Abstract: Techniques for computer-assisted routing of an electronic design for a programmable target device are described herein. In an example embodiment, a computer system displays a representation of the programmable target device in a user interface. The computer system receives first user input that indicates a first component in the electronic design for the programmable target device. The computer system determines one or more second components of the electronic design that can be routed to the first component and displays one or more visual objects that indicate the one or more second components. The computer system then receives second user input that selects a particular component from the one or more second components and stores interconnect data indicating that the first component is routed to the particular component.
