Propagation of quantity values from top level
May 13th, 2003, 8:03pm

Does anyone have an opinion (LRM backable would be highly appreciated) on the following scenario ?

If a top-level component instantiation has a terminal port (say TT) and an across quantity (TQ) initialized to
a value xx, does/should this initial value "propagate" onto (and thus be observable in) an across quantity (Q) declared across the terminal port (T) of the actual component ?
It does make sense that this happen for values while
simulation is in the time domain etc, but what about during initialization ?

A picture is a 1K words so here's the situation:

------Top Level Instance------
 |-------------------                 |
 |                       |      T         |
 |                       |-----o         |------O TT
 |                       |                 |     across quantity TQ:=XX
 |                       | across      |
 |                       |   qty         |
 |-------------------       Q= ?   |

Thanks much,

There might be a spoon.

I would say yes, it should be propagated, but I would have to try to simulate to be sure. Notice that actual simulators do not always respect the IEEE standard.

BTW, Ken, would it be possible to have a feature to include small pictures in the posts. IMHO, this could be very helpful.
