Programmable Switch Matrices
The horizontal and vertical single- and double-length lines
intersect at a box called a programmable switch matrix
(PSM). Each switch matrix consists of programmable pass
transistors used to establish connections between the lines
(see Figure 26).
For example, a single-length signal entering on the right
side of the switch matrix can be routed to a single-length
line on the top, left, or bottom sides, or any combination
thereof, if multiple branches are required. Similarly, a dou-
ble-length signal can be routed to a double-length line on
any or all of the other three edges of the programmable
switch matrix.
Single-Length Lines
Single-length lines provide the greatest interconnect exi-
bility and offer fast routing between adjacent blocks. There
are eight vertical and eight horizontal single-length lines
associated with each CLB. These lines connect the switch-
ing matrices that are located in every row and a column of
CLBs.
Single-length lines are connected by way of the program-
mable switch matrices, as shown in Figure 28. Routing
connectivity is shown in Figure 27.
Single-length lines incur a delay whenever they go through
a switching matrix. Therefore, they are not suitable for rout-
ing signals for long distances. They are normally used to
conduct signals within a localized area and to provide the
branching for nets with fanout greater than one.
