An open design tool for analog circuits

An analog design automation system is presented. The system is capable of designing, analyzing and optimizing analog circuits in MOS, bipolar or BiCMOS technologies. Its main feature is that it is open to the user's expertise. The expertise that can be introduced is knowledge concerning the topology and functionality of a customer circuit, which can be complemented with knowledge about its device sizing sequence. Due to the fact that it is open, it assists and encourages designers in storing their expertise in a structured way, so that it can be reused. The tool includes Monte-Carlo analysis algorithms which ensure an extensive verification and characterization of the design. >
