关于客户
富士通微电子有限公司是计算机和通信设备微电子领域的全球领导者。该公司一直处于开发新技术的前沿,以满足由于多媒体产品和消费者需求的进步而不断增长的移动电话带宽需求。在过去五年中,富士通在制定全球微波接入互操作性 (WiMAX) 新标准方面发挥了重要作用。该公司已成功开发出首款用于移动 WiMAX 应用的 65nm SoC,这是一款完全集成的 MAC 和 PHY 混合信号基带处理器,旨在支持授权和非授权频段的 2 至 11GHz 频率。
挑战
富士通微电子有限公司是计算机和通信设备微电子领域的全球领导者,面临着通过减小芯片尺寸和功耗要求使移动 WiMAX 成为现实的挑战。实现这一目标的关键是优化电源设计,以尽可能降低总体使用率和关断泄漏。以前,在设计过程的每个阶段做出的独立决策常常会以不可预见的方式影响其他领域,从而对最终的功率特性产生不利影响。由于需要将 CPF 周围的电源设计与精确的仿真保持一致、转向更小的几何形状、缩短设计时间并提高硅的质量,这一挑战进一步加剧。
解决方案
富士通采用了更加统一的电源设计方法,从设计过程一开始就应用参考规范,以推动跨工程专业的优化。这种方法是通过支持通用功耗格式 (CPF) 的 Cadence® 低功耗方法实现的,该方法已成为低功耗、亚微米片上系统 (SoC) 设计的参考设计流程 (RDF) 机制的组成部分。富士通于2007年为WiMAX项目开发了自己的基于CPF的RDF概念。对于该项目的主要设计流程,富士通选择了Cadence低功耗解决方案,该解决方案为设计、验证提供了完整的从前到后的低功耗功能和实施。 Fujitsu RDF 实施是围绕 Cadence 平台构建的,以确保顺利集成和数据切换。许多 CPF 创新也被纳入低功耗解决方案和 Cadence Encounter® 数字实现系统中,为支持 CPF 的低功耗设计创建了最先进的统包平台。

Hydro One Leads the Way In Smart Meter Development
In 2010, Ontario’s energy board mandated that time-of-use (TOU) pricing for consumers be available for all consumers on a regulated price plan. To meet this requirement, Hydro One needed to quickly deploy a smart meter and intelligent communications network solution to meet the provincial government’s requirement at a low cost. The network needed to cover Hydro One’s expansive service territory, which has a land mass twice the size of Texas, and its customers live in a mix of urban, rural, and remote areas, some places only accessible by air, rail, boat or snowmobile. Most importantly, the network needed to enable future enterprise-wide business efficiencies, modernization of distribution infrastructure and enhanced customer service. To meet these needs, Hydro One conceptualized an end-to-end solution leveraging open standards and Internet Protocols (IP) at all communication levels. The utility drew upon industry leaders like Trilliant to realize this vision.

Selling more with Whirlpool
Whirlpool wanted to add connectivity to appliances and transform the company's relationship with customers. Traditionally, Whirlpool interaction with customers was limited to purchases made once every ten years. Connected washer and dryers provide exciting new features like remote management of start times and inter-machine communication.

SAS® Analytics for IoT: Smart Grid
Companies face falling revenues, rising infrastructure costs, and increasing risk of outages caused by inconsistent energy production from renewable sources. Less money is coming in as more people and organizations take steps to curb their energy use. Utilities are paying more to maintain and build infrastructure due to increasing complexity, resulting from the rising number of intermittent and variable renewable energy sources connected in the distribution grid.

Enel Secures Italian Power Generation Network
Electric energy operators around the world are working to increase the reliability and cyber resiliency of their systems. This includes Enel, a global power company that manages and monitors the Italian power grid. This grid:• Serves 31 million customers• Has a net installed energy capacity exceeding 31 gigawatts• Includes more than 500 power generation plants,including hydroelectric, thermoelectric, and wind• Is managed and monitored by Enel 24/7/365• Is operated by Terna, the Italian Transmission System Operator (TSO)Enel is responsible for the availability of the grid’s underlying ICS and industrial network. It also manages Regional Control Centers and Interconnection Centers which connect with the TSO. The TSO manages the flow of energy to the grid plus controls and remotely regulates the power generation of power plants, increasing and decreasing power production as required. The complex system of interaction and cooperation between Enel and the TSO has strong security implications as well as operational and business challenges.

Vodafone Hosted On AWS
Vodafone found that traffic for the applications peak during the four-month period when the international cricket season is at its height in Australia. During the 2011/2012 cricket season, 700,000 consumers downloaded the Cricket Live Australia application. Vodafone needed to be able to meet customer demand, but didn’t want to invest in additional resources that would be underutilized during cricket’s off-season.
