Documentation
Is a type used for internal or external use
newtype AggressiveXOptBB Source #
Is '-fclash-aggresive-x-optimization-blackbox' set?
Constructors
| AggressiveXOptBB Bool |
Kind of a HDL type. Used to determine whether types need conversions in order to cross top entity boundaries.
Constructors
| PrimitiveType | A type defined in an HDL spec. Usually types such as: bool, bit, .. |
| SynonymType | A user defined type that's simply a synonym for another type, very much like a type synonym in Haskell. As long as two synonym types refer to the same type, they can be used interchangeably. E.g., a subtype in VHDL. |
| UserType | User defined type that's not interchangeable with any others, even if the underlying structures are the same. Similar to an ADT in Haskell. |
class HasIdentifierSet state => Backend state where Source #
Methods
