vosim tr freq nCycles decay

      trig - starts a vosim pulse when a transition from
             non-positive to positive occurs and no other
             vosim is still going.  a-rate will produce
             sample accurate triggering.

      freq - sets the frequency of the squared sinewave.

   nCycles - sets the number of squared sinewaves to use
             in one vosim pulse.  nCycles gets checked
             when VOSIM receives a trigger.

     decay - sets the decay factor.
