Type Members

1.  trait DataProduct[-A] extends AnyRef

   Typeclass interface for getting elements of type Data

   Typeclass interface for getting elements of type Data

   This is needed for validating DataViews targeting type A. Can be thought of as "can be the Target of a DataView".

   Chisel provides some implementations in object DataProduct that are available by default in the implicit scope.

   A

   Type that has elements of type Data

   Annotations

   @implicitNotFound()

2.  sealed class DataView[T, V <: Data] extends AnyRef

   Mapping between a target type T and a view type V

   Mapping between a target type T and a view type V

   Enables calling .viewAs[T] on instances of the target type.

   Detailed documentation

   • Explanation
   • Cookbook

   T

   Target type (must have an implementation of DataProduct)

   V

   View type

   Annotations

   @implicitNotFound()

   Example:

   1. class Foo(val w: Int) extends Bundle {
        val a = UInt(w.W)
      }
      class Bar(val w: Int) extends Bundle {
        val b = UInt(w.W)
      }
      // DataViews are created using factory methods in the companion object
      implicit val view = DataView[Foo, Bar](
        // The first argument is a function constructing a Foo from a Bar
        foo => new Bar(foo.w)
        // The remaining arguments are a variable number of field pairings
        _.a -> _.b
      )

   object DataView for factory methods

   object PartialDataView for defining non-total DataViews

3.  implicit class DataViewable[T] extends AnyRef

   Provides viewAs for types that have an implementation of DataProduct

   Provides viewAs for types that have an implementation of DataProduct

   Calling viewAs also requires an implementation of DataView for the target type

4.  case class InvalidViewException(message: String) extends ChiselException with Product with Serializable
5.  sealed trait LowPriorityDataProduct extends AnyRef

   Low priority built-in implementations of DataProduct

   Low priority built-in implementations of DataProduct

   Note

   This trait exists so that dataDataProduct can be lower priority than seqDataProduct to resolve ambiguity

6.  implicit class RecordUpcastable[T <: Record] extends AnyRef

   Provides viewAsSupertype for subclasses of Record
