wavescan waveforms -> CIW?

I'm not entirely sure I know what it would mean to "dump to CIW"? I presume you would mean to assign it to some SKILL variable? How would it know what variable to assign to?

However, you can send a waveform to the calculator (hit the "wave" button in the calculator) and then you can cut and paste the calculator expression and use it in the CIW - there's nothing particularly special about evaluating expressions in the calculator. You could then assign the expressions to variables.  You could do the same in the calculator buffer, by adding "varName=" to the beginning of an expression (captured from a waveform) and then hitting the "evaluate" button.

 Basically, I'm trying to create a function that would just return a list of the waveforms that are in the current wavescan window.  

You pointed out that I could just evaluate the expression that is placed in the calculator from the wavescan window in the CIW and get my waveform back. I didn't realize that this also worked when what was in the calculator was something like: "wave_132()"

I found that the following function does what I wanted.

procedure( GrabWS()
    let( (w_current l_wave t_wave t_expr)
        w_current = awvGetCurrentWindow()       
        l_wave = car(awvGetWaveNameList(w_current))
        l_wfm = foreach(mapcar t_wave l_wave
            sprintf(t_expr "wave_%L()" t_wave)           
            evalstring(t_expr)
        ); foreach
    );
); 

Thanks,

 So would something like this work?

procedure( GrabWS()
    let( (w_current
                l_WNL
                l_wave
                l_func
                x_index
                t_wave t_expr)
        w_current = awvGetCurrentWindow()       
        l_WNL = awvGetWaveNameList(w_current)
        l_wave = car(l_WNL)
        l_func = cadr(l_WNL)   
        x_index = -1;       
        l_wfm = foreach(mapcar t_wave l_wave
            x_index = x_index + 1
            o_ret = errset(evalstring(nth(x_index l_func)))
            if(o_ret then
                car(o_ret)
            else
                sprintf(t_expr "wave_%L()" t_wave)           
                evalstring(t_expr)
            ); if          
        ); foreach
    );
); GrabWS()

 I realize I'm resurrecting an old thread, but I haven't found a solution to this.

I'm now on version 6.14, but the situation hasn't improved.  

Basic problem is that I've got a waveform plotted in a waveform viewer (e.g. viva)  and I want access to it in the CIW.  It is possible to copy the waveform from viva to the calculator, so I know that the data exists somewhere. However, how can I reliably get at the data through skill calls?

awvGetWaveNameList() returns: list of numbers for the curves and list of corresponding names.

Unfortunately, I've found that the returned list of numbers doesn't correspond to anything that I can use to grab that waveform.

 Has anything changed with the newer versions of Cadence or is there any planned future expansion to allow access to the waveforms?

Thanks,

Mark

Hi Mark,

I don't think anything has changed yet with respect to this. I'm hoping that we'll have an overhaul of the SKILL API for interaction with the graph sometime after IC615 (once the new graph in ViVA has bedded down) - and hopefully this is something we can add then (it will be simpler as in IC615 it's a single process, rather than split between the main Virtuoso and separate Java process).

Regards,

Andrew.
