Hi Vivek,

You better stick at ocean which is meant for this kind of tasks.
Cadence comes with a corner analysis tool but your PDK/Model files have to be geared to feed that tool. In my previous company  we used to have a nice-inhouse GUI to deal with the corners.

If you want to stick at the command lines, then spectre -h would give you all the information you might need.

Again, Ocean is the choice I would advise.

Cheers,
Riad.

Is there someone who use Matlab as frontend for spectre and result backprocessing?

We found that serious simulation result analysis and backprocessing requires a powerful, userfriendly, function rich and powerful scripting enviroment. That is Matlab period.

We actual run many test bench analysis scripts trough Matlab. But there is no frontend for Matlab which allows to make a complete script simulator control. That mean that all control structures like netlist composition, corner, variation and mismatch parameter control, simulator start and load distribution should be made by Matlab.

I found only a tool here

http://www.sawtootheda.com/simcontrol.html

But they do not show how the sim result are processed.

The ADE XL could import Matlab script results but only as a function result similar to the calculator expression. But we need that Matlab is the control master because depending on the sim results of a previous sim run further changes in the sim parameter setup are made by the Matlab script.

SpectreMDL is restricted to the function evaluation and Ocean is far away from the quite user experience with Matlab.

Seems to me that Mathworks should better made a SimControl like above which work with all sim vendors including opensource spice which could run on clouds or farms.
