Power
Power Distribution
Power for the FPGA is distributed through a grid to achieve
high noise immunity and isolation between logic and I/O.
Inside the FPGA, a dedicated V
rounding the logic array provides power to the I/O drivers.
An independent matrix of V
interior logic of the device. This power distribution grid pro-
vides a stable supply and ground for all internal logic, pro-
viding the external package power pins are all connected
and appropriately decoupled. Typically a 0.1- F capacitor
connected near the V
quate decoupling.
Output buffers capable of driving the specified 4- or 8-mA
loads under worst-case conditions may be capable of driv-
ing as much as 25 to 30 times that current in a best case.
Noise can be reduced by minimizing external load capaci-
tance and reducing simultaneous output transitions in the
same direction. It may also be beneficial to locate heavily
loaded output buffers near the ground pads. The I/O Block
output buffers have a slew-limited mode which should be
used where output rise and fall times are not speed critical.
Slew-limited outputs maintain their dc drive capability, but
generate less external reflections and internal noise.
