clip function doesn't work for reverse DC analysis

Johanny Saenz

Hi all!

I want to clip a waveform which was generated by a reverse DC analysis. Unfortunately I have found that clip function doesn't work with reversed DC waveforms.

Is there some workaround ? I have tried a composition of functions including flip without sucess.

Thanks!

    I just tried this and it worked OK, so I did some digging and found that it was fixed via CCR 1674191 in IC6.1.7.500.10 (ISR 10). I was using the latest IC617 ISR (ISR23) and it was fine, and if I went back to ISR9, it doesn't work properly.

    The workaround if using an older broken version would be to use flip, and use negative values for the clip limits and flip back again:

    flip(clip(flip(i("M1:d" ?result "dc-dc")) -2 -0.8))

    is equivalent to:

    clip(i("M1:d" ?result "dc-dc") 0.8 2.0 )

    in a fixed version.

    Regards,

    Andrew.
