Abstract
Improved reconfiguration techniques are provided for programmable logic devices (PLDs). For example, in accordance with an embodiment of the present invention, a programmable logic device includes logic blocks, input/output blocks and corresponding input/output pins, and configuration memory. The PLD also includes registers adapted to capture output signal values of the input/output pins before a reconfiguration of the programmable logic device and to provide the captured values on the input/output pins during the reconfiguration of the PLD.
