Hamamatsu Photonics has adopted Siemens’ mPower digital software for the power integrity analysis of its next generation of optical semiconductor devices. Introduced last year, mPower helps users perform quick and accurate signoff analysis of the power, electromigration, and IR-drop performance of integrated circuits, helping them to confirm that their design will meet performance and reliability targets when manufactured. The solution supports analysis across the integrated circuit (IC) design process, from initial concept design to design signoff, helping users to create more efficient designs with no compromise in quality or speed. According to Joe Davis, senior director for Interfaces and EM/IR Product Management for Siemens EDA, as image sensors grow in size and complexity, it becomes more difficult — as well as more critical — to verify the power integrity of the (very large) designs of the sensors. Masaaki Matsubara, manager for the Design Center, Solid State Division for Hamamatsu Photonics, said, "Power integrity analysis is a critical technology for us, because our optical IC products need to achieve extremely high performance and reliability in order to meet stringent functionality requirements. "We believe Siemens’ mPower digital software is our best option for improving IC performance and reliability. Our designers use the mPower solution to analyze their designs at early stages of development, and the software definitely helps to optimize the power source design faster," Matsubara said.
