General Purpose Interconnect
General purpose interconnect, as shown in Figure 10, con-
sists of a grid of five horizontal and five vertical metal seg-
ments located between the rows and columns of logic and
IOBs. Each segment is the height or width of a logic block.
Switching matrices join the ends of these segments and
allow programmed interconnections between the metal grid
segments of adjoining rows and columns. The switches of
an unprogrammed device are all non-conducting. The con-
nections through the switch matrix may be established by
the automatic routing or by selecting the desired pairs of
matrix pins to be connected or disconnected. The legiti-
mate switching matrix combinations for each pin are indi-
cated in Figure 11.
Special buffers within the general interconnect areas pro-
vide periodic signal isolation and restoration for improved
performance of lengthy nets. The interconnect buffers are
available to propagate signals in either direction on a given
general interconnect segment. These bidirectional (bidi)
buffers are found adjacent to the switching matrices, above
and to the right. The other PIPs adjacent to the matrices
are accessed to or from Longlines. The development sys-
tem automatically defines the buffer direction based on the
location of the interconnection network source. The delay
calculator of the development system automatically calcu-
lates and displays the block, interconnect and buffer delays
for any paths selected. Generation of the simulation netlist
with a worst-case delay model is provided.
Direct Interconnect
Direct interconnect, shown in Figure 12, provides the most
efficient implementation of networks between adjacent
CLBs or I/O Blocks. Signals routed from block to block
using the direct interconnect exhibit minimum interconnect
propagation and use no general interconnect resources.
For each CLB, the X output may be connected directly to
the B input of the CLB immediately to its right and to the C
input of the CLB to its left. The Y output can use direct inter-
connect to drive the D input of the block immediately above
and the A input of the block below. Direct interconnect
should be used to maximize the speed of high-performance
portions of logic. Where logic blocks are adjacent to IOBs,
direct connect is provided alternately to the IOB inputs (I)
and outputs (O) on all four edges of the die. The right edge
provides additional direct connects from CLB outputs to
adjacent IOBs. Direct interconnections of IOBs with CLBs
are shown in Figure 13.
