Synopsys DesignWare IP Solution
  • Achieved low power consumption goals
  • Reduced integration risk with silicon-proven IP
  • Collaborated successfully with experienced technical support team to accelerate and ease the integration process

Fujitsu Semiconductor’s customer needed to launch its own mobile platform quickly with low-power 28nm 2G/3G/4G baseband product supporting multimode, multiband LTE, UMTS, and EDGE mobile handsets with full support for all global FDD and TDD bands. To achieve the shortest time to market after receiving the first engineering samples, interoperability between DigRF interface on baseband side and RFIC was one of the most critical parts.

“Our customer’s next-generation mobile devices required low-power, high-bandwidth connectivity, so we needed a reliable IP solution that is compliant to MIPI standard specification, in the required process technology,” said Daisuke Yamazaki, Manager, Design Department, Wireless Solution Division at Fujitsu Semiconductor. “We selected Synopsys’ DesignWare DigRFv4 M-PHY and DigRF 3G PHY IP, which are designed to provide mobile devices targeting 4G speeds with high data rates and low power consumption.”

High-Quality DesignWare IP
Fujitsu Semiconductor knew that reliable IP was imperative to the time to market of their customer’s products in such a rapidly changing market. In addition, the DigRFv4 and DigRF 3G standard specifications required fine tuning, so Fujitsu Semiconductor needed a dependable IP provider with whom they could work to identify and address conflicts between the standards. Fujitsu Semiconductor found that Synopsys and its low power MIPI DigRFv4 M-PHY and DigRF 3G PHY met both of these requirements.

While Fujitsu Semiconductor has the capability to develop complex IP internally, they chose to use Synopsys DesignWare IP so that they could focus on providing custom ASIC services in a timely manner. Using Synopsys IP allowed Fujitsu Semiconductor to focus its resource allocation and shorten their overall product development period. Integrating DesignWare IP allowed Fujitsu Semiconductor deliver an efficient, low-power, and cost-effective solution for this demanding mobile device application.

Expert and Responsive Support
Fujitsu Semiconductor worked closely with Synopsys technical support engineers throughout their development and integration process. As both the specific process technology and the standard specification were being finalized in parallel with the IP integration, clear and consistent communication between Synopsys and Fujitsu Semiconductor was required for successful product development.

“We were pleased with Synopsys’ responsive and expert technical support,” said Daisuke Yamazaki, Manager, Design Department, Wireless Solution Division at Fujitsu Semiconductor. “We plan to integrate DesignWare IP into future projects as we have every confidence that Synopsys will continue to meet our design and support requirements.”
