Virtuoso ADEGXL: SKILL function falltime(...)

Eberhard2010

Hello Virtuoso SKILL Programmers,

I m using the ADEGXL for measuring delay, power, slewrate of some digital blocks like NAND2 NOR2 a.s.o.

As it is described in the Manual of the SKILL function fallTime, it can be applied e.g.:

wavelet=fallTime(v("/Y" ?result "tran-tran") 0.9 nil 0 nil 90 10 t "time")

=> srrWave:0x188ac0a0

 

For falltime 0.9V=VDD 0V=GND 10%-90% and multiple occurencies, i got this object.

I my transient simulation the Output Y of my circuit falls at multiple times, so the fallTime is unfortuenatly displayed as a waveform.

Now I want to know how a get the exact values out of this object "srrWave:0x188ac0a0". I mean, when the fall is detected, how often is a fall deteced, what is the outcome for each fall case seperately a.s.o.

 

Also the functionality "export results" excludes waveforms, so I have no chance to get this values out here.

Can I somehow modify the print-method for "export results" to get my desired values?

 

As this is a very common issue, I guess there's a very easy solution for it. But I don't get it yet. Maybe someone can help me out?

Kind Regards Eberhard2010

    BTW, I think you probably want the 90 and 10 arguments the other way around (according to the documentation) - but anyway, that's not the point here.

    There's not really a way to make a waveform get flattened into the ADE XL output table. You can send the expression from the calculator to a table, and then export that.

    The other alternative is to write an OCEAN script measurement in ADE XL, and then ocnPrint the results into a file, maybe.

    Probably best to contact customer support, so it can be discussed with you in more detail, and then if needed an enhancement request can be filed.

    Regards,

    Andrew.
