implement custom logic. Row and column interconnects provide signal interconnects
between the logic array blocks (LABs).
The logic array consists of LABs, with 10 logic elements (LEs) in each LAB. An LE is a
small unit of logic providing efficient implementation of user logic functions. LABs
are grouped into rows and columns across the device. The MultiTrack interconnect
provides fast granular timing delays between LABs. The fast routing between LEs
provides minimum timing delay for added levels of logic versus globally routed
interconnect structures.
The MAX II device I/O pins are fed by I/O elements (IOE) located at the ends of LAB
rows and columns around the periphery of the device. Each IOE contains a
bidirectional I/O buffer with several advanced features. I/O pins support Schmitt
trigger inputs and various single-ended standards, such as 66-MHz, 32-bit PCI, and
LVTTL.
MAX II devices provide a global clock network. The global clock network consists of
four global clock lines that drive throughout the entire device, providing clocks for all
resources within the device. The global clock lines can also be used for control signals
such as clear, preset, or output enable.
