The old format, limited by 16-bit and 32-bit internal integer fields, by its inefficient representation of cell-native geometric figures, and by high structural overhead, was becoming difficult to use for leading-edge designs, and file sizes were becoming unwieldy, in some cases growing to many tens of gigabytes. The successor format was chartered with several overall goals:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAchieve at least an order-of-magnitude file size improvement compared to GDSII Stream.\u003c\/li\u003e\n\u003cli\u003eRemove all 16-bit and 32-bit integer width restrictions—make the new format fully 64-bit capable.\u003c\/li\u003e\n\u003cli\u003eEfficiently represent cells with large payloads of flat native geometric figures.\u003c\/li\u003e\n\u003cli\u003eProvide a richer information palette to facilitate interchange of layout-related information between design and manufacturing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align:justify;\" dir=\"ltr\"\u003e \u003c\/p\u003e\u003cp style=\"text-align:justify;\" dir=\"ltr\"\u003eIn the months leading up to the formation of the SEMI Data Path Task Force, International SEMATECH sponsored a series of meetings focusing on Mask EDA issues.
