Characterization tools reduce power by ten percent for mobile applications
In addition, the Cadence characterization solution, which comprises the Virtuoso Liberate and Spectre products, provided a 2x speedup in turnaround time for characterization when compared to Yamaha’s previous technology. The benefits translate to better power performance in chips that get to market faster.
“Cadence offered the only solution capable of characterizing our complex multi-bit cells,” said Shuhei Ito, development director, semiconductor division at Yamaha. “The Virtuoso Liberate and Spectre tools were critical in helping us develop our new low-power solution and in meeting our time to market goals.”
“Yamaha’s previous technology was unable to characterize the complex multi-bit flip-flop cells required for the low-power flow Yamaha adopted,” said Dr. Chi-Ping Hsu, senior vice president, Silicon Realization Group at Cadence. “With its patented ‘Inside View’ technology, the Virtuoso Liberate tools enabled Yamaha to characterize these cells automatically by eliminating the need for the user to define the functional description of the cell or specify worst-case conditions. The Cadence characterization solution meets the ease-of-use, throughput and accuracy requirements that has helped Yamaha engineers reduce power for mobile applications while cutting characterization runtimes in half.”
