I. Collaborative Product Development Process Generally, collaborative refers to the ability of changing serial operation into parallel operation, and it has two modes. First model is let multiple designers to work simultaneously on the same design flow. It's not new in market, but it has big difference on efficacy compared before. Designers are always able to operate PCB design database and split, and every designer is working in design process. But the database must be re-combined, though it's very time-consuming and error occurs easily, it can shorten the design cycle at the end! Currently, we have the ability to let multiple designers work simultaneously in the same database, without having to split the database. It can be used for many PCB design process, such as schematics inputs, constraining inputs, management and physical layout. Besides, let designer see the real-time result of others. It not only significantly reduces the design cycle time, but also improve the productivity of the designers and quality of products. Some users' reports show that the technology saves 30 to 70% of the design time. Companies ought to get the similar improvement to keep competitive. The second model is the ability to run several different processes, and it's a parallel pattern which is different form sequences. Schematics, constraints, and layout analysis can be parallelized, thereby improving designer productivity better and shorten design cycles. However, this mode requires complex design data management which contains version management, synchronization, calibration, permissions, this will be explained later in this article.
