Hi Mark,
I had to convert an analog signal into a digital one. I used a process sensitive to ana_sig'above(vth) in which I affected dig_sig to either '0' or '1'... I don't know if there is a more elegant way to do this, in case I am interested to learn.
In your case, you may try to write a process sensitive to ana_sig'above(vth) where vth is ana_sig(k-1)+ana_step
and ana_step will define your vertical tracking resolution (and so your simulation time).
Let me know if this works, I didn't try it.
