怎么在Vivado 2015.3中创建一个库

您好，我正在为Vivado 2015.3课程做一个项目。
该项目是边界扫描测试。
我编写了所有VHDL代码并尝试实现。
但是，实施还没有发生。
我一直得到错误：[Synth 8-4169]使用条款中的错误：库'work'中找不到包'tap'[Synth 8-1031]未声明tap_state [Common 17-69]命令失败：合成失败
- 请查看控制台或运行日志文件以获取详细信息因此，我正在搜索相关问题的论坛，我遇到了另一个遇到相同问题的帖子。
在该帖子中，创建库将有助于绕过此问题。
我一直在尝试创建一个库并在其中添加包，但我没有成功。
那么，请指导我创建一个库以及如何在其中包含软件包.P.S：使用Xilinx ISE编译和创建相同的VHDL代码，但对于vivado，我遇到了酸味。谢谢！

Hello,

I am doing a project for my course in Vivado 2015.3. The project is Boundary scan test. I have written all the VHDL code and tried to implement. But, the implementation has not been happening. I have been getting errors as:
[Synth 8-4169] error in use clause: package 'tap' not found in library 'work'
[Synth 8-1031] tap_state is not declared
[Common 17-69] Command failed: Synthesis failed - please see the console or run log file for details

So, I was searching for forums for relatable issue, I came across with another post who experienced the same issue. In that post, creating a library would help to bypass this issue. I have been trying to creating a library and adding packages into it, but I am not succeeding. So, please guide me in creating a library and how to include packages in that.

P.S : The same VHDL code compiled and impelmented using Xilinx ISE, but for vivado, I am experiencing sour taste.

Thank you!
