Title: Derivative of a curve
Post by raja.cedt on Dec 20^th, 2015, 5:45am

Hello--Just want to check is there any in-built function available in spectre for differentiation. Basically I have CDF from a transient noise simulation and I would like to see PDF from that. Currently doing this in Matlab, but it is very tedious job forr all PVT.

Best Regards,
Raj.

Hello Raja

Did you consider using the deriv function in wavescan calculator that comes with Cadence?

Thanks and regards

Hello--
I cant see such kind of function in my calculator, I think I am using recent and most advanced version. Could you please tell me in which version you have got this option?

Raj.

Hi,
I think the function should have in almost Cadence versions. I used version 5.14 and 6.16 and if I remember correctly the function is available in these versions.

Yes, I have been using it since icfb (Cadence v5) days. It exists even in the latest 6.16 version and I do not see any good reason why Cadence would remove it. It should be under special function (or All) category in Function Panel in Calculator.
