GN ReSound adopts Magma Talus for hearing solutions

According to Magma Design Automation, hearing instrument solution maker GN ReSound has selected the Talus implementation system for its next-generation ICs. GN ReSound is said to have chosen Talus after coming across difficulty in closing timing while meeting low-power requirements on a critical design with its previous tools. On the other hand, Talus gave a fast, predictable and repeatable flow which enabled GN ReSound to rapidly perform trial place-and-route runs to find the optimal power/performance tradeoff.

Director of HWP Electronics Research & Development at GN ReSound, Dr. Lars J. Stenberg says, "Minimizing power consumption to prolong battery life is extremely critical in hearing instruments, and performance and time to market are also important." He cites, "Talus delivers consistent timing throughout the flow, even during routing, which means we don't waste time solving timing divergence problems or have to reduce chip functionality or performance, and can still achieve the low-power goals of our next-generation ICs."

Meanwhile, general manager of Magma's design implementation business unit, Premal Buch stressed, "Unlike other implementation tools, Talus performs continuous power, timing and area tradeoffs throughout the design flow."

Magma explained that the ability to customize the standard Talus flow was likewise important in achieving minimal power. First, the clock tree synthesis was customized to drive a low-power, low-area clock tree (a specific goal for the clock tree was to make the buffer count as low as possible to reduce area). Second, the optimization, as well as clock gating, was then customized to be managed by switching activity to get the lowest power.
