vivado中design runs中WNS

WNS是“Worst Negative Slack”的缩写，代表设计中最差的负时序裕量。在Vivado中，“Design Runs”是一个流程，用于执行综合、实现和生成比特流等操作，以生成可编程逻辑设备（PLD）的bit文件。WNS是在实现过程中生成的一项报告，它给出了设计中最差的负时序裕量，即设计中存在的最紧迫的时序问题。WNS值越小，表示设计越难以达到时序要求，需要进行更多的时序优化。

vivado block design

Vivado Block Design is a graphical design tool that allows designers to create complex digital designs using pre-defined blocks, also known as Intellectual Property (IP) blocks. These blocks can be combined together to create a complete system design.

Vivado Block Design provides an intuitive interface to add, remove, and connect different IP blocks to create a system design. It also allows designers to define interconnects and constraints without having to manually write code.

With Vivado Block Design, designers can create, import, and export IP blocks, as well as simulate and test their designs using the built-in simulator or external simulators.

Some of the benefits of using Vivado Block Design include faster design iterations, reduced design complexity, and improved design productivity.
