Hello all.

I've been fighting the Wavescan calculator for a while, and I can't seem to find a way to do this. So far, I have a voltage signal and its derivative (with 'deriv') successfully graphed from the results of the 'analog environment' simulation. I can also find the peak derivative ('ymax') and the voltage at which it occurs ('argmax').

I want to make calculator graph a new curve where the horizontal represents the distance to the left and right of the voltage at which the maximal derivative occurs, and the vertical represents the average of the derivative over that interval. I've tried all manner of different things, but it seems wavescan fails at even the most simple thing - like putting the current value of the swept (x-axis) variable into the calculator. Brilliantly, it neglects the current swept value and instead uses the default value entered in the 'analog environment' window.

This is in addition to a host of other inconceivable headaches, like the calculator often refusing to acknowledge the delete and backspace keys, and the analog environment adding dozens of extraneous parentheses to my expressions. If I can't resolve this in the next few days I'm looking for a new simulative environment for my project, because my experience with Cadence has been thoroughly poor.

Thanks for your help.

If you're referring to MDL, I've heard of it but I have no idea how to use it. I suppose I could look up a tutorial.
