ATT3000 Series Field-Programmable Gate Arrays
Programmable Interconnect
Programmable interconnection resources in the FPGA
provide routing paths to connect inputs and outputs of
the IOBs and logic blocks into logical networks. Inter-
connections between blocks are composed from a two-
layer grid of metal segments. Specially designed pass
transistors, each controlled by a configuration bit, form
programmable interconnect points (PIPs) and switching
matrices used to implement the necessary connections
between selected metal segments and block pins.
Figure 7 is an example of a routed net. The
ORCA
Foundry Development System provides automatic rout-
ing of these interconnections. Interactive routing is also
available for design optimization. The inputs of the logic
or IOBs are multiplexers which can be programmed to
select an input network from the adjacent interconnect
segments. Since the switch connections to block inputs
are unidirectional (as are block outputs), they are
usable only for block input connection and not routing.
Figure 8 illustrates routing access to logic block input
variables, control inputs, and block outputs.
Three types of metal resources are provided to accom-
modate various network interconnect requirements:
I
General-purpose interconnect
I
Direct connection
I
Long lines (multiplexed buses and wide-AND gates)
