PARIS STMicroelectronics NV (Geneva, Switzerland) announced it has licensed the PyCell architecture from EDA company Ciranova Inc. (Santa Clara, Calif) in order to provide PyCell-based physical design kits for advanced silicon technologies at 32-nm, 28-nm and beyond.
PyCells are Ciranova's form of parameterized cells as basic building blocks of analog design implementation. Ciranova interoperable PyCells are a next-generation approach to parameterized cell development for custom IC design.
Unlike older PCell approaches, Ciranova stated, the PyCell architecture is design-rule aware and generates DRC-correct device geometry automatically. PyCells run in any OpenAccess-capable EDA tool, and were selected as the physical foundation for the Interoperable PDK Alliance.
After ST evaluated PyCells for more than a year, Vincent Varo, CMOS and derivative PDK manager, Technology R&D, at STMicroelectronics, declared: "In some cases, using Ciranova’s API and PyCells have helped in reducing cycle time by several weeks in generating differentiated RF and analog elements, such as inductors, into ST’s first advanced 32/28nm RF PDKs. This has enabled our designers to start optimizing right away off the shelf 32/28nm analog and mixed-signal IPs ported from previous technology nodes."
Under the terms of the agreement, Ciranova said it will provide training and consultation, as well as contract PyCell development.
In March, Ciranova concluded a multi-year partnership with silicon foundry Taiwan Semiconductor Manufacturing Co. Ltd. to develop process design kit (PDK) technology based on Ciranova's PyCell architecture.
