Title: event trigger of integer and real values
Post by sylak on Jul 20^th, 2007, 3:30pm

Suppose I have a

real vout_val;
integer logic1, logic2;

logic1 = V(vin1) > vtrans;
logic2 = V(vin2) > vtrans;

@ (cross(V(vin1) - vtrans, 1)) logic1 = 1;
@ (cross(V(vin1) - vtrans, -1)) logic1 = 0;

@ (cross(V(vin2) - vtrans, 1)) logic2 = 1;
@ (cross(V(vin2) - vtrans, -1)) logic2 = 0;

//
// define the logic function.
//
vout_val = (logic1 && logic2) ? vlogic_high : vlogic_low;

if an event happens in vin1 ==> change in logic1?.. will 'vout_val' change along with event based change of logic1 ? or should I include some statement for that to happen?

Assuming the above code is inside an analog block there is no need to have any additional code with the calculation of vout_val. Any code inside an analog block is evaluated with every time-step unless it is guarded by an event.
