Function documentation

const Expression* slang::ast::ModportPortSymbol::getConnectionExpr() const

Returns an expression that represents whatever this port connects to.

For explicit connections, this just returns explicitConnection and for implicit connections this returns a NamedValueExpression that wraps the internalSymbol. Returns nullptr if there is no connection at all.

Variable documentation

const Symbol* slang::ast::ModportPortSymbol::internalSymbol

An instance-internal symbol that this port connects to, if any.

Ports that do not connect directly to an internal symbol will have this set to nullptr.
