Detailed Description

A YAML-serializable representation of an interface.

This consists of fields (vector or ground types) and nested interfaces.

Constructor & Destructor Documentation

Interface() [1/2]

llvm::yaml::MappingContextTraits< sv::InterfaceOp, Context >::Interface::Interface ( IO &  io, sv::InterfaceOp &  op  )

inline

Construct an Interface from an sv::InterfaceOp.

This is tuned to "parse" the structure of an interface that the Grand Central pass generates. The structure of Fields and Instances is documented below.

A field will look like the following. The verbatim description is optional:

sv.verbatim "// <description>" {
  firrtl.grandcentral.yaml.type = "description",
  symbols = []}
sv.interface.signal @<name> : <type>

An interface instanctiation will look like the following. The verbatim description is optional.

sv.verbatim "// <description>" {
  firrtl.grandcentral.type = "description",
  symbols = []}
sv.verbatim "<name> <symbol>();" {
  firrtl.grandcentral.yaml.name = "<name>",
  firrtl.grandcentral.yaml.dimensions = [<first dimension>, ...],
  firrtl.grandcentral.yaml.symbol = @<symbol>,
  firrtl.grandcentral.yaml.type = "instance",
  symbols = []}

Interface() [2/2]

llvm::yaml::MappingContextTraits< sv::InterfaceOp, Context >::Interface::Interface ( IO &  io )

inline

A no-argument constructor is necessary to work with LLVM's YAML library.
