Resources and Features
Clock Networks
There are 16 clock pins (CLK[15..0]) in HardCopy II devices that can
drive either the global- or regional-clock networks. The CLK pins can
drive clock ports or data inputs.
HardCopy II devices provide 16 dedicated global-clock networks and
32 regional-clock networks; the same as in Stratix II FPGAs. These clocks
are organized to provide 24 unique clock sources per device quadrant
with low skew and delay. This clocking scheme provides up to 48 unique
clock domains within the entire HardCopy II device.
clock resources and features available in HardCopy II devices.
HardCopy II devices also support the same features as the Stratix II clock
control block, which is available for each global- and regional-clock
network. The control block has two functions:
■
■
The structure and features of the HardCopy II IOE remains the same as in
Stratix II. Any feature implemented in Stratix II IOEs can be migrated to
Hardcopy II IOEs.
Clock source selection (dynamic selection for global clocks):
You user can either dynamically select between two PLL outputs,
between two clock pins (CLKp or CLKn), or a combination of the
clock pins or PLL outputs.
Clock power-down (dynamic clock enable or disable):
In HardCopy II devices, you can dynamically turn the clock off or on
in user-mode.
