Clocks
Clocks are important as they have a large effect on your design’s timing accuracy,
performance, and reliability. Problems associated with the clocks can cause functional
and timing problems in the design. Pay attention to the following sub-sections that are
related to clocks when you are in the designing stage.
Global Clock Pins and Clock Networks
Use dedicated clock pins and global clock routing for clock signal input to your
design. The dedicated clock pins drive the clock network directly, ensuring lower
skew compared to using normal I/O pins. High clock skew might cause hold time
violation. The clock network drives the entire Cyclone III device and you can use the
global clock to drive all the features in the device, for example the M9K memory and
logic array blocks. Using the clock network ensures you have a predictable and more
constant delay for signals that have high fan-out. You can also use the clock pins and
clock network to drive control signals such as asynchronous reset.
For more information about the global clock pins and clock networks, refer to the
Clock Networks and PLLs in Cyclone III Devices
Device Handbook.
Internally Generated Clocks
Combinational logic output is not immune to glitches as it depends on the inputs to
the circuit. The input signals may arrive at the combinational logic circuit at different
times and cause glitches. Moreover, the input signals may have glitches and the
combinational logic circuitry does not filter out these glitches. If you use this
combinational logic output signal as a clock to other circuitries, these glitches can
cause functional problems.
Always register the input signals to the combinational circuitry and the output signal
from that circuitry that is used as a clock
higher frequency than the clock generated internally. Registering the input signals to
the combinational circuitry ensures the arrival of the signals to the circuit is controlled
by the clock, and any glitches are filtered in the input signals. By registering the
output signals from the circuit, you can filter out any glitches generated by the
circuitry.
