Accelerator Series FPGAs – ACT 3 Family
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
sub-nanosecond
skew
and
guaranteed
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.
