Abstract
A system and method for testing a circuit implemented on a programmable logic device. A host processor is coupled to the programmable logic device via an interface device, which has a plurality of signal pins for configuring the programmable logic device. Selected pins of the interface device are connected to selected input pins of the programmable logic device. Test vectors from the host processor are applied to the selected input pins of the programmable logic device via the interface device, and the states of one or more signals appearing on one or more output pins of the device are analyzed.
