Custom calculator function gets objects as arguments instead of values when called from Assembler

alexstepanov75 over 4 years ago

I have a simple custom calculator function that creates two points wave. The code is below.

This function is called like this

makeLineWave(t1 t2)

Where t1 and t2 measurements were calculated before.

t1=1

t2=VAR("tt")

Where tt is a test variable

The function working fine when called from the calculator.

But when the function called from Assembler results view, it fails because x2 is not a floating point number but a wave objects like srrWave:0x64b93a80

What is the proper way to handle this?

procedure( makeLineWave( x1 x2)
let((xVec yVec wave )
wave=drCreateEmptyWaveform()
xVec=drCreateVec('double 2)
yVec=drCreateVec('double 2)

printf("%L %L\n" x1 x2)

drAddElem(xVec x1)
drAddElem(xVec x2)
drAddElem(yVec 1.0)
drAddElem(yVec 1.0)

drPutWaveformXVec( wave xVec)
drPutWaveformYVec( wave yVec)
wave
);let
);procedure

You might want to try the approach described at https://support.cadence.com/apex/ArticleAttachmentPortal?id=a1O0V000007MkO7UAK

Yes, I am familiar with this. But in this case, the arguments should be floating-point values, not a wave. So I am not sure how to apply this.

It's a bit tricky, actually, because you're creating a waveform from a number, and the normal mapping approaches kind of fall apart of you do that (there's a couple of additional mapping layers that could be used, but these don't work properly in this case - I tried).

I'll need to think about it a bit, since my initial experiments didn't work.

Alex, could you create a case for this and put me on cc? You have my email address. Then I'll pick it up and work on it... easier for me to balance the time if there's a case for it.

Thanks,

Andrew

You do, as I received notification. I've taken ownership fo the case (probably I'll dig into it tomorrow, as have a bit of a full plate for the rest of the afternoon).

Regards,

Andrew
