Abstract: A method of implementing a circuit design in a circuit design tool for configuration in a programmable integrated circuit (IC) connected to components on a circuit board is described. The method includes processing a first file associated with the circuit board to obtain descriptions of circuit board interfaces of the components on the circuit board; displaying a graphic user interface (GUI) of the circuit design tool to connect a circuit board interface described in the first file with a circuit design interface in the circuit design; generating physical constraints on the circuit design interface with respect to input/outputs of the programmable IC described as being connected to the selected circuit board interface; and generating a bitstream to configure the programmable IC. The bitstream includes a physical implementation of the circuit design satisfying the physical constraints.
