fn connect_terminal( &mut self, terminal: &TerminalId<Self>, net: Option<Self::NetId> ) -> Option<Self::NetId>

Connect a terminal to a net. Returns the old connected net, if any.
source§

fn disconnect_terminal( &mut self, terminal: &TerminalId<Self> ) -> Option<Self::NetId>

Disconnect the terminal from any connected net. Returns the old connected net, if any.
source§

fn replace_net(&mut self, old_net: &Self::NetId, new_net: &Self::NetId)

Take all terminals that are connected to old_net and connect them to new_net instead. The old net is no longer used and removed. Read more

fn flatten_circuit_instance(&mut self, circuit_instance: &Self::CellInstId)

Replace the circuit instance with its contents. Remove the circuit instance afterwards. Does not purge nets nor unconnected instances. So there could be unconnected nets or unconnected instances. Read more
source§

fn flatten_circuit(&mut self, circuit: &Self::CellId)

Flatten all instances of this circuit by replacing them with their content. Remove the circuit from the netlist afterwards. For top level circuits this is equivalent to removing them.
source§

fn purge_nets_in_circuit(&mut self, circuit_id: &Self::CellId) -> usize

Delete all unconnected nets in this circuit. Return number of purged nets.
source§

fn purge_nets(&mut self) -> usize

Delete all unconnected nets in all circuits. Return number of purged nets.
source§

fn create_net_names_in_circuit( &mut self, circuit_id: &Self::CellId, prefix: &str )

Create names for all unnamed nets in the specified circuit. The names will consist of the prefix and an appended number. After calling this method, no net inside this circuit will be unnamed.
