expression for slew rate and settling time

[susmitha@99]

Hi,

I would like to know how to give expression for slew rate and settling time using Cadence calculator. I'm able to get the results by giving entering x,y values manually in slewrate function of cadence calculator. But I would like to know how to give an expression for this, so that if in future my input pulse or common mode voltage is changed, the expression should be able to calculate the slew rate and settling time.

Kindly let me know if anyone has any idea about it.
Thank you.

First you find the threshold crossings which define the
start and end points. Save those. Then you do the math.
It's tedious and flaky so I like to paste out the sub-terms
as I validate them (you should have an expression which
will print a single value, clean).

Have you found any means of saving calculator expressions
to a "memory" or file, and recall? I find this missing in IC6.
It's what you'd really like, but second best is to save the text
from Calculator to a file, for later retrieval.
