Synopsys' Design Compiler Graphical Shortens Design Schedule at Oticon
Early Removal of Routing Congestion Essential to Meeting Time-to-Market and Area Goals for Next Generation Hearing-Aid DSP Chipset
"We strive to deliver innovative hearing-aids to our customers, and minimizing the size and power consumption of these devices is critical to our success," said Mogens Balsby, director of Silicon Engines at Oticon. "As we enhanced the feature-set of our next-generation DSP, we saw severe routing congestion due to tight chip area requirements. By utilizing Design Compiler Graphical's congestion optimizations, we eliminated this routing congestion upfront without having to increase our chip area, and taped out successfully ahead of schedule."
Design Compiler Graphical extends DC Ultra(TM) topographical technology to predict routing congestion "hot spots" early in the design flow, providing designers with visualization of congested circuit regions and performing specialized synthesis optimizations to minimize congestion in these areas. This enables RTL designers to avoid wire-routing congestion problems that occur during detailed routing and eliminate costly design iterations.
Additionally, Design Compiler Graphical provides access to IC Compiler's design planning capabilities from within the synthesis environment, giving RTL designers the ability to explore and converge on an optimal floorplan faster. It also produces physical guidance to IC Compiler physical implementation, tightening timing and area correlation to 5 percent while speeding-up IC Compiler placement by 1.5X. By enabling RTL designers to achieve an optimal floorplan efficiently and passing physical guidance to IC Compiler, Design Compiler Graphical can double the productivity of the entire synthesis and place-and-route flow.
"Shorter, more predictable design schedules help our customers bring competitive products to market faster," said Antun Domic, senior vice president and general manager of Synopsys' Implementation Group. "Synopsys continues to deliver innovative RTL synthesis technologies, such as congestion optimization, floorplan exploration and physical guidance to IC Compiler, enabling companies like Oticon to meet their challenging design and time-to-market goals."
