Abstract: Disclosed approaches for dynamically creating one or more scan chains in a programmable integrated circuit (IC) include placing elements of a circuit design on first registers of the programmable IC. A processor can determine second registers of the programmable IC that are unused by the circuit design after placing the elements of the circuit design. Data-out pins of the first registers are coupled to data-in pins of the second registers, respectively, and the second registers are coupled into a scan chain.
