group of eight LEs is combined into an LAB; LABs are arranged into rows
and columns. The I/O pins are supported by I/O elements (IOEs) located
at the ends of rows and columns. Each IOE contains a bidirectional I/O
buffer and a flipflop that can be used as either an input or output register.
Signal interconnections within FLEX 8000 devices and between device
pins are provided by the FastTrack Interconnect, a series of fast,
continuous channels that run the entire length and width of the device.
IOEs are located at the end of each row (horizontal) and column (vertical)
