Simulation And Detection Of Printed Circuit Board Based On CAD

With the rapid popularization of electronic products, its design and manufacturing technology is constantly evolving. However, the process, from product design to production starts, it is necessary to put in a lot of human and material resources to amend the design, trial production and testing. As for some issues of design, such as if the layout is reasonable and beautiful, and if the design is in accord with the design criterion, generally, artificial solution, which to some extent constrained in the development of electronic products. If they can be analyzed and tested by means of computer-aided, it will help solve this problem.In this thesis, how to extracted data from Protel files as an example of electronic circuit CAD tools, and how to deal with the complexity of electronic components packaging standards are studied. According to these, the 3D graphics drawing is come true with OpenGL, the appearance simulation before the completion of the electronic product manufacturing is completed. Some non-functional issues in Protel design are studied, and the solutions are given. These studies have played a complementary role on the current electronic circuits CAD technology.From the depth and breadth of perspective, the study is more advanced in the field. Through the use of computer-aided tools, it can further save time and cost in electronic product R&D. It is of great significance.3D simulation of the graphic details does not study more accurate, the next step could achieve more real results. There are many complex problems in the error detection need study for further. A perfect solution would better resolve the issues of human factors in R&D. All in all, this is a very valuable research direction and a hot issue.
