**iinteg cadence**

Hello,

I want to know the integration with time of my output signal in the time domain

The calculator in the cadence provides the integral function-- integ

When I select the output signal in the calculator and then click integ

it shows the form--Definite Integral

Signal: already filled with my output signal

initial value: ?

final value: ?

I want it to display a signal waveform which is the time integral of the output signal between 0 and 3 ms

But instead it only shows a number

So I suppose I have not filled the box initial value and final value as their correct way

Could some one tell me how to use this integrator function exactly?

or is integ the correct function to use?
