我没有指定(标记为目标)约束文件作为设计事件的约束

标签: keyboard vhdl vivado

我有一个学校项目,需要使用Vivado 2018.3在USB HID键盘和VHDL中的Nexys4DDR之间创建通信。我使用了here中的Nexys 4键盘演示,该演示是用VHDL编写的,并在其中添加了DCD以解码值并输出正确的字母。我的问题是位流生成。我得到的错误仅在运行位流生成时出现,并且没有出现在综合或实现中。

  

警告:[约束18-5210]未选择写约束。   解决:此消息可能表明没有设计约束,或者可能表明已设置used_in标志,从而忽略了约束。在运行synth_design时,不将综合约束写入结果检查点时将使用后一种情况。而是在打开综合设计时读取项目约束。

我使用了与程序中从勤奋指定的约束文件相同的约束文件。 我不确定问题出在哪里。

我的约束文件是:

## Clock signal

是否有人遇到了这个问题并有解决方案?

谢谢!

1 个答案:

答案 0 :(得分:1)

不确定这是否有帮助,但是我有一个类似的设置(Vivado 2019.2和Nexys 4(不是DDR)。我有一个非常相似的问题;我无法生成位流。仔细检查表明,此后我也有此错误综合:对我有用的是此解决方案,该解决方案由hongh用户在此处发布:Here

使用以下方法生成synth.dcp时,警告 消失并且没有任何约束缺失:

<1>。开放式综合设计

<2>。 write_checkpoint synth.dcp (在TCL控制台中键入该命令)

完成这两个简单的步骤之后,我能够运行Implementation并成功生成位流,并且可以对板进行编程。希望对您有所帮助,并祝您项目顺利!
