UniRoute™

UniRoute is a fully featured shape-based automatic routing system that’s capable of supporting the most complex design rule sets and advanced node technologies. It is continuously updated to accommodate the latest advanced node processes and design rules for fabless and IDM semiconductor customers.
UniRoute supports industry standard interfaces and formats including the Si2 OpenAccess database, cdba/DFII, LEF/DEF, Verilog and Spice.

As a product of Unity™, UniRoute is fully integrated with hierarchical floorplanning, placement, editing, timing and signal integrity components ― a single mouse click enables you to move between individual components with ease.

• Full automatic routing
• Footprint routing.
• Footprint, mirror routing and mirror routing from a template.
• Full topology and routing control.
• DFM routing (slot/density check and filling/comprehensive check and reporting).
• Routing – net tapering (changes track width based on pin current attributes)
• Support for process rules (e.g. end of line/fat wire).
• Current density driven routing.
• Rip-up and reroute ‘cleaning’ features including higher percentage of optimal widths/spacing, metal-wire utilisation and user-specific criteria.
• Automatic cleaning and removal of intra-net.

Yield improvement

UniRoute contains an program to identify and improve unfriendly layout shapes. Fully constraint driven ― with a hierarchical constraint management system ― constraints can be passed from other front-end tools, such as Cadence schematics.

• Simultaneous management of optimal spacing and minimum spacing.
• Comprehensive optimal via support (number size/orientation).
• Support for DF (slotting and density routing and checks).
• Graphical usage and congestion analysis.
• Built-in RC extraction engine.
