Computers, cell phones and smart devices may not be properly built or updated without hardware engineer expertise. Hardware engineers create computer machines and technologies used to run software and store data on varying scales. Here’s what to know about a hardware engineer’s needed skills, salary and how to become one.
Consider the placement and compatibility of the components, technology, and systems
Hardware engineers are usually part of a designated hardware team within a company. They often collaborate with IT professionals and software engineers to accomplish their work. They also may report to senior hardware engineers or hardware engineering project managers. As consumer demands smaller and more powerful devices increase, hardware designers face the challenge of integrating complex functionalities into compact form factors. This requires innovative design techniques, advanced packaging technologies, and multi-domain expertise. Skipping or rushing through the testing and validation phase is a recipe for disaster in hardware design.
Industry-Led Best Hardware Design Practices
One of the top challenges of developing a production-ready hardware design is providing the ability to support any future enhancements. The enhancements or changes could pertain to the design, functionality of the component, memory, power consumption, and more. Designing a product that is difficult or costly to manufacture can lead to production delays, increased costs, and potential quality issues. Ignoring Design for Manufacturability (DFM) guidelines can hamper the scalability and efficiency of your design.
The Hardware Design Process
We usually do four or five sketches to gather feedback before settling on something the customer really wants. The last important thing in the PRD is that it’ll cover each of the four components of your prototype, which you’ll read about next. It means that you should try outsourcing because looking for a reasonable rate partner in your own country is a bad idea.
However, prototypes don’t always have all of these parts (see example below). For instance, an iPhone case would only have a plastic component and none of the others would matter. Or maybe you are just trying to launch an educational development kit (such as the Arduino), so you don’t really need a case or software. The production phase is all about taking your working prototype and building thousands and thousands more of them. You will probably need to refine your design even more and work with manufacturers that specialize in high volumes. It's often necessary for commercial telecommunications and consumer electronics to require extra testing to make sure they won't injure a user or take down a network.
Hardware Development Guide — The Design Phase
That means it’s hard for us to estimate how long it would take to prove out the concept before trying to design it. Chances are you’ve chosen to invest in rapid prototyping because it allows you to create tangible products from your computer-aided (CAD) files, as opposed to just 2D drawings, with a relatively quick turnaround time. This means exporting manufacturing friendly files out of your design tools, placing orders for your PCBs and bill of materials, and arranging to get it all assembled. To design a piece of hardware you will need to create models of the silicon chips you are using. These models usually live in a library, inside your CAD design tools, and should represent the real world chip or component as closely as possible. We live in a very different world from building hardware just a decade ago...
Connecting various sensors, communication modules, and actuators in a secure and power-efficient manner demands specialized hardware design skills. In the detailed design phase, designers create detailed schematics, component footprints, and PCB layouts. They perform simulations, analyze thermal and electrical characteristics, and verify the design against specifications. Collaborating with other teams, such as software and mechanical engineers, helps ensure a cohesive system design.
Manufacturing and Production
And most programmers will know that these firmware design problems can take forever to figure out. See for yourself what type of files we generate for the PCB portion of a hardware product. It’s not like we can just go to a 3D printer and hit “print.” Every time we have an error we need to address, we have to make a new version, make a new bare board, populate it, program it, test it, rinse and repeat. After a bit off nervous waiting you will get your prototypes back from the manufacturer and get to start debugging them.
They are usually accurate and allow the designer to catch issues before layout or manufacturing. Hardware design and development is an iterative process that is dependent on several compatible components, systems, and technologies. Component placement is another critical element you should consider, as it impacts functionality, quality, and symmetry. Hardware engineers design, build and test all hardware components of computers and related devices. Manufactured hardware can include circuit boards and processors, computer routers, gaming consoles, mobile devices as well as Internet-of-Things (IoT) devices. The proliferation of IoT devices presents new challenges and opportunities for hardware designers.

Adherence to the standards ensures interoperability and functionality. The development standards you put in place should act as a guideline that has to be followed mandatorily. However, with time, standards evolve, and your hardware design solutions should also keep up. To make sure there is no ambiguity in understanding the requirements or developing the process flow, it is important to have detailed and meticulous documentation of the hardware design. The greatest upside of documentation is keeping an eye on the pain points, anticipating next-in-line processes, and adherence to guidelines.
You can refine the hardware design using HDL-supported blocks and functions in Simulink and MATLAB. You can also use off-the-shelf libraries of optimized IP for signal processing, wireless, video/image processing, and deep learning applications. Many developers use various combinations of all of these, depending on the application’s needs.
Selecting the components based on their capabilities might take some time, but it is worth the time and effort in the end. Design engineers need to have an understanding of these latest technologies to adapt and incorporate them into the design process. Hardware engineers make necessary technology that is used by professionals almost every day.
This is where crowd-funding and pre-sales platforms like Kickstarter can help. Your manufacturer you will need you to export a package of files for them from your CAD tools. These files will document the physical features of your product and allow them to fabricate it for you. Unless you have a reason to keep it private, at this point we strongly recommend sharing your design with the world.
Testing and validation are integral parts of the hardware design process. Rigorous testing ensures that the design functions as intended meets performance specifications, and is reliable. Various techniques, including functional testing, electrical testing, and environmental testing, are employed to validate the design’s functionality and robustness. Iterative testing and refinement help identify and resolve any issues or performance gaps. It's often necessary to try-out an idea without actually manufacturing a circuit board or chip. Simulation engines use physics models to mock-up the behaviour of electronic components.
You can verify each step in the process versus the previous step or the original algorithm. You can reuse any of the representations to help the hardware design team verify their handwritten HDL code, via techniques such as HDL cosimulation or verification component generation. You can also prototype the hardware-ready implementation model on FPGA or SoC hardware connected to MATLAB or Simulink by running FPGA-in-the-loop testing.
