  • Version management mechanism for fluid guard ring PCells
    Patent number: 9092586
    Abstract: A version management system for fluid guard ring (FGR) PCells uses one or more new version management parameters that are added to the FGR PCell definition to manage the source code versions for a PCell. The system saves instance layout information with a version management parameter that identifies the current PCell source code version for each FGR PCell instance. When evaluated using a newer version of the PCell source code, the instance layout information generated with a previous version of PCell source code can be retrieved. The retrieved layout information will be used during evaluation of the PCell to ensure the integrity of the PCell geometries that were previously verified. The saved layout information will be uniquely identifiable with a hash code of the name-value pairs for one or more parameters associated with the PCell instance.
