    Abstract: A programmable logic device has many regions of programmable logic, together with relatively general-purpose, programmable, interconnection resources that can be used to make interconnections between virtually any of the logic regions. In addition, various types of more local interconnection resources are associated with each logic region for facilitating the making of interconnections between adjacent or nearby logic regions without the need to use the general-purpose interconnection resources for those interconnections. The local interconnection resources support flexible clustering of logic regions via relatively direct and therefore high-speed interconnections, preferably in both horizontal and vertical directions in the typically two-dimensional array of logic regions. The logic region clustering options provided by the local interconnection resources are preferably boundary-less or substantially boundary-less within the array of logic regions.

    Abstract: PROBLEM TO BE SOLVED: To provide an FPGA transceiver capable of operating over extremely wide frequency ranges. SOLUTION: A field-programmable gate array (FPGA) may include data receiver and/or transmitter circuitry that is adapted to receive and/or transmit data at any frequency(ies) or data rate(s) in a wide range of possible frequencies or data rates. Phase-locked loop (PLL) circuitry may be needed for operation of such receiver and/or transmitter circuitry. For satisfactory operation over the wide frequency range, multiple PLL circuits are provided. One of these PLL circuits may be capable of operating over the entire frequency range, possibly with better jitter performance in some portions of the range than in other portions of the range. One or more other PLL circuits may be provided that are focused on particular parts of the broad range, especially where the jitter performance of the first PLL may not be adequate to meet some possible needs.

    Abstract: PROBLEM TO BE SOLVED: To provide a programmable duty cycle adjustment circuitry suitable for correcting duty-cycle distortions for a data signal caused by a transmission medium.
    SOLUTION: The programmable duty cycle adjustment circuitry (306a, 306b; 404a, 404b) can be provided to correct duty cycle distortion in serial data transmission systems. The duty cycle adjustment can be executed prior to transmitting data signals via the transmission medium (104). The duty cycle adjustment can also be executed when data signals are received from the transmission medium. The programmable duty cycle adjustment circuitry can be configured so as to adjust the rising and falling of the data signals. The programmable duty cycle adjustment circuitry can also be configured so as to adjust the common mode level of the data signals. The amount of the duty cycle adjustment can be determined by end-users or via negative feedback.

    Abstract: PROBLEM TO BE SOLVED: To provide an interconnection resource for applying to a programmable logic device for increasing the operating speed of a programmable logic array integrated circuit device. SOLUTION: A programmable logic integrated circuit device (10) has a plurality of programmable logic regions (20), disposed on the device with a plurality of intersecting the rows and columns of such regions. Interconnection resources for making programmable interconnections to, from and/or between the regions (e.g., interconnecting conductors or the like) are provided on the device. At least some of these interconnection resources are constituted of two forms, that are architecturally similar but that have markedly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources (200a, 210a, 230a) may have what is called a "normal signal speed", while the smaller of the portions (200b, 210b, 230b) has a significantly higher signal speed.
