I/O Pad Drivers
All pad drivers are capable of being tristate. Each buffer
connects to an associated I/O module with four signals: OE
(Output Enable), IE (Input Enable), DataOut, and DataIn.
Certain special signals used only during programming and
test also connect to the pad drivers: OUTEN (global output
enable), INEN (global input enable), and SLEW (individual
slew selection). See Figure 5.
Special I/Os
The special I/Os are of two types: temporary and permanent.
Temporary special I/Os are used during programming and
testing. They function as normal I/Os when the MODE pin is
inactive. Permanent special I/Os are user programmed as
either normal I/Os or special I/Os. Their function does not
change once the device has been programmed. The
permanent special I/Os consist of the array clock input
buffers (CLKA and CLKB), the hard-wired array clock input
buffer (HCLK), the hard-wired I/O clock input buffer
(IOCLK), and the hard-wired I/O register preset/clear input

buffer (IOPCL). Their function is determined by the I/O
macros selected.
Clock Networks
The ACT 3 architecture contains four clock networks: two
high-performance dedicated clock networks and two general
purpose routed networks. The high-performance networks
function up to 200 MHz, while the general purpose routed
networks function up to 150 MHz.
Dedicated Clocks
Dedicated clock networks support high performance by
providing
performance. Dedicated clock networks contain no
programming elements in the path from the I/O Pad Driver to
the input of S-modules or I/O modules. There are two
dedicated clock networks: one for the array registers (HCLK),
and one for the I/O registers (IOCLK). The clock networks
are accessed by special I/Os.
