Chisel 3 中运行 "sbt test" 之后的错误

Question

我正在尝试使用凿子 3。

我尝试在回答上一个问题后使用 sbt test 和 sbt "test-only example.GCD" 命令测试 chisel 项目模板回购中的 GCD.scala 文件。但这给出了一个我找不到原因的错误。我没有对 build.sbt 文件或存储库布局进行任何更改。我只发布错误消息的最后一部分，因为它很长且重复。

Answer 1

您显示的错误表明 sbt 不知何故找不到 Chisel，您能否偶然显示完整的错误列表（尤其是早期的错误）？使用以下命令序列，我无法重现您看到的错误：

git clone git@github.com:ucb-bar/chisel-template.git    
cd chisel-template    
sbt test

这不是这个问题的原因，但运行在 chisel-template 中的测试你实际上应该运行 sbt "test-only examples.test.GCDTester"。 example.GCD是顶层的设计，但是要运行测试就得参考src/test/scala/examples/test/GCDUnitTest.scala中的Tester class.

Answer 2

我在制作自己的凿子项目时遇到了同样的问题。然而，这并不是说 import chisel3._ 是错误的。我遇到的问题是我的目录中没有 build.sbt 文件。
