What is ESD?
Embedded system design (ESD) is the process of designing the architecture, software, and hardware of an embedded system. ESD includes the design of the software that runs on an embedded system, including the operating system and applications. This design also includes hardware design, in which engineers determine how each component of an embedded system will function.
Why is embedded system design important?
The importance of embedded system design is that it enables a wide variety of applications to be created and functional for solving complex problems. ESD is the skill set required by those who design, implement and manage the software that runs on embedded systems.
What is the role of an embedded system designer?
An embedded system designer’s role is to understand their project’s requirements and then create a solution that meets those requirements. They need to be able to take raw hardware and software specifications, translate them into a hardware design or software specification, and then turn this into a working system.
Embedded System Designers have many responsibilities, including:
- Analysing user requirements to understand what they need from their product
- Creating an outline for each aspect of the product (i.e., hardware, software, firmware)
- Developing design documentation for each component of the product (including schematics and bill of materials)
- Developing test plans for testing each component of their product before it goes into production
What is the Embedded Systems Design Cycle?
The embedded system design cycle is a six-step process used to create electronic products. Here the designers try to explain the embedded system design cycle from analysis of requirements to testing and acceptance.
- Requirement Analysis
The first step in the embedded system design cycle is to analyse requirements. This involves reading through all the documents that were required for the project and reviewing them with the client or customer. The analyst needs to be able to clearly define what needs to be done, who will do it, and when it must be done. The analyst also needs to determine if there are any constraints on time, cost, or space that need to be considered during this step of the process.
After analysing requirements, the next step in the embedded system design cycle is schematic design. During this step, an engineer draws out a schematic diagram based on what was determined during the analysis of requirements. A schematic diagram includes all electrical circuit elements such as resistors, inductors, capacitors, switches and transistors. Schematics also includes interconnections between components as well as power supply lines for each component type (e.g., 3V for an LED).
- PCB design
The PCB design process is a key step in the embedded system design cycle. PCB designers often work closely with engineers and other staff members to create the board layout, which is a type of electronic circuit board. A PCB layout is used to connect electronic components and make them work as intended.
The prototype is a working model of the system that can be used to test the design and its purpose. It is also used to demonstrate the final product to potential users. The prototype should be built using the same materials and components as those used in the final product, but it should not be as complex or expensive.
- Firmware Development
The firmware is what runs on the hardware and controls its functions. This can include both software and hardware components that are made for embedded systems in various industries, such as automotive, medical, industrial automation and home appliances. The firmware may be developed by someone else or by the manufacturer, who then packages it up into a single file that can be downloaded onto your device via USB or other means.
The final phase of the design cycle is testing and acceptance. A product is not considered complete until it has been tested, and if it does not pass this stage, then it will be rejected by the customer and will never be shipped.
Testing can be carried out by a variety of groups, including internal and external customers, as well as internal staff members who are involved in the process, such as quality assurance engineers, software developers and test engineers. Testing is arguably the most important step in the ESD process since this is where you can guarantee the acceptance of the product by the users and make the product flawless. Hence when you are out selecting the best-embedded training institute in Chennai with placement guarantees or at any other place, make sure that the training institute offers lectures on testing aspects of the ESD process.
