Software cuts MEBES file size, data transfer times

SoftJin has announced the latest product in its line of EDA componentsthe MEBESzip, a software product that compresses mask data files in MEBES format by a factor of 5-15X and reduces file size as well as data transfer times. MEBESzip also allows selective decompression, eliminating the need of decompressing the entire file prior to use for any further processing.

MEBESzip addresses the challenge of handling increasingly large Manufacturing Electron Beam Exposure System (MEBES) files sizes in the nanometer design era. It converts mask data in MEBES format into a highly compressed proprietary binary format. The binary format can be decompressed back to recover the original bit- for-bit matching MEBES file.

Data explosion
As per the ITRS roadmap of 2005, for a 45nm half-pitch node that is expected to be in use by 2010, the mask data volume for a single layer is expected to reach up to 825Gbytes. The industry needs solutions that can deal with this enormous data explosion. Compression techniques better than generic and commonly used compressors like gzip will be required to address this problem. In recent benchmarks, comparing against generic compressors such as gzip, the MEBESzip has been consistently producing compression factors ranging between 2 times and 8 times better than gzip, with an average of 4 times better compression across all tests runs. The compression ratio by MEBESzip is found to be dependent upon the CAD tool that generated MEBES data in the first place.

By compressing MEBES files by a factor of 5-15x, MEBESzip reduces the time taken to transfer these files across mask shops, foundries and manufacturing-related groups within integrated device manufacturers (IDMs). MEBESzip reduces the disc space requirements for storing and archiving of MEBES files within these organizations.

Selective Compression and De-Compression MEBESzip allows for segment-wise selective compression and decompression of MEBES files. This feature in conjunction with API-based integration with upstream and downstream EDA tools enables on-demand reading of compressed MEBES data without having to decompress the entire file before being able to operate on the data.

Enhanced security
MEBESzip provides an optional in-built verifier that provides on-the-spot verification to check the fidelity of the compressed file. CRC-32 based checksum and MD-5 based fingerprint schemes are used in MEBESzip for verifying the data integrity. MEBESzip offers the option of in-built data encryption and decryption to enhance the security during transfer of compressed data.

MEBESzip is targeted to mask shops or mask-related groups at IDMs and foundries. It is available today and is licensed in executable form as a standalone product or in object code form along with an API for companies that wish to integrate and sell it as part of their post layout tools. Currently, it is also available for a one-month free evaluation.
