VAR() returns a waveform instead of a number, after simulation finished in ADEXL

Hi All

I am developing some code to process the simulation data.

Where I want to use VAR() as one of the arguments (selExpr ) for the function. Please find the procedure below.

procedure(SIScalcWaveCase(selExpr listOfClauseList)
prog(
(
)     ;local variable

    foreach(clauseList listOfClauseList
        when(selExpr == car(clauseList)
            return(eval(cadr(clauseList)))    
        );when
    );foreach
);prog
);proc

I expect VAR() returns a number, thus I assume selExpr would be "float" type.

But somehow it returns a waveform.

Below is the expression I made for selecting the waveform due to the value of "ctrl" in the ADEXL.

SIScalcWaveCase(VAR("ctrl") list('(0 VT("/s<0>")) '(1 VT("/s<1>")) '(2 VT("/s<2>")) '(3 VT("/s<3>"))))

where "ctrl" is a variable, whose value is swept from 0 to 3, and s<3:0> are the nets saved in the schematic.

I set breaking point in the procedure.

I notice the procedure has been called twice during the simulation in ADEXL (only 1 run)

In the first time, the VAR() indeed passes a number, and on the second time it passes a waveform.

Thus in the end, there is nothing in the results tab in ADEXL.

I run the same thing inside ADE L, and the procedure works properly there.

From my point of view, inside ADE XL, the second triggering for the procedure causes the problem.

So, I'd like to ask, why the procedure has been called twice inside ADE XL; and how to retrieve the value from VAR() properly under this condition.

Best Regards
