Expand description

Helper methods to parse @read_together and @write_together specifications

Implementations§

Source§

impl PortInterface

Source

pub fn write_together_specs<'a>( primitives: impl Iterator<Item = &'a Primitive>, ) -> HashMap<Id, Vec<HashSet<Id>>>

Construct @write_together specs from the primitive definitions.

Source

pub fn comb_path_spec(prim: &Primitive) -> CalyxResult<Vec<(Id, HashSet<Id>)>>

Construct @read_together spec from the definition of a primitive. Each spec is allowed to have exactly one output port along with one or more input ports. The specification dictates that before reading the output port, the input ports must be driven, i.e., the output port is combinationally related to the input ports and only those ports.

Source

pub fn comb_path_specs<'a>( primitives: impl Iterator<Item = &'a Primitive>, ) -> CalyxResult<HashMap<Id, Vec<(Id, HashSet<Id>)>>>

Construct @read_together specs from the primitive definitions.
