecture without which you will not be able to perform anything on your computer. It is a programmable device that takes in input performs some arithmetic and logical operations over it and produces the desired output. In simple words, a Microprocessor is a digital device on a chip that can fetch instructions from memory, decode and execute them, and give results
7. Digital System Testing and Verification:
Testing in a digital system is computed with reconciliation with the utmost
8. Timing and Synchronization:
Timing and synchronization are important considerations when developing systems, especially digital systems where event sequencing and coordination are key. Here are some crucial ideas and methods for synchronization and timing in system design.
- Clock Signal
- Clock Domain Crossing
- Timing Analysis
9. System Integration and Interfacing:
System Integration is combining components to form a cohesive digital system, while Interfacing establishes connections for seamless communication between subsystems.
10. Power and Signal Integrity:
Power Integrity mainly focuses on ensuring Power Distribution Network (PDN) are as follows:
Specific design techniques are as follows:
- Proper Decoupling Capacitor Placement
- Impedance Control
- Power Plan Design
Principles in Digital System Design
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.
