Intelligent enhancements for conventional layout systems to support the design of printed circuit boards

In designing printed circuit boards (PCBs) several important aspects need to be considered. First of all the desired functionality of the PCB has to be realized. This central task is supported by conventional PCB layout systems. Furthermore, the design process is influenced by two factors: the available manufacturing equipment; the estimated prime costs of production for the PCB. These two aspects have also to be drawn into consideration by the designer. Looking at conventional layout systems there is no support available for these tasks at the moment. The designer has to rely completely on his own experience and knowledge. This paper presents a Computer Aided Design Environment (CADE), which enables the designer to gain information about the manufacturing restrictions and the estimated prime costs of production. Making use of the acquired information, he is able to review his design decisions and if necessary revise the layout
