Abstract: A programmable logic integrated circuit device has a plurality of regions of programmable logic disposed on the device in a plurality of intersecting rows and columns of such regions. Interconnection resources (e.g., interconnection conductors, signal buffers/drivers, programmable connectors, etc.) are provided on the device for making programmable interconnections to, from, and/or between the regions. At least some of these interconnection resources are provided in two forms that are architecturally similar (e.g., with similar and substantially parallel routing) but that have significantly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources may have what may be termed normal signal speed, while a smaller minor portion may have significantly faster signal speed. Secondary (e.g., clock and clear) signal distribution may also be enhanced, and so may be input/output circuitry and cascade connections between adjacent or nearby logic modules on the device.

Abstract: Systems and methods are provided using common-mode-voltage bias circuitry to make common-mode-voltage adjustments to differential driver circuitry in integrated circuit differential communications links. Adjustable bias circuitry may be controlled using static and dynamic control signals. Dynamic control signals can be produced by core logic on a programmable logic device or other integrated circuit. Static control signals can be produced by programmable elements. Bias circuit adjustments made at one end of a differential link can be used to improve performance at either end of the link or can be used to improve power consumption or to balance power and performance considerations. The same integrated circuit design can be used in both AC-coupled and DC-coupled environments. The bias circuitry can be formed from an adjustable current source and adjustable resistor. The current source and adjustable resistors can be controlled by the same control signals.

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: An integrated circuit includes physical media attachment (“PMA”) circuitry that includes two different kinds of transceiver channels for serial data signals. One kind of transceiver channel is adapted for transceiving relatively low-speed serial data signals. The other kind of transceiver channel is adapted for transceiving relatively high-speed serial data signals. A high-speed channel is alternatively usable as phase-locked loop (“PLL”) circuitry for providing a clock signal for use by other high- and/or low-speed channels. A low-speed channel can alternatively get a clock signal from separate low-speed PLL circuitry.
