Electronic Design - Talking about simulation optimization from the perspective of PCB design

Talking about high-performance mobile phone simulation optimization from PCB design

PCB board is the basic component of electronic products, and its quality is directly related to the function and life of electronic products. In the past two years, the focus of the PCB market has shifted from the fields of computers and communications to mobile terminals such as smartphones and tablets. At the same time, electronic products, including smart phones, are increasingly becoming smarter, thinner, and more sophisticated. With the increasing complexity of the system, it will bring greater design difficulties to PCB designers, and it will be difficult for them to find problems in the early stages of design and development.
1 Feasibility analysis before design

It is understood that for different PCB board types and IC platform solutions, the same mobile phone or several teams at the same time are working on several different PCB design solutions. When there are multiple PCB solutions that need to be evaluated, the preliminary feasibility analysis ( Placement and routing channel evaluation) will rely on experienced engineers to spend a lot of time.
In addition, with the current research and development of an electronic product, the PCB board size is getting smaller and smaller, and the number of components has increased significantly, which also brings a lot of trouble to the PCB design. On the premise of 100% deployment rate, many factors such as signal quality and manufacturability must also be considered. On the premise of ensuring quality, it is also necessary to pursue higher cost performance, which adds greater difficulty to the project. These problems will lead to a large proportion of the pre-evaluation time in the entire product development cycle.
There are two traditional evaluation methods: one is to judge based on experience, and the disadvantage is that the evaluation result is not accurate enough; the other is to evaluate based on the actual layout. This method is accurate, but it takes too long. In addition, the above two methods both face the shortcomings that the evaluation cannot be carried out collaboratively and the evaluation results are difficult to be reused.
How to quickly and accurately carry out the preliminary evaluation and obtain a feasible design plan is an important move to accelerate the launch of the product. To this end, Mentor brings an efficient layout platform based on Xpedition. With the help of this platform, time can be saved while satisfying accurate evaluation. The evaluation results can also be directly reused by the subsequent design team to accelerate product design. Experiments have proved that the traditional evaluation method requires two to three weeks, and the use of Mentor's evaluation program will shorten the time within one week, which is equivalent to saving two-thirds of the time for the customer.
Why does Mentor's platform have unique advantages? On the one hand, most of the current mainstream mobile phone chip manufacturers are developing based on Mentor’s Xpedition platform. Therefore, when their products are handed over to downstream mobile phone manufacturers, if the latter also use the Mentor platform, they can directly reuse the reference design, and Make accurate assessments. On the other hand, the Xpedition platform has numerous tools and complete functions, which can accelerate evaluation and improve efficiency.
It is understood that the current mainstream mobile phone manufacturers have basically adopted Mentor's platform solution for the preliminary evaluation of mobile phone design.
