Trends in automotive electronics design
This article refers to the address: http://
In order to shorten time-to-market and lead the competition in competition, automotive electronics designers need to cope with the ever-changing needs of the electronics industry.
Electronic and semiconductor technologies continue to evolve, leading to rapid changes in electronics, mechatronics (electromechanics, electronics and software synergies) and tools for designing component systems.
Need to make the product more functional, but the product size can not be larger than the previous products and competitors' products, even smaller. Competition is driving the electronics industry to develop smaller but more functional devices. This requires product design tools to “use the physical space more economicallyâ€.
More features often mean higher electronics complexity and parts that need to dissipate heat. Due to market demand, even if new functions are added to the new model, the size of the product casing cannot be made larger, but it needs to be kept the same size or even smaller. In addition, greater packing density requires an increased level of detail at the component level to optimize proper fluid analysis.
New global environmental standards have emerged, such as RollS (Restriction of Hazardous Substances), which restricts the use of lead and other environmentally harmful substances and requires all that are sold and processed in the EU market as of July 1, 2006. The product must comply with the regulations.
As microcontroller systems continue to be miniaturized, more traditional hardware components, such as switches and displays, are being replaced by software features. For example, a couple of buttons were required a few years ago to operate a product, and now you can do it with two buttons plus an LCD display.
Challenges in the automotive electronics industry
ECAD systems are becoming more complex due to technological advances in the electronics industry. They are increasingly becoming expert systems, requiring operators to be very professional in their use to design.
Because mechanical engineers and electronic designers use different systems, there is a lack of interoperability between these systems, resulting in duplication of effort and an excessive amount of time to convert data between them.
The lack of interoperability between electronic engineering and mechanical engineering CAD systems results in inefficient products because electronic and mechanical designers will be added to the product. Repeated elements" to compensate for the lack of accurate information between the two systems.
In order to sell products in a global economic environment, international standards are expanding, not just including DIN.ANSI and ISO. Also including RoHS (Restriction of Hazardous Substances). In order to provide products to the market in a timely manner, it is necessary to know that electronic components and materials comply with this standard early in the process, as this involves cost and procurement issues.
Many electronic components have not yet formed a uniform industry standard. Nowadays, more and more 3D models are being built, but along with the geometric data, there is no standard to specify how to pass non-geometric properties (such as materials, standards of compliance, sources, etc.) that are embedded with the components.
Automotive electronics design process
The product development cycle is getting shorter so that the challenges and deliverables you face are different at every stage of the design cycle. You need to do more work in less time. Let's take a look at the basic electronics development process.
Identify component specifications - first and foremost, ask for new product concepts. This can be to improve the products currently offered, or to propose a new original concept (breakthrough technology). Part specifications can be determined at project startup, but more often with the creation of concepts. Determining component specifications is the initial attempt to define a product concept to effectively transform a concept into a product that is actually produced.
The next phase of package design is seen by many as the core of the conceptual design of the product design process. This stage of the product design process can be extended to include its own process, but for electronic product design, the appropriate concept is determined by the industrial designer and the mechanical engineer (this concept meets the requirements specified in the product brief and is also suitable for the requirements The square inch area-data was originally provided by the electrical engineer), and then they were prompted by the board size and shape.
PCB Design If PCB design is the core of the product design process, PCB design is at the heart of the electronic design process. After handing over the initial PCB layout (along with the location of the main components, connectors, and switches/interfaces) to the electrical engineering, the electronics engineer is responsible for the detailed design of the PCB and its interconnections. It is almost inevitable that PCB designers will make many minor (and sometimes significant) changes to the location of the components specified by the mechanical engineer. In addition, a evasive zone must be specified, and an agreement should be reached between the electronic engineer and the mechanical engineer to avoid encroachment and tracking. The initial design is then returned to the mechanical engineer via IDF.
Making a prototype - At some stage of the product design process, the design must be implemented in the form of a physical prototype. The prototypes come in a variety of forms, from mechanical enclosures to circuit test boards, to one-off, full-featured “near production†working models. This is an important milestone in the design process, and all disciplines are integrated into a single solution. The mechanical housing and the PCB and interface prototypes serve different important applications, including mating and finishing, thermal analysis, functional analysis (stress, drop testing, etc.) and assembly-oriented manufacturing. The prototype is also used in the key research groups to validate the concept.
Delivery to production - Finally, make customer documentation and manuals. This is another time-consuming and cumbersome process. If design changes occur later in the development cycle, these manuals must also be updated to maintain bill of materials information for spare parts and repair processes.
Of course, this is not a linear process. Driven by many factors, there are always many design iterations, including: changes in customer demand; internal engineering design changes: and changes requested by the manufacturing department and suppliers.
CAD/CAE integrated solution
SolidWorks provides solutions that interact with electronic product designs, reduce lead times, and reduce the number of expensive prototypes to be made throughout the design process.
Customers expect more features in their products, forcing electronics design manufacturers to include more features in their products, but the size of the product's casing is similar or smaller than previous models. This change, coupled with the pressure to bring products to market faster, requires designers and engineers to conceive, design, and deliver at a greater package density in a shorter product development cycle. You need to do more work in less time, and SolidWorksOffice Premium can help you achieve this.
Determining part specifications You can no longer afford the cost of bidding on a project for a few weeks. SolidWorks can quickly search for previous 2D and 3D designs to find relevant benchmarks so you can take advantage of previous projects to bid. By easily finding previous similar projects, you can quickly generate bidding drawings to more effectively estimate project costs and ensure revenue. 3 DContent Central offers a wide range of online components that will help you get started quickly and help you determine more accurate specifications. If you're searching for an outdated documentation catalog, then contact the vendor to get the latest version, and you might want to design the purchased parts to match the overall design, it's a waste of time. SolidWorks offers Toolbox and 3DContent Central, allowing you to find and import standard components (connectors, switches, mounts, IC components, etc.) and download them directly into 3D designs. So you can focus on designing instead of recreating OEM parts. You can provide more accurate bids before competitors; and use eDrawings to provide a digital version of the design, giving customers a deeper understanding of the design process. In addition, eDrawings provides annotation capabilities. A faster response and better customer interaction can help open the gap between you and your competitors.
Package Design Sol idWorks gives you a fast, flexible and easy-to-use solid modeling system that makes it quick and easy to create prototypes for your electronics. SWIFT technology helps you achieve the right design intent to help you focus on the competition and ahead of your customers' needs. On the design rather than on the MCAD system. The multi-body modeling approach speeds up the design process by allowing the conceptual design of different components to be quickly completed in the part stage (without having to go to the assembly stage). When you work in the assembly phase, SolidWorks allows you to dynamically position components with interference testing, making it easy to fill the PCB with the main components. PDMWorks tracks version changes throughout the design to ensure you can track your design. The relevance of solidWorks means that once a particular part or assembly is changed, the change is propagated to all appropriate documents and drawings, including drawings of parts and assemblies, NC documents, and customer manuals.
PCB Design Although SolidWorks does not meet the requirements for creating PCB layouts, the industry standard is that MCAD designers provide preliminary board layouts and provide interoperability between mechanical engineering and electrical engineering. SolidWorkS reads in the lDF file. As CircuitWorks joins the SolidWorks package, we can provide additional interoperability between mainstream ECAD packages and SolidWorkS. The strength of SolidWorks' world-class solid-model solutions, combined with ECAD systems, ensures that you can design better-quality electronics faster, without worrying about the duplication of effort and inefficiencies associated with non-interoperable systems. .
After the prototype is created to produce the initial design, proof of concept can be implemented by making a physical prototype. SolidWorks offers a number of tools that allow you to create “virtual†prototypes for your designs, reducing the number of expensive physical prototypes you need to make. Advanced collision detection tools, combined with COSMOSWorks and OSMOSFIoWorks for structural strength, vibration and thermal analysis, help you eliminate guesswork and problems even if you have not yet produced a physical prototype. When you need to make a physical prototype, part modeling, the synergistic combination of sheet metal, routing, and component assemblies together create a unified, fully defined and fully redefinable model, and customers can modify the model many times as needed. To solve, adapt and terminate assembly problems and thermal problems.
Delivery Production SolidWorks is very good at automating the creation of part drawings and cable harness drawings to fully document your product. Even after changes in the design cycle, modifications and changes to parts and assemblies automatically update documents and drawings and are managed by PDMWorks Enterprise to ensure that suppliers receive the most up-to-date information. PDMWorks Enterprise manages every aspect of design, from 3D parts, assemblies and drawings to assembly manuals to maintenance documentation. SolidWorks is committed to getting customers to work smoothly and transforming the final design into other industries. That's why SolidWorks offers a wide range of conversion formats (ensuring that your SolidWorks design is correctly and accurately converted to other manufacturing systems).
Through a large number of user data, the CAD/CAE integrated automotive electronic design solution has the following significant effects:
Reduce the time it takes for new users to get up to 50% - SolidWorks has one of the shortest learning curves in the industry. Mechanical and electronic designers who have no previous experience with MCAD can easily master the use of this tool within a week.
Reduce CAD licensing and maintenance costs - SolidWorks allows customers to get the most value for the least amount of money compared to any other MCAD system on the market. SolidWorks & COSMOS provides unparalleled functionality for electronic designers.
Reduce design cycle time by 40% while enhancing product aesthetics and packaging efficiency. As electronic design begins as a series of solid models and is maintained as an integrated, fully redefinable solid model assembly throughout the design cycle, As a result, dynamic interference and rich measurement tools can be used to understand the exact spacing and position to optimize PCBs, discrete components and interface components.
Reduce development costs by up to 30%. Because SolidWorks can "make virtual prototypes" to test interference, heat and assembly problems, it is possible to eliminate most of the guesswork before making actual physical prototypes, thus reducing iterative modifications. The number of prototypes.
Reduced processing time by two to three weeks SolidWorks provides manufacturing departments with very detailed and complete data specifications, as well as innovative and easy-to-manufacture parts and assembly drawings, as well as eDrawings and the industry's widest range of data conversion capabilities.
