关于客户
威盛电信是一家领先的无晶圆厂半导体公司,专门开发用于移动应用的低功耗码分多址 (CDMA) 基带处理器。该公司最新的单芯片CDMA基带处理器支持一系列双模技术,包括CDMA2000、1xEVDO和CDMA2000/GSM。为了支持其全球手机制造商客户群,威盛电信在世界各地设有国际设计中心。基于该公司处理器的手机已出现在全球 20 多个国家的产品中。 Frank Hsu 是该公司的 ASIC 设计经理,负责监督向后端团队提供网表的方法,以及时序收敛和生产测试流程。
挑战
威盛电信是一家领先的无晶圆厂半导体公司,在竞争激烈的市场中提供低功耗基带处理器时面临着重大挑战。该公司的客户(主要是手机制造商)面临着越来越大的压力,要求他们提供低功耗和长电池寿命的独特移动设备。由于上市时间的需求,这些客户还面临着设计周期缩短的问题。为了跟上客户的步伐,威盛电信需要放弃手动流程来验证其数字基带处理器设计的功耗意图。该公司正在寻求一种经过验证的解决方案,并提供强有力的支持,以实现该流程的自动化并保持低功耗,同时确保及时交付产品。
解决方案
VIA Telecom 向 Cadence 寻求解决方案。该公司实施了 Cadence Encounter Conformal Low Power,使工程师能够在其设计环境中创建和验证功耗意图。该工具将低功耗等效检查与结构和功能检查相结合,从而实现节能设计的全芯片验证。威盛电信还使用 Cadence Encounter 数字实现系统对其设计进行物理实现,并使用 Cadence Encounter RTL 编译器进行自上而下的全局寄存器传输级 (RTL) 设计综合。此外,该公司还使用 Cadence Incisive Enterprise Simulator 来创建自动化测试平台、低功耗和指标驱动的验证以及混合信号验证。当地 Cadence 应用工程师的支持帮助团队顺利、高效地将新流程融入到他们的遗留流程中。

Case Study
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.
