摘要： A more time-efficient and area-efficient approach is provided to synchronize the transfer of data into programmable logic resources. A programmable logic resource core clock and a reset signal are routed to a reset register that controls the reset of a dynamic phase alignment circuit and a data realigner. The dynamic phase alignment circuit includes a phase-locked loop circuit, a J counter, and a deserializer. When the output signal of the reset register transitions from logic 1 to logic 0, the J counter begins to count and sets an enable signal accordingly. The enable signal, which controls the output of synchronized parallel data from the deserializer, is therefore phase associated with the programmable logic resource core clock. The synchronized parallel data is input to a data realigner which outputs the data based on the programmable logic resource core clock for input to the programmable logic resource core circuitry.

摘要： Enhanced passgate structures for use in low-voltage systems are presented in which the operational speed of the passgate structures is maximized, while minimizing leakage current when the structure is turned “OFF.” In one arrangement, the VT of the pass-gate structures is increased relative to the VT of other transistors fabricated according to a particular process dimension. In addition, a passgate activation voltage is applied to the passgate structures such that the passgate activation voltage is higher in voltage than a nominal voltage being supplied to circuitry other than the passgate structures.

摘要： A serial data interface for a programmable logic device includes a receiver that deserializes a plurality of channels of received serial data using a recovered clock signal or a phase-aligned received clock signal. Byte boundaries are initially assigned, perhaps arbitrarily, and the deserialized signal is sent to the programmable logic core of the programmable logic device. Programmable logic in the core monitors the byte boundaries on each channel based on the criteria, including any user-defined parameters, programmed into the logic. If a boundary misalignment is detected, a signal is send from the core to bit-slipping circuitry on that channel of the interface to adjust the boundary. The signal could instruct the bit-slipping circuitry to adjust the boundary by the number of bits needed to correct the alignment. Alternatively, the bit-slipping circuitry could operate iteratively, adjusting the boundary by one bit, each cycle, until the signal stops indicating misalignment.
