until n s0 s1 means that
eventually n s1, and up
until at least the period before
s1 holds,
s0
continuously holds.
Note: Both argument streams must have sufficient history to
drop n values from them.
True until another stream is true, within the time bounds specified.
until l u clk dist s0 s1 is true at time t iff there
exists a d, with l <= d <= u, such that
s1 is true at time (t + d), and for all times
t' with t <= t' < t + d, s0 is true
at those times.
Matching Until: Same semantics as until, except with both
s1 and s0 needing to hold at time (t + d)
instead of just s1.
