Documentation

data BlackBoxMeta Source #

See Clash.Primitives.Types.BlackBox for documentation on this record's fields. (They are intentionally renamed to prevent name clashes.)

Constructors

BlackBoxMeta
Fields bbOutputReg :: Bool bbKind :: TemplateKind bbLibrary :: [BlackBoxTemplate] bbImports :: [BlackBoxTemplate] bbFunctionPlurality :: [(Int, Int)] bbIncludes :: [((Text, Text), BlackBox)] bbRenderVoid :: RenderVoid bbResultNames :: [BlackBox] bbResultInits :: [BlackBox]

emptyBlackBoxMeta :: BlackBoxMeta Source #

Use this value in your blackbox template function if you do want to accept the defaults as documented in Clash.Primitives.Types.BlackBox.

type BlackBoxFunction Source #

Arguments

= Bool	Indicates whether caller needs a declaration. If set, the function is still free to return an expression, but the caller will convert it to a declaration.
-> Text	Name of primitive
-> [Either Term Type]	Arguments
-> [Type]	Result types
-> NetlistMonad (Either String (BlackBoxMeta, BlackBox))

A BlackBox function generates a blackbox template, given the inputs and result type of the function it should provide a blackbox for. This is useful when having a need for blackbox functions, ... TODO: docs

type BlackBoxTemplate = [Element] Source #

A BlackBox Template is a List of Elements TODO: Add name of function for better error messages

data TemplateKind Source #

Constructors

TDecl
TExpr

data Decl Source #

Component instantiation hole. First argument indicates which function argument to instantiate. Third argument corresponds to output and input assignments, where the first element is the output assignment, and the subsequent elements are the consecutive input assignments.

The LHS of the tuple is the name of the signal, while the RHS of the tuple is the type of the signal

Constructors

Decl

Fields

!Int
Argument position of the function to instantiate
!Int
Subposition of function: blackboxes can request multiple instances to be rendered of their given functions. This subposition indicates the nth function instance to be rendered (zero-indexed).
This is a hack: the proper solution would postpone rendering the function until the very last moment. The blackbox language has no way to indicate the subposition, and every ~INST will default its subposition to zero. Haskell blackboxes can use this data type.
[(BlackBoxTemplate, BlackBoxTemplate)]
(name of signal, type of signal)
