data HWType Source #

Representable hardware types

Constructors

Void (Maybe HWType)

Empty type. Just Size for "empty" Vectors so we can still have primitives that can traverse e.g. Vectors of unit and know the length of that vector.

String

String type

Integer

Integer type (for parameters only)

Bool

Boolean type

Bit

Bit type

BitVector !Size

BitVector of a specified size

Index !Integer

Unsigned integer with specified (exclusive) upper bounder

Signed !Size

Signed integer of a specified size

Unsigned !Size

Unsigned integer of a specified size

Vector !Size !HWType

Vector type

RTree !Size !HWType

RTree type

Sum !Identifier [Identifier]

Sum type: Name and Constructor names

Product !Identifier (Maybe [Text]) [HWType]

Product type: Name, field names, and field types. Field names will be populated when using records.

SP !Identifier [(Identifier, [HWType])]

Sum-of-Product type: Name and Constructor names + field types

Clock !Identifier

Clock type corresponding to domain Identifier

Reset !Identifier

Reset type corresponding to domain Identifier

BiDirectional !PortDirection !HWType

Tagging type indicating a bidirectional (inout) port

CustomSP !Identifier !DataRepr' !Size [(ConstrRepr', Identifier, [HWType])]

Same as Sum-Of-Product, but with a user specified bit representation. For more info, see: Clash.Annotations.BitRepresentations.

CustomSum !Identifier !DataRepr' !Size [(ConstrRepr', Identifier)]

Same as Sum, but with a user specified bit representation. For more info, see: Clash.Annotations.BitRepresentations.

Annotated [Attr'] !HWType

Annotated with HDL attributes

KnownDomain !Identifier !Integer !ActiveEdge !ResetKind !InitBehavior !ResetPolarity

Domain name, period, active edge, reset kind, initial value behavior
