Monte Carlo Help to calculate std and mean.

[aartichoudhary@gmail.com]

Hello All,
I am trying to do monte carlo spectre standalone simulations and print
the mean and standard deviation.With the help of Skill code( Thanks to
Andrew) I am able to do it.
This is helpful only when I create a netlist from ADE and access
complete schematic directory of the design.As it has amap file having
only netlist doesn't help.

But my problem here is I have to do it on standalone spectre.
I have spectre netlist and I want to do montecarlo simulations on it.
For Monte Carlo simulation, in order to run standalone spectre
simulation, I
have to copy the entire schematic directory (~/simulation/<design
name>/<simulator
name>/schematic) and then run the simulation from the netlist directory
(under the schematic directory). As it has amap file.

I tried couple of things like.
I created netlist ran a spectre standalone simulation.
opened UNIX>icms -nograph
openResults() nothing worked.

I would be really grateful if anyone can find me a wayout to calculate
mean and standard deviation on standalone spectre.
AS I need to do for 300's of cell and opening ADE for every cell is not
a very welcome solution.

Feel free to provide me any insights.
Thank YOU!!

Thanks,
Aarti

This is actually a question related to my solution 11026072 (for those
interested). There is no need for that solution to only be used in icms - or to
require an amap directory - it will even work if you're using the "skill"
executable.

Anyway, I've communicated with Aarti directly to clarify the problem.
