Synopsys, Inc., a global leader providing software, IP and services used to accelerate innovation in chips and electronic systems, today announced that it has collaborated with TSMC to provide support for voltage-dependent design rules in TSMC's 16-nm Custom Design Reference Flow.
As part of TSMC's custom design infrastructure, TSMC has also certified Synopsys' Laker® custom design solution and circuit simulation tools that deliver new capabilities for TSMC V0.5 16-nm FinFET process layout design rules, device models, and electromigration and IR-drop (EM/IR) analysis. TSMC and Synopsys will continue to collaborate on certification of the Synopsys tool set until 16nm FinFET reaches V1.0.
"TSMC works with Synopsys to ensure our customers have access to analog and mixed-signal design tools for TSMC's 16-nanometer FinFET process," said Suk Lee, senior director of design infrastructure marketing at TSMC. "The Custom Design Reference Flow is another milestone of the long term collaboration between the two companies."
"Synopsys continues to build on our strengths in custom design," said Bijan Kiani, vice president of product marketing at Synopsys. "Designers rely on us to provide circuit simulation and RC extraction, and are increasingly looking to us as their complete custom design solution provider, particularly with the move to 16-nanometer process technologies."
Voltage-dependent Design Rules
For the TSMC Custom Design Reference Flow, Synopsys' HSPICE® circuit simulation, Laker custom layout and IC Validator physical implementation tools have been brought together to provide a comprehensive solution for voltage-dependent design rule checking. VDRC rules require larger spacing between signals that have a high potential voltage difference. For VDRC validation, voltage ranges are calculated for each net by HSPICE circuit simulation, annotated onto the layout by the Laker layout editor, and then verified using IC Validator signoff verification.
Laker Custom Design Solution Updates
Laker enhancements for 16-nm layout include an extensive set of new features for FinFET devices, including fin grid pattern snapping, fin display and interactive FinFET rule checking. Laker's built-in double-pattern checking has been enhanced to support pre-coloring and color density checking. Laker support for middle end-of-line (MEOL) layers includes contactless connectivity, unidirectional layer rules and enhancements to support 16-nm guard rings.
Circuit Simulation Performance and Accuracy
Synopsys has optimized the FinFET model used in HSPICE, CustomSim™ and FineSim® for better performance, reduced memory footprint and enhanced multi-threading scalability. The TSMC Modeling Interface (TMI2.0) jointly developed by TSMC and Synopsys enables more accurate layout-dependent effect modeling on top of standard SPICE models.
TMI2.0 also provides a unified infrastructure for statistical modeling, and MOS aging simulation.
IC Validator Signoff Physical Verification for16-nm FinFET
Synopsys has collaborated with TSMC to provide full signoff-accurate runsets for design rule checking (DRC) and layout-vs.-schematic (LVS) checks with TSMC 16-nm V0.5. IC Validator is also integrated into the Laker user environment to allow running DRC and LVS signoff checks and for debugging layout errors with IC Validator's VUE utility.
Electromigration and IR-drop Analysis
Low power design techniques in 16-nm designs require accurate, simulation-based EM/IR analyses. Through close collaboration with TMSC, Synopsys has enhanced its CustomSim EM/IR analysis capability to comply with the new rules for 16-nm designs and support TSMC's iRCX format.
