摘要： A PLD includes a plurality of logic blocks, a test circuit, and a test pin set. The logic blocks are coupled to gating circuits that selectively adjust an operating voltage for the blocks in response to control signals. During operation of the PLD, the control signals are updated in response to externally-generated signals provided to the PLD via the test pin set and routed to the logic blocks using the test circuit.

摘要： A method of operating a programmable logic device includes the steps of using a full VDD supply voltage to operate a first set of active blocks of the programmable logic device, and using a reduced supply voltage (e.g., 0.9 VDD) to operate a second set of active blocks of the programmable logic device. A timing analysis is performed to determine the maximum available timing slack in each active block. Active blocks having a smaller timing slack are grouped in the first set, and are coupled to receive the full VDD supply voltage. Active blocks having a larger timing slack are grouped in the second set, and are coupled to receive the reduced VDD supply voltage. As a result, the active blocks in the second set exhibit reduced power consumption, without adversely affecting the overall speed of the programmable logic device.

摘要： A method of operating a programmable logic device, including the steps of enabling resources of the programmable logic device being used in a circuit design implemented by the programmable logic device, and disabling unused or inactive resources of the programmable logic device that are not being used in the circuit design. The step of disabling can include de-coupling the unused or inactive resources from one or more power supply terminals. Alternatively, the step of disabling can include regulating a supply voltage applied to the unused or inactive resources. The step of disabling can be performed in response to configuration data bits stored by the programmable logic device and/or in response to user controlled signals. The step of disabling can be initiated during design time and/or run time of the programmable logic device.

摘要： A method of operating a programmable logic device, including the steps of using a full VDD supply voltage to operate one or more active blocks of the programmable logic device, and using a reduced supply voltage (e.g., ½ VDD) to operate one or more inactive blocks of the programmable logic device. The full VDD supply voltage and reduced supply voltage can be provided to the blocks of the programmable logic device through high-voltage n-channel transistors. A boosted voltage, greater than VDD, is applied to the gate of an n-channel transistor to provide the full VDD supply voltage to an active block. A standby voltage, less than VDD, is applied to the gate of an n-channel transistor to provide the reduced supply voltage to an inactive block. The inactive blocks can be determined during run time and/or design time of the programmable logic device.

摘要： A series capacitor coupling (SCC) structure is controllable to capacitively couple a data input lead of the SCC structure to an output lead of the SCC, or to de-couple the data input lead from the data output lead. An SCC is controlled by a control bit stored in an associated memory cell. A multiplexer is fashioned out of a plurality of such SCC structures such that the edges of a digital signal received on a selected one of a plurality of multiplexer data input leads is coupled through the SCC structures onto an intervening node. The edges of the digital signal on the intervening node are then latched to recreate the incoming digital signal and the latched signal is output onto a multiplexer data output lead. The multiplexer is very fast and has a low leakage current in comparison to conventional transmission gate multiplexers used in programmable logic devices.

摘要： A plurality of FPGA dice is disposed upon a semiconductor substrate. In order to supply the immense power required by the plurality of FPGA dice, power is routed through the semiconductor substrate vertically from thick metal layers and large integral metal structures located on the other side of the semiconductor substrate. Because the semiconductor substrate has a different coefficient of thermal linear expansion than metal layers in contact with the substrate, delamination may occur when the structure is subject to changes in temperature. To prevent delamination of metal layers connected to the semiconductor substrate and in electrical contact with the integral metal structures, the integral metal structures are manufactured with an array of post portions. During changes in temperature, the post portions of the integral metal structures bend and slide relative to metal layers connected to the semiconductor substrate and prevent linear stresses that may otherwise cause delamination.

摘要： Low temperature bond balls connect two structures having disparate coefficients of linear thermal expansion. An integrated circuit is made to heat the device such that the low temperature bond balls melt. After melting, the bond balls solidify, and the device is operated with the bond balls solidified. In one example, one of the two structures is a semiconductor substrate, and the other structure is a printed circuit board. The integrated circuit is a die mounted to the semiconductor substrate. The bond balls include at least five percent indium, and the integrated circuit is an FPGA loaded with a bit stream. The bit stream configures the FPGA such that the FPGA has increased power dissipation, which melts the balls. After the melting, a second bit stream is loaded into the FPGA and the FPGA is operated in a normal user-mode using the second bit stream.
