Documentation
Arguments
| :: HasCallStack | |
| => Text | Blackbox function name |
| -> [Id] | Identifiers binding the primitive/blackbox application |
| -> [Either Term Type] | Arguments of the primitive/blackbox application |
| -> NetlistMonad (BlackBoxContext, [Declaration]) |
Generate the context for a BlackBox instantiation.
prepareBlackBox :: Text -> BlackBox -> BlackBoxContext -> NetlistMonad (BlackBox, [Declaration]) Source #
Arguments
| :: Text | Blackbox function name |
| -> Identifier | LHS of the original let-binder. Is used as a name hint to generate new names in case the argument is a declaration. |
| -> Int | Argument n (zero-indexed). Used for error message. |
| -> Term | |
| -> NetlistMonad ((Expr, HWType, Bool), [Declaration]) |
extractPrimWarnOrFail Source #
Arguments
| :: HasCallStack | |
| => Text | Name of primitive |
| -> NetlistMonad CompiledPrimitive |
Extract a compiled primitive from a guarded primitive. Emit a warning if the guard wants to, or fail entirely.
Arguments
| :: Bool | Put BlackBox expression in parenthesis |
| -> Bool | Treat BlackBox expression as declaration |
| -> NetlistId | Id to assign the result to |
| -> PrimInfo | Primitive info |
| -> [Either Term Type] | Arguments |
| -> [Declaration] | Tick declarations |
| -> NetlistMonad (Expr, [Declaration]) |
Arguments
| :: HasCallStack | |
| => Identifier | Identifier to assign the final result to |
| -> NetlistId | Id to assign the final result to |
| -> TyConMap | |
| -> [Term] | The arguments to |
| -> NetlistMonad [Declaration] |
Turn a mealyIO expression into a two sequential processes, one "initial"
process for the starting state, and one clocked sequential process.
collectBindIO :: NetlistId -> [Term] -> NetlistMonad (Expr, [Declaration]) Source #
Collect the sequential declarations for bindIO
collectAppIO :: NetlistId -> [Term] -> [Term] -> NetlistMonad (Expr, [Declaration]) Source #
Collect the sequential declarations for appIO
unSimIO :: TyConMap -> Term -> Term Source #
Unwrap the new-type wrapper for things of type SimIO, this is needed to allow applications of the `State# World` token to the underlying IO type.
XXX: this is most likely needed because Ghc2Core that threw away the cast that this unwrapping; we should really start to support casts.
Arguments
| :: HasCallStack | |
| => Id | Identifier binding the encompassing primitive/blackbox application. Used
as a name hint if |
| -> Term | The function argument term |
| -> NetlistMonad ((Either BlackBox (Identifier, [Declaration]), WireOrReg, [BlackBoxTemplate], [BlackBoxTemplate], [((Text, Text), BlackBox)], BlackBoxContext), [Declaration]) |
Create an template instantiation text and a partial blackbox content for an argument term, given that the term is a function. Errors if the term is not a function
