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 lenght of that vector.

String

String type

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 [HWType]

Product type: Name and field types

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

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

Clock !Identifier !Integer !ClockKind

Clock type with specified name and period

Reset !Identifier !Integer !ResetKind

Reset type corresponding to clock with a specified name and period
