Scala 在zed板上运行虚拟试验

dummy_rocc_测试在带有custom0指令的spike上运行良好，但是当我将它放在zed板上并使用

/fesvr zynq pk dummy_rocc_测试运行时，它给了我一个非法指令的错误

我理解这是因为rocc io不是但在火箭芯片的默认配置中，但我想知道如何启用rocc接口，以便在zed板上运行虚拟roc测试。我尝试将下面列出的值赋给“BuildRoCC”，如代码段所示

case BuildRoCC => Some(() => (Module(new AccumulatorExample, { case CoreName => "rocket" })))

但在制作火箭时，我得到以下错误：

[error] /home/prashantravi/rocket-chip/src/main/scala/Configs.scala:100: could not find implicit value for parameter p: cde.Parameters
[error]       case BuildRoCC => Some(() => (Module(new AccumulatorExample, { case CoreName => "rocket" })))

最好查看
Configs.scala
的完整源代码，但似乎
Module
构造函数缺少一个隐式参数。如果将
（隐式p:Parameters）
添加到包含上述语句（第100行）的方法中，代码应该可以工作。
通过将以下代码添加到configs.scala中，问题已经得到解决

class WithAccumRocc extends Config(
  (pname,site,here) => pname match {
    case RoccNMemChannels => 1
    case RoccMaxTaggedMemXacts => 0
    case BuildRoCC => {
      Some((p: Parameters) =>
  Module(new AccumulatorExample()(p.alterPartial({ case CoreName => "AccumRocc" }))))
    }   
  }
)
class WithRoCCConfig extends Config(new WithAccumRocc ++ new DefaultFPGAConfig)

在此之后，使用新配置构建火箭，即make rocket config=withrocconfig

另外，请不要忘记使用相同的配置参数重新生成vivado项目和比特流。
添加了config.scala和rocc.scalaI我试图给出该参数，但它总是会引发一些错误，我不确定该参数应以何种格式提供您缺少的
