宝宝宝宝上火便秘怎么办 ocv

# 这两个概念应该好好理解,下面是一些具体的资料,先理解概念,然后再到项目中使用吧,OCV的存在和AOCV的发展,都是为了防止PT的分析过于pessimistic(传统的WCBC分析)
Advanced on-chip variation (AOCV) analysis reduces unnecessary pessimism by taking the design methodology and fabrication process variation into account. AOCV determines derating factors based on metrics of path logic depth and the physical distance traversed by a particular path. A longer path that has more gates tends to have less total variation because the random variations from gate to gate tend to cancel each other out. A path that spans a larger physical distance across the chip tends to have larger systematic variations. AOCV is less pessimistic than a traditional OCV analysis, which relies on constant derating factors that do not take path-specific metrics into account.
The AOCV analysis determines path-depth and location-based bounding box metrics to calculate a context-specific AOCV derating factor to apply to a path, replacing the use of a constant derating factor.
AOCV analysis works with all other PrimeTime features and affects all reporting commands. This solution works in both the Standard Delay Format (SDF)-based and the delay calculation based flows.
PrimeTime ADV parametric on-chip variation (POCV) models the delay of an instance as a function of a variable that is specific to the instance. That is, the instance delay is parameterized as a function of the unique delay variable for the instance. POCV provides the following:
&Statistical single-parameter derating for random variations
&Single input format and characterization source for both AOCV and POCV table data
&Nonstatistical timing reports
&Limited statistical reporting (mean, sigma) for timing paths
&Compatibility with existing PrimeTime functionality, except PrimeTime VX
Compared to AOCV, POCV provides
&Reduced pessimism gap between graph-based analysis and path-based analysis
&Less overhead for incremental timing analysis
# Other comments:
Simply to say,&AOCV&use different derating ocv factor for different stage. In traditional ocv, one constant derating factor is applied to whole chip. But, from statistical analysis, on-chip-variation will be counteracted with stage increasing. So,&AOCV&(stage based ocv) is put to reduce over-design.

  来自岛国科技媒体的最新消息,台湾一线电脑板卡品牌微星,今天隆重面向全球 PC 玩家推出 Geforce GT 1030 2GH LP OCV1 网游刀卡,它跟此前问世的 GeForce GT 1030 AERO ITX 2G OC、GeForce GT 1030 2G LP OCV1、GeForce GT 1030 2GH OC 一样,基于英伟达最新 PASCAL 帕斯卡架构 GP108-300 核心打造,在办公应用、HTML5网页浏览、Photoshop图像处理、高清蓝光4K电影、CS GO之类3D网络游戏等方面都有着十分出色的表现。与目前主流CPU核显相比,微星GeForce GT 1030系列显卡能够提供更流畅的娱乐体验和更高的工作效率,而TDP功耗却仅仅只有30瓦,完全不需要外接供电,非常节能省电,是办公轻娱乐用户不可或缺的优秀装备。  本文主角 GT 1030 2GH LP OCV1 全卡高度只有 69 毫米,是块不折不扣的半高型刀卡,产品定位的缘故,该卡去掉了风扇,只保留覆盖全卡的大型被动散热片来负责给 GPU、供电、显存等部件降温,由于 GP108-300 核心发热不高,即使没有风扇,也不必担心显卡安全,反而可以彻底杜绝显卡风扇带来的噪音干扰,为消费者创造一个极致静音的工作娱乐环境,从而带来出类拔萃的工作效率或享受畅快淋漓的娱乐体验,是那种特别怕吵消费者的不二之选(部分介绍来自微星官网)。   GT 1030 2GH LP OCV1 具备完整的 384 个 CUDA 处理器,GPU 默频 1265MHz、自动超频频率 1518MHz,64 位 GDDR5 2GB 显存频率 6008MHz,利用微星提供的 Afterburner APP 可进一步拉高显卡的工作频率,而为了保障安全超频和长期稳定运行,微星还特意在该卡上运用了军规级固态电容。其它配置方面,显卡使用 PCI-Express3.0 总线接口,随卡提供 HDMI2.0b×1、SingleLink DVI-D×1 头像输出端子,全卡三围 153×69×38 毫米,重 302 克,国内参考售价 599 人民币。=740) window.open('http://img.mydigit.net/Mon_206_1d3b0.jpg?105');" style="max-width:100%;" onload="if(is_ie6&&this.offsetWidth>740)this.width=740;" title="夏天吃烧烤必备!微星隆重发布GT 1030 2GH LP OCV1刀卡" alt="夏天吃烧烤必备!微星隆重发布GT 1030 2GH LP OCV1刀卡">=740) window.open('http://img.mydigit.net/Mon_206_96c074db428b828.jpg?133');" style="max-width:100%;" onload="if(is_ie6&&this.offsetWidth>740)this.width=740;" title="夏天吃烧烤必备!微星隆重发布GT 1030 2GH LP OCV1刀卡" alt="夏天吃烧烤必备!微星隆重发布GT 1030 2GH LP OCV1刀卡">=740) window.open('http://img.mydigit.net/Mon_206_22ede.jpg?85');" style="max-width:100%;" onload="if(is_ie6&&this.offsetWidth>740)this.width=740;" title="夏天吃烧烤必备!微星隆重发布GT 1030 2GH LP OCV1刀卡" alt="夏天吃烧烤必备!微星隆重发布GT 1030 2GH LP OCV1刀卡">[ 此帖被geeker在 15:55重新编辑 ]

没强制散热,热量应该不大吧。
