# This file contains various constraints for your chip including the
7
# target clock period, the capacitive load of output pins, and any
8
# input/output delay constraints.

# This constraint sets the target clock period for the chip in
12
# nanoseconds. Note that the first parameter is the name of the clock
13
# signal in your verlog design. If you called it something different than
14
# clk you will need to change this. You should set this constraint
15
# carefully. If the period is unrealistically small then the tools will
16
# spend forever trying to meet timing and ultimately fail. If the period
17
# is too large the tools will have no trouble but you will get a very
18
# conservative implementation.

# This constrainst sets the load capacitance in picofarads of the
23
# output pins of your design. 4fF is reasonable if your design is
24
# driving another block of on-chip logic.
