In the world of electronics, we can divide the job profiles in Chip Design into three main parts: designing the physical boards, designing integrated circuits, and creating software. These three components are board design, IC design, and software design. Each of them is really important in shaping how our modern technology works.
In this blog post, we will delve into the intricacies of hardware (board design), VLSI (IC design), and embedded systems (software design).
Additionally, we will explore the nuances between fixed ICs (ASICs) and flexible ICs (FPGAs) and understand how their characteristics impact electronic systems.
An analogy to Job Profiles in Chip Design
Imagine building a house. In the world of electronics, it’s like constructing a high-tech mansion. You have three key roles:
Architects (Board Design): They plan and design the layout of rooms, where each room represents a different part of the electronic device. They decide where the kitchen (processor), bedrooms (memory), and entertainment rooms (peripherals) should be for the house to function smoothly.
Interior Designers (IC Design): These specialists focus on the details inside each room. They decide the type of furniture (transistors) and how everything is arranged. Some furniture is fixed in place (ASIC – like custom-made cabinets), while others can be moved around and rearranged (FPGA – like modular furniture).
Programmers (Software Design): Now, you need someone to make sure everything inside the house works seamlessly. The programmers create a set of instructions for the inhabitants (the device) to follow. They determine how the lights (functions) should turn on, how the thermostat (control systems) should work, and more.
Just like in building a house, these three roles in electronics – board design, IC design, and software design – work together to create a well-functioning and efficient electronic device, much like a smart mansion tailored to meet specific needs.
3 Job Profiles in Electronic Chip Design
1. Hardware Design (Board Design):
Hardware design, often referred to as board design, involves the creation of physical circuit boards that serve as the foundation for electronic devices.
This encompasses the layout and interconnection of electronic components, including microprocessors, memory modules, and various peripherals.
Hardware designers need to consider factors such as power consumption, signal integrity, and thermal management to ensure the reliability and efficiency of the electronic system.
The term “hardware” collectively refers to the physical components of a device, distinguishing it from the software that runs on it. Hardware designers play a crucial role in optimizing the performance and functionality of electronic devices.
2. IC Design (VLSI):
Integrated Circuit (IC) design, also known as Very Large-Scale Integration (VLSI), focuses on the creation of miniature electronic circuits on a single chip. VLSI technology has significantly advanced, allowing the integration of millions or even billions of transistors on a single chip. This miniaturization has enabled the development of powerful and compact electronic devices.
IC design is further categorized into two types: Fixed ICs & Flexible ICs.
a. Fixed ICs (ASIC – Application Specific IC):
An Application-Specific Integrated Circuit (ASIC) designs for a particular purpose or application, differing from general-purpose ICs like microprocessors or memory chips. They find use in situations where standard off-the-shelf components might not meet specific performance, power, or size requirements.
ASICs are used in a wide range of applications, including telecommunications, automotive systems, consumer electronics, medical devices, and more. For example, a chip designed specifically for processing graphics in a gaming console would be an ASIC.
b. Flexible ICs (FPGA – Field Programmable Gate Array):
FPGA stands for Field-Programmable Gate Array.FPGAs, a type of integrated circuit (IC), allow users or designers to configure and reprogram them after manufacturing, providing flexibility compared to ASICs with fixed functionality designed for specific purposes.
FPGAs find applications in a variety of fields, including telecommunications, aerospace, automotive, medical devices, and more. They are commonly used for tasks such as digital signal processing (DSP), cryptography, network processing, and hardware acceleration.
While FPGAs offer flexibility and rapid prototyping capabilities, they may not achieve the same level of performance or power efficiency as custom-designed ASICs for specific tasks. The flexibility comes with a trade-off in terms of resource utilization and power consumption.
3. Software Design (Embedded Systems):
Software design in the context of electronics refers to the development of embedded systems. Embedded systems are specialized computing systems designed to perform specific tasks within electronic devices. These systems often run on microcontrollers or microprocessors embedded within the hardware.
Embedded software is responsible for controlling and coordinating the functions of the electronic device. It interacts directly with the hardware to execute specific tasks efficiently. The design of embedded software requires a deep understanding of both hardware and the intended application.

In the intricate world of electronics, the collaboration between hardware (board design), VLSI (IC design), and embedded systems (software design) is essential for creating innovative and efficient electronic devices.
Understanding the distinctions between fixed ICs (ASICs) and flexible ICs (FPGAs) provides valuable insights into the trade-offs between performance and adaptability in electronic system design. As technology continues to advance, the synergy between these three components will play a pivotal role in shaping the future of electronics.
