Abstract:
A programmable logic integrated circuit device (10) has a plurality of regions (20) 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 (200a, 210a, 230a) may have what may be termed normal signal speed, while a smaller minor portion (200b, 210b, 230b) 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.

For example, a major or larger portions (200a, 210a, 230a) of the dual-form interconnection resources have what is termed a normal speed, and smaller portions (200b, 210b, 230b) have a significantly faster signal speed.

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.
