Embodiments relate to an interactive routing of connections in a circuit where connections associated with an initial pin of a circuit element (e.g., a row of FinFETs) are replicated in association with at least one other pin of the circuit element or a different circuit element in the circuit. The replication of connections can be performed intelligently by taking into account mapping of pins as well as design rules or other restrictions imposed on the circuit. The connections can be in form of trunks and branches, and are displayed as user inputs are received. A digital representation of the circuit with the connections as displayed is also generated. At least some of the connections in the circuit are replicated without individual user inputs based on user inputs associated with a connection to the initial pin.
