Get error when generate verilog.

[DavidZyy]

I use the following codes to generate verilog using this repository as template:

object myMultipierMain extends App {
  val path = "~/project/CPU/playground/generated"
  val firtoolOptions = Seq (
      FirtoolOption("--disable-all-randomization"),
      FirtoolOption("--lowering-options=disallowLocalVariables, locationInfoStyle=none"),
      FirtoolOption("--lowering-options=locationInfoStyle=none")
  )
  emitVerilog(new TestOneHot(), Array("--target-dir", path), firtoolOptions)
}

but get error:

the same codes can generate verilog successfully under another project. Can anyone give me some advice?

[DavidZyy]

After a painful examination, I find there is a value named lazymodule in the object playground of build.sc. and Its initial value is freechips.rocketchip.system.ExampleRocketSystem. I modify the value to the name of moudle(playground.TestOneHot) that I want to get verilog, and then I run the mill playground.verilog in shell, but still get error, I have no idea about this problem. Hope to get some advice.

Could not start a Mill server process.
This could be caused by too many already running Mill instances or by an unsupported platform.
