Programmable Interconnect Array
Logic is routed between LABs on the PIA. This global bus is a
programmable path that connects any signal source to any destination on
the device. All MAX 7000B dedicated inputs, I/ O pins, and macrocell
outputs feed the PIA, which makes the signals available throughout the
entire device. Only the signals required by each LAB are actually routed
from the PIA into the LAB.
Figure 5
shows how the PIA signals are routed
into the LAB. An EEPROM cell controls one input to a two-input
AND
gate,
which selects a PIA signal to drive into the LAB.
