Thank you Mr. A. Zerky for directing me to right path to find my requirements

There are multiple ways, two most used and easy method are,

1. You can export the plot data in csv format and import in tool like excel or Origin Pro to plot or merge multiple data as per requirement.

2. You can also append multiple plots in Virtuoso ADE L by choosing Append in the plot mode.

Thank you Divyesh Sachan...

I'm following 2nd method to merge the plots..

And also tried by instantiating different modules in a single cell (multiple cells under top cell).. But i'm getting deviation in results. That is by simulating the single cell alone, i'm getting delay of 4.4ns. but if multiple cells are instantiated under top cell, the same cell shows delay of 15.4ns.

Can any one tell me reason for that?

is this method correct to compare different cells?

Thanks in advance
