Definition at line 57 of file ImportVerilogInternals.h.
◆ bodySym
| const slang::ast::Symbol* circt::ImportVerilog::FlattenedIfacePort::bodySym |
the interface body member (VariableSymbol , NetSymbol)

◆ direction

◆ ifaceInstance
| const slang::ast::InstanceSymbol* circt::ImportVerilog::FlattenedIfacePort::ifaceInstance = nullptr |
The connected interface instance backing this port (if any).
This enables materializing virtual interface handles from interface ports.

◆ loc
| Location circt::ImportVerilog::FlattenedIfacePort::loc |

◆ modportPortSym
| const slang::ast::Symbol* circt::ImportVerilog::FlattenedIfacePort::modportPortSym = nullptr |
For modport-typed iface ports, the ModportPortSymbol this was flattened from.
Slang resolves in-body accesses like bus.member to a HierarchicalValueExpression whose symbol is the ModportPortSymbol, not the underlying interface body variable, so we register both keys in valueSymbols to make the lookup find this port's BlockArgument.
