Abstract:
Disclosed are a system and method for automatically and systematically generating device-based design rules and corresponding device-based design rule checking (DRC) codes. In the system and method, design rules associated with specific devices are generated based on at least one table of related data (e.g., maturity status information, restriction status information, etc.) for different devices. Based on the design rules and on unique definitions for the specific devices, design rule checking (DRC) codes associated with the specific devices are generated. By using this approach, comprehensive and accurate device-based design rules and corresponding device-based DRC codes can be quickly generated to ensure acceptable product reliability and yield. Furthermore, processes used to generate the device-based DRC codes can be iteratively repeated (e.g., when the information used for generating the unique definitions of devices and/or generating the design rules changes) to update the device-based DRC codes and, thereby ensure DRC accuracy.
