a practical guide to adopting the universal verification methodology

通用验证方法（Universal Verification Methodology, UVM）是一种用于验证集成电路设计的标准方法。采用UVM可以提高验证效率，降低成本，并增加设计的可靠性。以下是采用UVM的实用指南：

首先，了解UVM的基本概念和原理。UVM是一种基于系统级验证的方法，采用了面向对象的编程技术，并且基于硬件描述语言（HDL）建立。需要对UVM的主要组成部分、工作原理和优势有清晰的认识。

其次，学习UVM的代码结构和规范。了解UVM中的类、对象、接口、事务、测试用例等概念，掌握UVM中使用的基本类和库，并且遵循UVM的最佳实践来编写测试环境和测试用例。

接着，熟悉UVM的建模和仿真技术。掌握UVM中的建模和仿真方法，包括使用事务级建模、驱动、监视器、代理、环境、交易级别的抽象层次（TLM）等技术来建立完整的测试环境。

然后，实践UVM的设计和验证流程。在实际项目中，根据UVM流程的要求，构建测试环境、编写测试用例、执行仿真和调试测试结果，不断优化和改进验证流程。

最后，持续学习和改进。对UVM的采用和实践过程中，及时总结经验，不断学习新的技术和方法，提高验证效率和质量。

总之，采用UVM需要深入理解其原理和规范，掌握相关的技术和工具，不断实践和改进验证流程，这样才能真正发挥UVM的优势，提高验证效率，降低成本，并增加设计的可靠性。

In this paper, we have combined background information with 3D mapping of foregrounds and proposedan occlusion-free model for multiple objects tracking in a complex scenario. As a result, designing a trainedobject detector that does not overlook objects is tough. We can get noisy candidate object locations bysubtracting the background. To get an acceptable quality foreground object, we analyzed and processedeach noisy candidate region. We use the background information model to generate a graph embeddingtracker for each prospective region for localization. Objects that move in a sequential manner arelocalized and their states are updated frame by frame. A basic data relationship between backgroundreference objects and to manage size variations, object fragmentation, occlusions, and lost tracks,background subtraction is used to find targets. Because both graph embedding technique and backgroundremoval could produce errors at numerous times, object states are determined utilizing the informationfrom both. Finally, the system is tested using videos of pedestrians, moving automobiles, and otherobjects from various datasets. The benefits of adopting a robust visual tracker based on backgroundinformation in a MOT framework are demonstrated by simulation results, which demonstrate that ourtechnique is competitive even when data association is minimal.翻译成中文

在本文中，我们将背景信息与前景的3D映射相结合，提出了一种在复杂场景中无遮挡多物体跟踪的模型。因此，设计一个不会忽略物体的训练对象检测器是很困难的。我们可以通过减去背景来获取嘈杂的候选物体位置。为了得到可接受的质量前景物体，我们分析和处理了每个嘈杂的候选区域。我们使用背景信息模型为每个潜在区域生成图嵌入跟踪器以进行定位。按顺序移动的物体被定位，它们的状态逐帧更新。为了管理大小变化、物体分裂、遮挡和丢失跟踪，使用背景减法来查找目标之间的基本数据关系。由于图嵌入技术和背景去除都可能在许多时候产生错误，因此使用两者的信息来确定物体状态。最后，使用来自各种数据集的行人、移动汽车和其他物体的视频对系统进行测试。通过模拟结果展示了采用基于背景信息的强大视觉跟踪器在MOT框架中的优点，即使数据关联很少，我们的技术也是有竞争力的。

Recently, the renowned actor Zhang Songwen has sparked a fascinating phenomenon known as "two-way rejection", which has captured the attention of many and inspired the masses. The roots of this phenomenon are complex, with one of the fundamental causes being the fear of failure that plagues most of us. Rejection can instill a sense of inadequacy and a fear of being perceived as a failure, which can be challenging to overcome. However, the concept of "two-way rejection" teaches us that rejection is a natural part of life, and it's acceptable to reject and be rejected in return. This empowers us to recognize that life is not just about failures, but also about perseverance, and striving to achieve our aspirations, which may include fame and fortune. Despite the distractions we may encounter, the concept of "two-way rejection" reminds us to turn away from erroneous opportunities and remain steadfast in our principles and moral compass. While there are both advantages and drawbacks to this approach, "two-way rejection" ultimately inspires us to embrace rejection, learn from it, and emerge stronger and more self-assured. However, it is essential to distinguish between a sound and an unsound opportunity to avoid blindly rejecting the right ones. In conclusion, the concept of "two-way rejection" should be approached with discretion, but it can prove to be a valuable tool in enabling us to adhere to our goals and persevere through rejection. It teaches us to embrace rejection, learn from it, and move forward with confidence, ultimately empowering us to achieve our dreams and aspirations.结合双向拒绝进行内容补充

The concept of "two-way rejection" is not only about rejecting others but also about being willing to accept rejection ourselves. It encourages us to be open to constructive criticism and feedback, which can help us improve ourselves and our skills. By embracing rejection, we can learn from our mistakes, understand our weaknesses, and work on improving them.

Moreover, "two-way rejection" also emphasizes the importance of communication. It is essential to communicate effectively and honestly with others, whether we are rejecting them or being rejected. We must be respectful and considerate of other people's feelings while also being true to ourselves and our goals.

Another aspect of "two-way rejection" is the idea of resilience. It is about bouncing back from rejection and not letting it define us. When we face rejection, it can be tempting to give up and lose hope, but by embracing "two-way rejection," we can develop resilience and determination to keep pushing forward.

In summary, "two-way rejection" is a powerful concept that can help us overcome the fear of failure and embrace rejection. It encourages us to communicate effectively, be open to feedback, and develop resilience in the face of rejection. By adopting this approach, we can become more self-assured and empowered to achieve our dreams and aspirations.
