Abstract:
1. A computer program product in a computer-readable medium for use in a first data processing system for programming a programmable logic integrated circuit device adapted to enter a low-power mode, the computer program product comprising: first instructions for combining at least one end user-specified design elements and at least one manufacturer-specified design elements into a first low-power mode control circuit to be programmed into a programmable logic block inside the programmable logic integrated circuit device, the first low-power mode control circuit forming a portion of a complete design, wherein a low-power enable input I/O pad is coupled to the first low-power mode control circuit and to a second low-power mode control circuit; second instructions for mapping the design elements of the portion of the complete design into the programmable elements forming a portion of the circuitry of the programmable logic integrated circuit device; third instructions for generating a control data structure necessary for controlling the first low power and the second low power modes of the programmable elements; and fourth instructions for transferring the control data structure into a non-volatile memory; wherein the control data structure and non-volatile memory are adapted to allow a second electronic data processing system containing the programmable logic integrated circuit device to subsequently transfer the control data structure into volatile control elements forming a portion of the circuitry of the programmable logic integrated circuit, wherein the control elements configure the programmable elements to implement the complete design.
