Olympus: Product Highlights

Olympus-SoC is architected specifically to solve the unique challenges of 65nm, 45nm, and smaller process geometries. Product/technology highlights include:

Litho Driven Routing

A fully featured, multi-CPU detailed routing engine built from the ground-up to address complex 65nm DRC rules and litho-errors. Unlike the pure gridded or pure gridless routing methods of traditional routing solutions, Olympus-SoC’s “hybrid” approach provides the speed of gridded routers with the accuracy of gridless approaches. Olympus-SoC includes a shape-based multi-CPU DRC engine that evaluates complex shape-based DRCs during routing to produce inherently more litho-friendly designs. Layout enhancement capabilities include wire spreading, redundant via insertion, jog-widening and timing driven metal fill. Olympus-SoC also supports Critical Area Analysis to account for random process variations.

Unique OptRoute Technology

The OptRoute engine enables “live” interaction between route-based variability optimization and detailed routing to ensure that variability and routing engines are constantly in-sync with the changes being made to the design. Both engines are linked to the embedded variation-aware timing engine to achieve timing closure across all modes and corners during routing.

Powerful ECO Routing

Multi-CPU ECO routing is integrated with post-route optimization to achieve rapid timing closure. The Olympus-SoC router makes changes to the layout to correct lithography hot-spots and litho-unfriendly structures. Enhancements such as wire-widening and local re-routing are done without affecting the overall timing performance or introducing OCV-related hold violations.

Sign-off Quality Timer

The embedded, signoff variation-aware timing engine drives the router and optimization engine to achieve automatic timing closure across all modes and corners while routing. The analysis engines also support modeling for metal thickness variation due to CMP (Chemical Mechanical Polishing).
