Everyone at some point has had the thought of making a better gadget or device than what is already on the market, and some do start creating circuits if only just to learn how electronics work.
Too many other project structures, the design process is quite simple and similar.
Determining the task to be accomplished: Since every circuit is created for a purpose, be it educational, entertainment or practical, the purpose of the circuit to be designed is the first thing that should e determined. Depending on the complexity of the task, the project can be subdivided into individual functions that will work together to accomplish said task. For this reason you need to get the certified vlsi design course through professionals.
Selecting components: Now that you have the functionality figured out, it’s time to pick the right and necessary components to build the circuit. At this point it is still in the design stage, no components are bought just yet, only the datasheets and specifications of the components are required to design the circuit or subcircuit. This step is critical since all the tolerances and characteristics of the working project must be considered. Will the circuit be used in the heat? For resisting the mechanical stress (as in falling, shaking, etc), is it expected? If the circuit is to be battery powered is a major design issue, the components are chosen need to fit these characteristics and also the electrical needs of the project, such as the current draw.
Schematic Design: The electronic circuits are designed with their corresponding schematic diagrams in this stage. This is used as a guide for implementation and documentation since it is the one that will ultimately be made into an actual circuit board when it comes to the design in the schematic. This is one of the most challenging steps of electronics design, since many kinds of analysis need to be made in order for the circuit to work as intended. All those analyses require a certain level of technical knowledge and experience since sometimes even with all analysis correct, the experience can help you find situations that could potentially damage or make the circuit malfunction.
Circuit Board Design: The next step is to design the circuit board where the actual components will be soldered, now that the functional part of the circuit has been designed and represented with the schematic. For creating the circuit boards with a schematic, there are many automated tools. Manual design is very difficult, and with big projects with many components, it could become a nearly impossible task, especially if space is an issue. So, you need to undertake the asic verification course.
Prototyping, Testing, and Corrections: Another very important aspect of circuit design is prototyping and testing. Analysis and simulation sometimes give erroneous or inaccurate due to external circumstances that may have been overlooked during analysis such as mains hum, RF interference or other events created inside the circuit such as thermal noise, inductive and capacitive coupling, and many others. It allows you to find all those hidden characteristics of the circuit when it comes to prototyping and testing, so before massive production, it is incorporated in the design. All this helps reduce costs as it is easier to discard one unsuccessful prototype than it is to withdraw a whole shipment that may contain up to millions of units.
Since the function or characteristics of the circuit may change in the middle of the design, all of the steps can be revisited as needed or would take a lot of money or time to create or design the proposed design is way too complex.
