SAN JOSE, Calif. Mentor Graphics Corp. said Tuesday (Sept. 14) the upcoming version of its Calibre DRC/LVS tool accepts GDSII successor Oasis files and will support Oasis output in the upcoming 2004.3 production release scheduled for later this month.
The release includes the GDS-to-Oasis translator, which was previously made released for validation and verification.
The company said beta test partners, selected from among major semiconductor developers, foundries and mask manufacturers, translated thousands of files and proving overall flow efficiency and confirming a file size reduction by a magnitude of 10 to 50 times.
Mentor said it has so far provided more than 160 downloads of the GDS-to-Oasis translation utility, which is available free of charge on Mentor's Web site, and is generally used as a reference for Oasis-related development activities in the industry.
Now that the tool is production proven, the Oasis translator will be an included as a feature in the Calibre releases and made available to all Calibre customers.
Oasis was created in response to the need for more efficient handling of growing data volumes and is designed to replace the current GDS format.
This new encapsulated format promisies substantial improvements in data volume efficiency, up to a 50-fold reduction in hierarchical data volume compared to GDSII, and 2X and more reduction in flat data volume compared to mask writing formats.
Oasis is expected to become the new standard for data exchange between design teams, wafer manufacturers and mask suppliers, offering a new bandwidth in information exchange along with the most efficient data representation. It is also expected to help expand the emerging design-for-manufacture push in the EDA industry.
Mentor Graphics played a key role in Oasis development, donating the initial framework of the specification, serving as editor of the draft specification, then developing and contributing the translator utility.
Mentor's engineers have published several research papers on Oasis, and papers can be downloaded from the "tech papers"section of Mentor's Web site.
