CIF (Caltech Intermediate Form) and GDSII (GDS) Stream Formats are standard layout description languages used to transfer mask-level layouts between organizations and design tools. The GDSII Stream format, has become the most popular layout description language for integrated circuit layouts. The “II” in “GDSII” means “2″. The name “GDS” refers to the company that introduced the GDS format (a subsidiary of General Electric originally as far as I know).
