VHDL-AMS PLI and a Question about the Simulation Cycle

Hi All,

I hope this is the right forum for my questions. If not, please let me
know and I can post elsewhere.

My first question was about whether there are any plans for a
standardized Programming Language Interface for VHDL-AMS. I did come
across the VHDL PLI site http://www.vhdl.org/vhdlpli/ but am not sure
what the status is there.

Also, I was seeking a clarification on the simulation cycle as described
in the LRM. My question is related to step (g) where the next simulation
time is determined. The text says that the next simulation cycle "...is
determined by setting it to the earliest of :
	- The value of type universal_time corresponding to TIME'HIGH
	- The next time at which a driver becomes active, or
	- The next time at which a process resumes..."
Does this imply that the analog solver must execute at every digital
event?
	 
Thanks,
