# The initial state AND the state the stimulus is when
# it rolls over

# all times are with respect to the cpu's cycle counter

# the asynchronous stimulus will roll over in 'period'
# cycles. Delete this line if you don't want a roll over.

# Now the cycles at which stimulus changes states are
# specified. The initial cycle was specified above. So
# the first cycle specified below will toggle this state.
# In this example, the stimulus will go high at cycle 100
# and then go low at cycle 200, high at 300, and so on

# Give the stimulus a name:

# Finally, tell the command line interface that we're done
