PREVENTING DOUBLE PATTERNING ODD CYCLES |
摘要 |
A method, system or computer usable program product for preventing odd cycles caused by design modifications to a double patterning layout including utilizing a processor to identify a set of double patterning cycles in the layout for storage in a memory; receiving a set of design modifications to the layout; utilizing the processor to identify from the set of double patterning cycles a subset of double patterning cycles affected by the set of design modifications; utilizing the processor to identify from the set of design modifications a subset of design modifications which may cause odd cycles in the subset of double patterning cycles; and providing a notification of the subset of design modifications. |
