A joint industry/academia consortium, supported by the European Union’s Seventh Framework Programme, has reported the successful conclusion of a three-year project and the release of its design-synthesis tool flow and related litho-friendly cell libraries and evaluation metrics. The SYNAPTIC research project includes eight partner organisations from across Europe and Brazil who have worked together to develop regularity-centric design methods and Electronics Design Automation (EDA) tools. The goal of the project was to reduce limitations in both logical and physical implementation effectiveness associated with technology scaling and advanced sub-wavelength lithography.
Through the development of new pattern-aware logic synthesis and implementation techniques, SYNAPTIC addressed critical problems such as systematic variability reduction, DFM (Design for Manufacturing) and yield improvement (at the cell, IP/macro, and system levels), sophisticated area/performance trade-offs, and system-level/architectural predictability and sign-off, for the European semiconductor industry. The goal has been to sustain the scaling predicted by Moore’s Law into advanced nanometer technologies.
The libraries, tools, and methodologies developed within the SYNAPTIC project can enable synthesis and implementation of several designs based on a reduced set of regular layout patterns with similar area, power consumption, and timing performance. These efforts have demonstrated that the beneficial impact of regularity on variability and manufacturability does not have detrimental effects on the other metrics. The yield metric and models developed in SYNAPTIC show that a significant yield improvement can be achieved for large process windows, which immediately translate into cost benefits, increased productivity, and faster time-to-market by reducing the effort on OPC (Optical Proximity Correction) before fabrication. The process flow developed by SYNAPTIC is stable and delivers consistent results, and is ready for an evaluation on industrial designs.
By successfully reaching all the milestones and enabling the exploitation of the regularity concept at different stages of design development and implementation, and in a new class of innovative synthesis and automatic library generation tools, the SYNAPTIC project has been instrumental in aligning the European semiconductor industry to global Integrated Device Manufacturers (IDMs) and Far East foundries, increasing the competitiveness of semiconductor and EDA companies in Europe.
