uvm中transaction作用

In the Universal Verification Methodology (UVM), a transaction denotes a structured data entity utilized for representing an individual unit of activity within a design or testbench. Such transactions are instrumental in modeling the interaction between distinctponents of the design, including the dynamic interplay between the Design Under Test (DUT) and the testbench environment. Within the framework of UVM, transactions are typically concretized as classes, with each class embodying a specific category of transaction. For instance, a transaction class may be delineated to signify a memory read or write operation, a bus transaction, or a data packet transmission between twoponents. Subsequently, transactions may encapsulate fields and methods to embody diverse properties and behaviors inherent to the transaction, epassing attributes such as address, data, control signals, and timing information.
在通用核查方法（UVM）中，交易是指用于代表设计或试验台内单个活动单位的结构化数据实体。

这种交易有助于模拟设计的不同主体之间的相互作用，包括测试下设计（DUT）与测试台环境之间的动态相互作用。

在UVM框架内，交易通常被具体化为类别，每个类别都包含特定类别的交易。

可划定交易类别，以表示内存读写操作、总线交易或两单体之间的数据包传输。

随后，交易可以封装字段和方法，以体现交易固有的不同属性和行为，传递位置区域，数据，控制信号，
计时信息等属性。

One great thing about using transactions in UVM is that they give us a simpler way to show how various parts of a design talk to each other. This makes it easier to build testbenches that can be used over and over again, because we can define transactions separately from the specific tests we want to run. With transactions, we can switch up our tests without having to change how everythingmunicates. Plus, using transactions helps us make our testbenches more efficient and tidy, since we can make reusable parts and libraries that we can use in lots of different tests and projects. This can really save us time and make our verification setups easier to manage and expand.
使用UVM交易的一个伟大之处是，它们给了我们一个更简单的方法
来显示设计的各个部分如何相互交谈。

这使得建立可以反复使用的睾
丸更容易，因为我们可以将交易与我们希望运行的特定测试分开定义。

通过交易，我们可以切换我们的测试，而不必改变一切免疫。

使用
交易可以帮助我们提高测试机的效率与整洁性，因为我们可以做一些
可以重复使用的部件和库，用于很多不同的测试和项目。

这确实可以
节省我们的时间，使我们的核查机构更容易管理和扩大。

In essence, transactions within the Universal Verification
Methodology (UVM) serve as a vital conduit for facilitating seamlessmunication and interaction among the variousponents within a design or testbench. They epass a high-level, abstract depiction of the data and control signals being exchanged, thereby fostering a modular, reusable, and efficacious testbench architecture. Embracing the utilization of transactions empowers verification engineers to construct more scalable and sustainable testbenches, thereby culminating in elevated levels of productivity and quality within their verification endeavors. This aligns with our overarching pursuit of advancing robust and efficient methodologies for verification practices in the realm of electronic design automation.
从本质上讲，通用核查方法范围内的交易是便利各主管机构在设计或试验台内无缝免疫和互动的重要渠道。

它们通过高层次、抽象地描述正在交换的数据和控制信号，从而形成一个模块化、可重复使用和有效的测试台架构。

利用交易使核查工程师能够建造更可扩展和更可持续的试管，从而最终在其核查工作中提高生产力和质量。

这与我们在电子设计自动化领域推动可靠和高效率的核查做法的总体追求是一致的。
