Type Members

1. trait BackendCompilationUtilities extends firrtl.util.BackendCompilationUtilities

   

   The Driver provides methods to invoke the chisel3 compiler and the firrtl compiler.

   The Driver provides methods to invoke the chisel3 compiler and the firrtl compiler. By default firrtl is automatically run after chisel. an ExecutionOptionsManager is needed to manage options. It can parser command line arguments or coordinate multiple chisel toolchain tools options.

   Examples:

   1. args = "--no-run-firrtl --target-dir my-target-dir".split(" +")
      chisel3.execute(args, () => new DUT)

   ,

   2. val optionsManager = new ExecutionOptionsManager("chisel3")
          with HasFirrtlOptions
          with HasChiselExecutionOptions {
        commonOptions = CommonOption(targetDirName = "my_target_dir")
        chiselOptions = ChiselExecutionOptions(runFirrtlCompiler = false)
      }
      chisel3.Driver.execute(optionsManager, () => new Dut)

      or via command line arguments

2. type ChiselException = chisel3.internal.ChiselException

   

3. case class ChiselExecutionFailure(message: String) extends ChiselExecutionResult with Product with Serializable

   

   Getting one of these indicates failure of some sort.

   Getting one of these indicates failure of some sort.

   message

   A clue might be provided here.

4. case class ChiselExecutionOptions(runFirrtlCompiler: Boolean = true, printFullStackTrace: Boolean = false) extends ComposableOptions with Product with Serializable

   

   Options that are specific to chisel.

   Options that are specific to chisel.

   runFirrtlCompiler

   when true just run chisel, when false run chisel then compile its output with firrtl

   Note

   this extends FirrtlExecutionOptions which extends CommonOptions providing easy access to down chain options

5. trait ChiselExecutionResult extends AnyRef

   

   This family provides return values from the chisel3 and possibly firrtl compile steps

6. case class ChiselExecutionSuccess(circuitOption: Option[Circuit], emitted: String, firrtlResultOption: Option[FirrtlExecutionResult]) extends ChiselExecutionResult with Product with Serializable

   
   circuitOption

   Optional circuit, has information like circuit name

   emitted

   The emitted Chirrrl text

   firrtlResultOption

   Optional Firrtl result, @see freechipsproject/firrtl for details

7. trait HasChiselExecutionOptions extends AnyRef

   

8. type InstanceId = chisel3.internal.InstanceId

   

9. type Module = LegacyModule
