Monte Carlo "sensitivity" analysis, comparator offset
Oct 26th, 2009, 2:33pm
 
I am simulating comparator DC offset using Monte Carlo analysis in Eldo.  Is there a way to do a sort of "sensitivity" analysis so that eldo can point me to the devices that contribute the most to the offset ?  That way, I can pinpoint those devices and upsize them to get the most bang for the buck...

Thanks in advance

I also want to measure the DC offset of a compatator.

A method mentioned in this paper could sovle the problem.

I've read through the paper and think that the method will work. Unfortunately, by now,  I haven't figured out how to save the MonteCarlo simulation results into a file.

Hope some experts  helps us out! By the way, I use spectre to do the MC simulation and use Matlab to do the post-processing.

Thanks in advance.

Hi ,

      There is one tool out there - SOLIDO VARIATION DESIGNER. Itegrated with Virtuoso, can work with HSPICE  netlist too. They basically hack your simulator engine to run your desired MC simulation/ corner simulation. What is extra is all kind of post processing, backannotation of any particular result to ADE, sensitivity analysis and so on.
