Detailed Description

A class representing a dependency between two nodes in the netlist.

The driven symbol annotation is stored as a pointer into the owning NetlistGraph's SymbolTable so that many edges referring to the same hierarchical symbol share a single backing record.

disable()

hasSymbol()

auto slang::netlist::NetlistEdge::hasSymbol ( ) const -> bool

inline

True if this edge carries a symbol annotation.

setEdgeKind()

auto slang::netlist::NetlistEdge::setEdgeKind ( ast::EdgeKind kind )

inline

setVariable()

auto slang::netlist::NetlistEdge::setVariable ( SymbolReference const * sym, DriverBitRange newBounds ) -> bool

inline

Associate a driven symbol / bit range with this edge.

If the edge already carries an annotation for the same hierarchical symbol and the new range is contiguous (abutting or overlapping) with the existing one, widen the stored bounds to the union of both ranges. Returns true if the annotation was set or merged successfully, false if the edge already carries a range for the same symbol that is not contiguous with newBounds — the caller must create a separate edge in that case.

Symbol identity is by pointer: the SymbolTable interns each hierarchical path to a single canonical record, so equal paths share the same pointer.
