Title: Propagation of quantity values from top level Post by FrereTuck on May 13th, 2003, 8:03pm Folks, 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, |
Title: Re: Propagation of quantity values from top level Post by Paul on Jun 6th, 2003, 12:22am 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. |
