Lyric™

Lyric combines interactive and semi-automated layout editing with shape-based auto-routing.

Intelligent interactive editing

Achieve fast accurate layout with an interactive editing environment that’s ideal for all types of IC design. Lyric Editor provides a single, highly intuitive environment that enables you to adjust cell placement and edit circuit interconnects with ease to achieve significant productivity gains. A comprehensive shape editing suite is complemented by connectivity-driven tools that generate DRC correct layouts as well as ‘change layer’ and ‘change width’ features. Extensive operation reports and checks ensure full design-for-manufacture adherence.

• Easy-to-use intuitive environment.
• Connectivity-driven (automatic) interactive editing, with manual mode if required.
• Unique ‘push and shove’ feature supports fast space creation/compaction in the layout.
• Shape-editing functionality incorporates data entry, routing and shape manipulation through to merging, breaking and slotting.
• Unlimited undo/re-do capability.
• Automatic and interactive bus routing.
• DFM specific layout capabilities and checking, including density and slotting routing.

Shape-based auto routing

Lyric Router gives you the highest quality-controlled and constrained automatic routing system available on the market today. Designed to rapidly accommodate the very latest and toughest nanometer processes and rules, yield improvement is a key capability of the tool. Lyric Router simultaneously handles minimum/optimum rules and contains an optimisation programme to identify and improve yield unfriendly layout shapes. A hierarchical constraint management system supports constraint implementation from other front-end tools, such as Cadence schematics.

• Full topology and routing control.
• Full automatic routing, current density-driven routing, footprint routing, mirror routing and mirror routing from a template.
• Rip-up and re-route ‘cleaning’ features (including higher percentage of optimal widths/spacing, on-grid routing, metal-wire, utilisation and user-specific criteria).
• Supports nm process rules (for example, end-of-line, fat wire).
• Comprehensive optimal via support (for example, number size and orientation).
• Support for DFM ― slotting and density routing and checks.

Global routing

A powerful high-speed global routing engine works in conjunction with the detailed routing engine to vastly speed-up the detailed routing phase. All embracing pre-detailed route analysis enables you to meet key constraints, including timing.

• Delivers graphical usage and congestion analysis.
• Inbuilt RC extraction engine.
