case class
EnumComponentAnnotation(target: Named, enumTypeName: String) extends SingleTargetAnnotation[Named] with Product with Serializable
An annotation for strong enum instances that are not inside of Vecs
An annotation for strong enum instances that are not inside of Vecs
- target
the enum instance being annotated
- enumTypeName
the name of the enum's type (e.g. "mypackage.MyEnum")
- case class EnumComponentChiselAnnotation(target: internal.InstanceId, enumTypeName: String) extends ChiselAnnotation with Product with Serializable
-
case class
EnumDefAnnotation(typeName: String, definition: Map[String, BigInt]) extends NoTargetAnnotation with Product with Serializable
An annotation for enum types (rather than enum instances).
An annotation for enum types (rather than enum instances).
- typeName
the name of the enum's type (e.g. "mypackage.MyEnum")
- definition
a map describing which integer values correspond to which enum names
- case class EnumDefChiselAnnotation(typeName: String, definition: Map[String, BigInt]) extends ChiselAnnotation with Product with Serializable
-
case class
EnumVecAnnotation(target: Named, typeName: String, fields: Seq[Seq[String]]) extends SingleTargetAnnotation[Named] with Product with Serializable
An annotation for Vecs of strong enums.
An annotation for Vecs of strong enums.
The fields parameter deserves special attention, since it may be difficult to understand. Suppose you create a the following Vec:
VecInit(new Bundle { val e = MyEnum() val b = new Bundle { val inner_e = MyEnum() } val v = Vec(3, MyEnum()) }
Then, the fields parameter will be: Seq(Seq("e"), Seq("b", "inner_e"), Seq("v")). Note that for any Vec that doesn't contain Bundles, this field will simply be an empty Seq.
- target
the Vec being annotated
- typeName
the name of the enum's type (e.g. "mypackage.MyEnum")
- fields
a list of all chains of elements leading from the Vec instance to its inner enum fields.

This is the documentation for Chisel.
Package structure
The chisel3 package presents the public API of Chisel. It contains the concrete core types
UInt
,SInt
,Bool
,FixedPoint
,Clock
, andReg
, the abstract typesBits
,Aggregate
, andData
, and the aggregate typesBundle
andVec
.The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.
Utility objects and methods are found in the
util
package.The
testers
package defines the basic interface for chisel testers.
