Abstract

In accordance with an embodiment of the present invention, a programmable logic device (PLD, such as a field programmable gate array (FPGA)) includes a plurality of input/output blocks having boundary scan cells that are adapted to precondition registers within a logic area of the programmable logic device with desired signal values prior to release of control of the input/output blocks to user-defined logic provided by a reconfiguration.
