IBM adopts Mentor's Calibre tech

Mentor Graphics Corp. announced that IBM has adopted its patent pending Calibre encryption technology for use with IBM's 90-, 65- and 45nm process design kits. Encryption is used to expand the range of data IBM can securely transfer to its foundry customers in support of design for manufacturing (DFM), design rule check (DRC), layout versus schematic (LVS) and extraction methodologies, while protecting valuable intellectual property.

Encryption can enable IBM and its customers to access information at a level that approaches the design and manufacturing functions of an integrated device manufacturer (IDM). Within this "virtual IDM" communications model, IBM's customers can access the information they need, such as proprietary device models to perform the DFM analyses required for performance and yield improvement.

"Calibre's encryption technology develops stronger ties between the fabless community and their foundry partners, which is necessary for success in 90nm and smaller process nodes," said Matthew Graf, manager of Design Automation Enablement for IBM Systems & Technology Group. "Foundry customers need access to data that allows them to design high-yielding silicon while foundries need to protect proprietary manufacturing process data. Without a secure vehicle to transfer this information, there is a reluctance to share data. Encryption provides the much-needed step toward two-way protected communication between designer and manufacturer."

Data protection is and has been a key concern for manufacturers in the DFM era in which designers gain responsibility for making layouts more robust for enhanced yield. To succeed at this task, designers must have access to foundry data, such as recommended rules, that may contain unique design or manufacturing recipes.

Mentor's Calibre technology provides both partial and full encryption capabilities. IBM is using partial encryption for DRC and parasitic extraction models. Encryption is said to be optimized across the entire Calibre design-to-silicon platform of tools, which includes DFM solutions, lithographic solutions and mask data preparation tools.

"Calibre encryption capability is a critical enabler that allows foundries to protect their IP while enabling technologies such as DFM," said Joseph Sawicki, VP and GM of Mentor Graphics Design-to-Silicon division. "Calibre's leading design to silicon platform is uniquely suited for the latest technologies that require encryption, allowing protected communication between design and manufacturing."
