系统感知型SoC的功耗、噪声和可靠性验收

在全球竞争激烈的移动、消费类和汽车电子系统市场中,低功耗、高性能以及高可靠性是至关重要的成功因素。为了应对这些相互冲突的要求,设计团队需要面面俱到地考虑多种方案,例如采用高级工艺技术节点,尤其是基于FinFET的器件。这些高级技术节点让芯片不仅能在更低功耗下以更快的速度运行,同时还可在相同尺寸的硅片中集成更多功能。但是,在这些工艺节点上,由于器件的物理特性、尺寸和形状以及互联等因素,在进行功耗、噪声和可靠性验收时会遇到严重问题。

低功耗设计方法助力尽早实现功耗收敛

商用功耗分析工具推出已十年有余,主要应用在门级和晶体管级的抽象层面上。对模拟、混合信号和定制设计来说,晶体管级的工具既可当作设计工具使用,也可当作验证工具使用。它们可帮助设计人员分析功耗,并能作为最终“验收”工具使用,以确保满足功耗规格。在综合驱动的基于标准单元的ASIC和SoC设计上,门级和晶体管级功耗分析工具一般都作为最终验证工具使用。如果在验证过程中发现有要求重新综合设计的强制性设计修改,那么就需要进入广泛的验证阶段了。由于在流程中需要使用多种工具进行多次迭代,这样就会导致更长的设计收敛时间。本白皮书将介绍一种低功耗设计(DFP)方法,它从设计流程的寄存器传输级(RTL)阶段开始,旨在满足设计的功耗预算以及设计收敛时间和产品上市时间的要求。

Dedication of Commercial Grade Design and Analysis Software - White Paper

"Until recently, quality processes known as software verification and validation were typically used as qualification of commercial grade software in many software quality assurance programs. Many believed that commercial grade dedication was not an option for complex items such as computer programs. Although discussed in terms of plant structures, systems, and components in 10CFR21, the Nuclear Regulatory Commission (NRC) concluded that design and analysis software could meet the definition of a commercial grade item in the U.S. NRC Safety Evaluation Report (SER) of Topical Report.

In this report, the NRC noted that existing software quality assurance practices that rely on verification and validation alone may not be sufficient to accept commercial grade computer programs for use in safety-related applications. The NRC emphasized that commercially produced computer programs used for safety-related design and analysis are considered to be safety-related, and safety-related items must be either designed and manufactured in accordance with a quality assurance program that meets the requirements of Appendix B to 10CFR50, or dedicated for use in a safety-related"

A Methodology for Comprehensive and Productive Power Noise and Reliability Closure for Advanced SoC Designs - White Paper

One of the key technology trends driving the semiconductor industry is the adoption of FinFET processes. As opposed to a traditional planar transistor, the FinFET has an elevated channel or 'fin', which the gate wraps around. Due to their structure, FinFETs consume much lower leakage power and allow greater device density. Compared to planar transistors, FinFETs operate at a lower voltage and offer higher drive current. All of these properties lead to lower circuit delay, lower leakage and higher performance packed into a smaller area. This also means that FinFETs offer reduced cost per unit performance. Designing a complex SoC using advanced FinFET-based technologies for first pass silicon success requires proven tools and methodology.

Chip-Package Co-analysis Using ANSYS RedHawk-CPA - White Paper

ANSYS RedHawk-CPA is an integrated chip–package co-analysis solution that enables quick and accurate modeling of the package layout for inclusion in on-chip power integrity simulations using ANSYS RedHawk. With RedHawk-CPA a designer can perform static IR drop analysis and AC hotspot analysis of the package layout following RedHawk static and dynamic analyses respectively. To ensure a reliable supply of power, and stable voltage levels at the transistor connection points, the entire system power delivery network (PDN) must be optimized and validated, including the impact of package on a chip.

System-Aware SoC Power, Noise and Reliability Sign-off - White Paper

In globally competitive markets for mobile, consumer and automotive electronic systems, the critical success factors are power consumption, performance and reliability. To manage these conflicting requirements, design teams consider multiple options, including the use of advanced process technology nodes — especially FinFET-based devices. These advanced technology nodes allow chips to operate faster at lower power and to pack more functionality within the same size of silicon. In these process nodes, however, power, noise and reliability sign-off create significant problems arising out of the physics, size and shape of the devices and interconnects.
