Newport Media Adopts Azuro’s Clock Tree Solution

Azuro, Inc. the provider of advanced clock implementation tools for nanometer chip design, today announced that Newport Media Inc., a developer of highly integrated solutions for digital audio and mobile TV broadcast standards, has adopted Azuro’s PowerCentric™ product for clock implementation on all their integrated circuit (IC) designs at 65nm and below.

“It typically took us several days and three or more manual iterations to get the clock right,” said Darren Woodhouse, physical design manager at Newport Media. “With Azuro we are able to run a one-step automatic script that produces a much better clock result in about one hour.”

As leading edge systems-on-chip (SoCs) incorporate more functionality and strive to minimize power, the number of clocks increases and the balancing constraints become very complex. Azuro’s advanced clock tree synthesis (CTS) technology has helped Newport Media achieve timing closure more quickly by shortening the clock insertion delay and by reducing the clock skew across multiple timing corners and operating conditions. In addition, the more efficient clock structure significantly lowers the clock power and reduces the clock cell area.

“We are experiencing a sharp increase in the number and complexity of clocks as the designs move to smaller geometries,” said Paul Cunningham, co-founder and chief executive officer for Azuro. “Without significant investments in new methodologies, clock implementation will become a bottleneck for the semiconductor industry’s ability to utilize the latest technology.”
