By Hans Lewis TMCnet Contributor Azuro has announced version 1.4 of Rubix, the company’s industry-leading clock concurrent optimization tool. Azuro is the provider of advanced clock and timing optimization tools for digital chip design. This release deploys extensive refinements to the product’s underlying timing-driven placement, logic sizing, and useful skew-based clock tree synthesis algorithms, resulting in an average 15 percent increase in clock frequencies beyond traditional skew-balanced flows, 5 percent higher than the previous version of Rubix. The product also includes full support for version 1.1 of the Common Power Format (CPF). In a release, Paul Cunningham, CEO of Azuro, said “Rubix continues to build momentum within our existing customer base and also through several new customer engagements. At 40 and 28nm, building clocks to deliver the best timing rather than to be skew balanced is becoming a must-have to meet schedules and manage power consumption. With this new release of Rubix we are seeing yet further improvements in our already significant clock speed gains, even on high performance CPUs and GPUs. These improvements typically come with impressive 10 to 30 percent reductions in leakage power as well.” Clock concurrent optimization is a new approach to clock tree synthesis which builds useful skew-based clocks concurrently with performing logic gate sizing and placement. The key defining characteristic of clock concurrent optimization is that the timing picture being considered by all its underlying algorithms is a true “propagated clocks” view of timing based on real propagation of clock signals through the clock network.
