Cadence Design Systems Inc. has introduced the Cadence Precision Router, a space-based, full-chip and block routing solution for advanced mixed-signal, analog and custom digital designs. According to the company, the product speeds design and manufacturing convergence by allowing designers to model manufacturing effects during the design process for design performance closure and faster time-to-volume manufacturing ramp-up.

Complex interconnect rules, including those at 65- and 45nm, challenge the physical modeling capability of traditional shape-based and gridded routers. The new routing solution uses a three-dimensional, space-based modeling approach to analyze true shapes and intervening physical spaces to handle the complexity inherent in ever-increasing design sizes and shrinking process geometries. This product provides greater accuracy, precision and flexibility than shape-based approaches in creating, checking and manipulating interconnects, and minimizes the steps to design and manufacturing convergence, Cadence said.

The Cadence Precision Router, along with Cadence Chip Optimizer, is built on innovative technology developed in the company's Project Catena technology incubator and can be applied to a broad range of design styles and process nodes.

"Process variability, increasingly complex design rules and manufacturing effects from lithography and chemical mechanical polishing (CMP) are becoming first-order effects," said Ted Vucurevich, CTO of advanced research and development at Cadence. "To tackle these issues, we've developed an entirely new architectural approach for Cadence Precision Router where physical, electrical, and logical perspectives can be presented to the designer all at once. This approach is the cornerstone of convergence and paves the way for designers to achieve the superior quality of results, high capacity and increased throughput needed for routing tomorrow's most advanced designs."

Cadence Precision Router is part of Cadence's growing family of design and manufacturing closure technologies that help designers address both design performance and manufacturing and yield issues throughout the design flow. The new device is an OpenAccess-based application that works seamlessly with the Virtuoso custom design platform and is complementary to the Encounter digital IC design platform.
