But today better tools, design communities and reuse libraries mean you can find similar products, solutions and reference designs and start with a huge leg up. And, identifying the merging point can also play a critical role in the design process. In hardware design, one of the biggest challenges is the lack of an option to undo the process. It is a process because a sequence of steps is prescribed to produce or change the architecture, and/or a design from that architecture, of a hardware system within a set of constraints. Not all products require a software application to work — think of a Bluetooth speaker. To design it, we basically have to convert your product requirements into code.

Code Generation for Hardware Design

Because compiling hardware costs money (and takes time) it's important to check your design and make sure you haven't made a silly mistake. PCB layout is how to take a logical design (which parts are connected together) and turn it into a physical design (a 2D model of the real thing). It's similar to routing pipes and wires through a house after picking which parts of the house need water or power.

This often starts with a visual inspection, a multi-meter check, and a turn on test. It is not always possible to get a proper look at the chips or sensors since the hardware might pose visibility restrictions. The best workaround would be to design a debug hook into the device or build a logic analyzer into the chip. The cost of errors is too high, and it warrants a thorough design review to make sure all the bases are covered properly. A prototype could help in mitigating any rework, but there is no guarantee that a prototype will work exactly as anticipated during production.

Hardware Development Guide — The Design Phase

An average application can cost anywhere from $10,000 to $100,000. Yet, a lot of our products skip the POC if the product involves technology we know will work. If that’s the case, we’ll usually jump straight to the circuit board design. The POC's only purpose is to make sure that your product idea is doable using what is technologically feasible at the present moment.

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.

Second Component: The Circuit Board

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.

Hardware Product Design Takeaways

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.

What Skills Are Needed to Be a Hardware Engineer?

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.

Consider the placement and compatibility of the components, technology, and systems

Failure to thoroughly test and validate your design can result in undetected flaws, functionality issues, and unreliable performance. Implement comprehensive testing methodologies, including functional testing, environmental testing, and stress testing, to ensure the robustness and reliability of your design. Selecting the right components is paramount to the success of your hardware design.

Hardware designers need to carefully analyze power requirements, select appropriate power supply solutions, and implement power-saving techniques such as voltage regulation, energy harvesting, and sleep modes. The hardware design should be evaluated internally and externally. It is also important to build a feedback cycle into the system as early as possible so that you can make the necessary engineering or component changes. Hardware design is an iterative process that thrives on feedback between engineers and the design team. It is not unusual for a hardware design team to have more than 30 designers with varying specializations. These interdependent teams branch out to work on several smaller elements in the design process and then flow back.

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.

The sketch is often done by hand but some industrial designers use software. Overlooking thermal management can have detrimental effects on the longevity and reliability of your electronic designs. Excessive heat buildup can cause components to fail, leading to performance degradation or complete system failure. Incorporate proper heat sinks, thermal vias, and ventilation mechanisms to dissipate heat effectively and maintain optimal operating temperatures. Despite most products starting with an idea, its also often the smallest and simplest part of the whole project. As you bring your idea to life it will probably grow and change into something quite a bit different when you're finished!

When choosing critical components, thoroughly understand the datasheet and reference information to know the component limitations and capabilities. No matter how great an engineer or designer you might be, every design should be scrutinized. Relying entirely on prototyping could increase the project cost, push deadlines, and take longer to get the product to market.
