WILSONVILLE, Oregon -- Mentor Graphics Corp. has said it will support a replacement data format for GDSII that it helped to develop in its Calibre product family and the IC Station tool suite in the first quarter of 2003. Mentor claimed that it has been instrumental in developing the replacement format, which is being introduced today (September 30, 2002).
An introductory event and party organized by the Semiconductor Equipment and Materials International industry body is scheduled to take place today at the Monterey Marriott Hotel, Monterey.
The interchange file format, sometimes called New Stream Format or Next Stream Format, is a replacement for GDSII, which has been used in the industry to transfer physical design data for 27 years (see September 12 story). It is expected to be used first used for the 130-nm, 90-nm and 65-nm process technology nodes .
To date, testing shows the new format achieving up to 10-50 times reductions in hierarchical data volume from GDSII, and up to two or more times reduction in flat data volume from MEBES mode5 format, Mentor said.
Mentor Graphics said it has made many contribution to the development of a new format including donating an initial specification, called 'version 3 SLF' and assigning Mentor employees to work with SEMI's New Stream Format Working Group. Mentor also contributed a GDSII-to-SLF translator to Working Group members, the company said.
"Calibre's leadership in resolution enhancement such as OPC optical proximity correction, entry in the mask data preparation market, and interaction with leading-edge IC customers triggered the internal development of a next-generation data format some time ago," said Joseph Sawicki, general manager of Mentor Graphics' design-to-silicon division, in statement. "We contributed our work in this area, without limitation, because we believe meaningful standards adoptions must be truly open. We are convinced this new SEMI standard format will improve the industry's ability to profitably build more advanced semiconductor products," he said.
"More than 40 people, representing over 20 companies, participated in the working group to develop this new interchange format. Mentor Graphics was involved from the inception, serving for many months as editor of the draft specification, and incorporating many successive sets of modifications for the working group,"said Kurt Wampler, chairman of the SEMI New Stream Format Working Group, in the same statement.
